I would like to know information about water conservation

Methods to save water

◆Waste by washing face and hands◇Open the faucet and splash water.

Water saving◇Control the faucet switch to small and medium water volume, and turn off the water in time.

◇Encourage the use of basins to wash your face and hands.

◆Brushing teeth waste◇Push water continuously for 30 seconds, using about 6 liters of water.

Water Saving ◇ Use a cup to collect water, a 3-cup cup requires 0.6 liters of water.

◇A family of three can save 486 liters of water per month by using it twice a day.

◆Cooking waste◇Open the faucet and rinse for a long time.

◇ If you boil water for too long, a large amount of water vapor will evaporate.

◇Rinse watermelons and fruits with tap water.

Water Saving ◇ Use paper to wipe off oil stains on cooking utensils and tableware before washing them to save water.

◇Control the flow rate of the faucet and change from uninterrupted flushing to intermittent flushing.

◆Waste in showers and baths◇If you shower continuously for too long, a lot of water will be wasted.

◇Put too much water in the bathtub, causing it to overflow.

◇When taking a bath, open the drain plug and fill the water at the same time, which is a shocking waste.

Water Saving◇Discharge water intermittently for showering. Turn off the water in time when scrubbing.

◇Avoid showering for too long.

◇The water after bathing can be used for laundry, car washing, toilet flushing, mopping, etc.

◆Waste of Laundry◇The washing machine continuously fills, showers and drains water, which requires about 165

L of water each time.

Water saving ◇The washing machine adopts washing-dehydration-water injection-dehydration-water injection-dehydration method. It uses about 110 liters of water each time.

It can save 55 liters of water each time, per month. Washing 4 times can save 220 liters of water

◇ Wash clothes together to reduce the number of washes.

◇Small items, summer clothing. Promoting hand washing can save a lot of water.

◇Add an appropriate amount of detergent. Excessive application will waste a lot of water.

◆Toilet water use◇Old toilet, 13 liters each time.

◇Water-saving toilet, 9 liters each time.

Water Saving◇Use water-saving sanitary ware.

◇Use washing water and laundry water to flush the toilet to save water.

◆Car washing waste◇Rinse with a water pipe for 20 minutes, using about 240 liters of water.

Water Saving ◇ Use buckets of water to wash the car, which requires 3 buckets of water and about 30 liters of water.

◇Use washing water and laundry water to wash the car.

◇Use machinery to automatically wash the car and treat the car wash water for recycling.

◆Put an end to waste

The waste of water is staggering. A faucet that cannot be closed tightly can drain 1-6 cubic meters of water a month; a leaking toilet can drain 3-25 cubic meters of water a month. If there are 600,000 faucets and 200,000 toilets leaking in the county, Hundreds of millions of cubic meters of water are lost each year.

Answer: MI娨娨婼伱 - Trial Period Level 1 6-10 15:50

Water, the basic substance on the earth, is so worthy of our praise! It is she who gave birth to all living beings in the world; it is she who provides energy for life so that life can survive; it is she who makes life continue to develop and become more and more prosperous and developed. Therefore, it is no exaggeration to say that "water is the source of life".

But, is water inexhaustible? We can answer with certainty: no. Although 70.8% of the earth is covered by water, 97.55% of the water is seawater, which is neither directly drinkable nor irrigated. Among the remaining 2.5% of fresh water, the water that humans can actually utilize is less than 1% of the world's total fresh water. It is true that from the emergence of primitive life on the earth until now, water has been serving life, working hard and never stopping. But I wonder if you have ever thought about it: the endurance of water has its limit, and today’s water resources are already in short supply! There are two main reasons for this situation: first, the lack of nature itself; second, man-made destruction. Of course, we cannot blame God for being unfair to us and giving us a planet short of water; on the contrary, we should thank God for creating a beautiful home for us.

However, even in this emergency situation, we humans are still wasting and destroying water resources. Due to a large amount of industrial wastewater being discharged into the Lian and Rong rivers, the water quality of the two rivers is seriously polluted. The water quality only meets Category 3 standards. It is neither drinkable nor used for irrigation. Island counties like Nan'ao rely on "God's arrangement" for their water use. ——The rainwater collection area of ??all its mountain pond reservoirs, including flood diversion projects, only accounts for 31%, and it is still difficult to use water for industrial and agricultural production and people's daily lives. It can be seen that it is urgent to properly deal with the problem of water pollution and damage. However, water shortages are serious in the world today, and wars caused by water are increasing day by day. For example, among all the resources in the Middle East, water is the most prone to crisis. Water in the Middle East is more expensive than oil. Most countries in the Middle East are severely short of water. The Middle East has been experiencing drought for more than ten years and is facing a serious water crisis. The small Jordan River has given birth to two major religions and is the most fiercely contested water source in the Middle East. All four wars in the Middle East are related to it. The Jordan Pool provides two-thirds of the water for the Lake of Galilee, Israel's main water source. The 1955 Johnston Agreement stipulated the amount of water for all parties, but only Israel signed it, and the Arab countries were to dam the Jordan River in the 1960s. In 1965, the Israeli army blew up Syria's river interception equipment. Both Arabs and Israel regarded destroying each other's water resources as their primary strategic goal. Israel occupied the Golan Heights, the source of the Jordan River. One of the problems in the Syrian-Israeli negotiations is that Israel insists on occupying most of the West Bank water resources. At present, Palestinian water resources are completely controlled by Israel. The per capita water volume is only three-quarters of that of Jewish settlers, but the payment is twice as high. Pakistan has had to over-pump groundwater, which has worsened water quality. The groundwater in the Gaza Strip has become so saline that it cannot be used. Since the violent conflict, Palestine's water resources have been left unmanaged, and water shortages have become even worse.

There is no comprehensive agreement on sharing water resources along the three major river systems in the Middle East, and disputes continue. The Nile River flows through 10 countries, and Egypt is affected due to its upstream. Egypt's construction of the Aswan Dam has solved its own water problems, but it has caused dissatisfaction among upstream countries. Whenever there is a dispute, Sudan threatens to cut off the river water. Ethiopia signed an agreement with Sudan in 1991, which allows it to withdraw 4 billion tons of river water every year. Egypt strongly opposes it. Turkey is rich in water resources. Turkey built the water south and reduced the water to Syria and Iraq. The traffic has encountered strong opposition from both countries. Turkey and Israel have reached an agreement to transport water from the Manavgat River to Israel by wheel ship. Jordan and Syria are also considering purchasing water from Turkey. Türkiye hopes to play its role as a water power and promote cooperation and stability in the Middle East. Israel wants Turkey to increase water supplies to Syria. In exchange for Syria's concessions on the Lake Gali border, Turkey was daunted by the complex Arab-Israeli dispute and refused to get involved.

It can be seen that the shortage of water resources must be buffered for a period of time. It's not easy. The only way is to save water, and Israel has done a better job in this regard. Two-thirds of Israel's land is desert, and there is no rain for seven months of the year. The per capita water resource is nearly 70 cubic meters, which is less than 1/4 of the Middle East, 3% of the world's per capita, and 1/8 of China's per capita. However, it is on this barren and water-scarce land that Israel has built modern agriculture by relying on scientific water use, which has amazed the world.

Agriculture was once the foundation of Israel. In 1952, Israel built the 145-kilometer "North-South Water Diversion" water pipeline at a cost of 1.5 billion U.S. dollars and 10 years. In the mid-1960s, The scientific water use method of drip irrigation was promoted and the agricultural economy took off. Israel's agricultural population has dropped from 60% to 3%. One farmer can feed 90 people. The per capita GDP is US$180,000, ranking among the top 12 in the world. Israel cherishes water resources very much and regards water as its lifeline. Water conservation is a systematic program involving all aspects of society. Therefore, success was achieved.

Water makes the grass greener.

Water makes flowers bloom.

Water makes big trees stand tall.

But you are haggard day by day.

Aging day by day.

Crying again and again.

If people do not cherish water resources, then the last drop of water in the world will be human tears.

Government water-saving plan

Beijing’s water-saving target for 2005 is 40 million cubic meters. Jiao Zhizhong, director of the Municipal Water Affairs Bureau, announced seven major water-saving plans: First, new and expanded The project must also install reclaimed water utilization facilities and fully implement metering management; second, the industry must set water use quotas, and large households with annual water consumption of more than one million tons must sign water supply agreements; third, the water use indicators of social units must be reduced by another 10%; fourth, The first is to complete 35 industrial water-saving technological transformations, and Yizhuang will build a water-saving demonstration zone; the fifth is to popularize water-saving appliances in households, and 50% of households will switch to water-saving appliances within the year; the sixth is to install 100 kilometers of reclaimed water pipelines within the year, and expand The scope of reclaimed water users; seventh, continue to select water-saving models, and every citizen can strive to be a water-saving model.

Water-saving plan for enterprises

We have designed a water-saving plan for enterprises. After implementing this plan (or taking measures in this plan), we guarantee that you will receive It has a very good water-saving effect, saving energy, reducing expenses, and reducing labor force, thus improving work efficiency and getting twice the result with half the effort.

The first step: Conduct a water balance test, which is the most scientific method to find out the water consumption of an enterprise (unit). After the water balance test, the unit's water pipe network, the number and usage of water appliances, the daily, monthly and annual water consumption, and the water profile of each water point (such as boiler, bathing, car flushing, swimming, etc.) will all pass Test to find out, and through water use data analysis, find out the reasons for unreasonable water use, so that corresponding measures can be taken. For specific methods and steps to conduct a water balance test, please browse the "Water Balance Test" column of this website.

Step 2: Ask for water from scientific management. Formulate a scientific water use system, adopt measures such as decomposing indicators, assigning responsibilities to people, and reducing rewards and exceeding penalties to fully mobilize people's enthusiasm. This is the basis of water conservation efforts. For specific experience, you are welcome to visit and learn from the "Northern Transportation Energy Saving Service Center".

The third step: Ask for water from science and technology and use water-saving appliances to make wasting water impossible. The specific methods are introduced as follows:

1. Use ceramic chip, variable pitch, self-closing and other leak-proof, high-tech faucets. This type of faucet not only does not leak, but also has a long service life, and is variable pitch and self-closing. The self-closing type also has the characteristics of short opening and closing time, prevention of water loss, self-closing without water pressure, etc., and all have a warranty period of more than three years.

2. The urinal (bucket) uses an infrared water-saving controller to ensure that the water flows when people come and stops when people leave. It not only achieves the effect of flushing clean and without odor, but also saves more than 70% of water. .

3. The stool pit adopts a foot valve, which is not only hygienic but also easy to use. The high box can use "Wufang" brand high box accessories. Different flushing volumes are used for urine and urine, which can save up to 50% of water.

4. Use the "micro-spray system" to water the lawn. Micro-spraying saves 80% of water than flood irrigation and 50% of water than ordinary large-spraying. It has low cost and long service life.

5. The bathroom shower uses a "diaphragm foot shower". This shower fundamentally eliminates dripping and leaking, and the use effect is very good.

6. The swimming pool uses circulating water treatment equipment, so there is basically no need to replenish water.

7. Construction of "Reclaimed Water Treatment Project". Collect dirty water such as bathing sewage, laundry water, vegetable washing water, and flushing water, and undergo a series of steps such as filtration, sedimentation, biochemistry, and disinfection through the reclaimed water treatment station to turn it into a water source that can be reused. This treated water can be used to water green spaces, flush cars, spray playgrounds, flush toilets, etc. The average unit does not spend a lot of money to build a water treatment station, but the results are great. Especially today when water costs are rising day by day, it is indeed very cost-effective.

Family water-saving plan

We have designed a water-saving plan for families. After implementing this plan (or taking measures in this plan), we guarantee that you will receive a lot of benefits. The good water-saving effect can save you energy, reduce expenses, and reduce unnecessary troubles (such as water leakage, noisy people, flooded furniture, etc.).

For families, there is generally no problem of wasting water casually. After all, you have to pay for it. The main problems are: first, the awareness of water saving is not strong; second, the use of water appliances is backward; third, they don’t know what water saver to use and where to buy it. Here are some things to know about household water-saving appliances.

1. Toilet water saving: According to statistics, toilet water accounts for more than 50% of household water consumption. The main reason is that the structure is unreasonable and water is wasted.

According to the capacity, there are three types of toilets: 15 liters, 9 liters, and 6 liters. Countries with 15 liters have explicitly eliminated them. Now they are vigorously promoting 6-liter toilets. However, because the 6-liter toilet is a systematic project (involving the structure of the seat and the smoothness of the material) , inclination, etc.), it can be used in new buildings, but the renovation of toilets in old buildings cannot. Because the water consumption is small, it is difficult to flush clean, but it brings trouble to users. According to the structure, it can be divided into vertical type, flip type, siphon type, hydraulic type, pressure difference type, etc. The straight-down type has been eliminated by the state, and now most users use the flip-up type. New toilets have siphons combined with pressure differences, and toilets with separate toilets and urinals. The large water stall is used for defecation and the small water stall is used for urination, thereby achieving the purpose of saving water. So what should you do to save water in the toilet?

1. Replace the whole set with new ones. It is recommended to choose a two-speed siphon differential pressure water-saving toilet. This kind of sanitary ware not only saves water, but is also very convenient to use. Use the large toilet for defecation and the small toilet for urination. It can be used by the elderly and children. This method is more expensive. We can do it for about 400 yuan and install it at your doorstep.

2. The water tank and seat bucket are not replaced, only the water tank accessories are replaced. This is also a good idea. The Liwufang brand is 48 yuan, and the Zhonghuading brand is 88 yuan. They are also patented products. They are divided into toilet and urinary products, saving 50% of water, and have a three-year warranty. They are also worth replacing.

3. Don’t change anything, just take some small measures to get twice the result with half the effort. ⑴ Add a small plastic-coated spring to the flap. This not only makes the flap more airtight, but also allows you to control the water consumption. If you want to use half a box, use half a box. If you want to use one box, use one box. According to calculations, the usage is more economical. Water spring can save 20-40% of water. Don’t underestimate this small spring. It is also a patented product. It only costs 3 yuan to solve the problem. It only takes half a minute to install. (2) Fill water cups and Coke bottles with water and put them in the water tank. I don’t need to tell you the truth behind this. You will also understand, of course, bricks can also be used.

2. Faucets save water. The old-fashioned rotary faucet must no longer be used. It wastes water and is laborious, and the valve stem is prone to water seepage, making it dirty, not to mention how uncomfortable it is.

Using ceramic chips, variable pitch, self-closing and other leak-proof, high-tech faucets. Not only do these faucets not leak, they have a long service life, and variable pitch, self-closing, etc. also have the function of opening. It has the characteristics of short closing time, prevention of water loss, and self-closing without water pressure, and has a warranty period of more than three years. What should I do if I forget to turn off the faucet after the water is cut off? Furniture is flushed, electrical appliances are soaked, and neighbors come to see me. It’s annoying. If you install a safety self-closing faucet, you don’t have to worry. It will automatically close when it is deactivated, and not a drop of water will flow out when it comes. With it, you never have to worry about water flooding the mountain, and it can be opened 360 degrees and can be turned at any angle, which is very convenient and hygienic. There is also a variable pitch faucet. With this kind of faucet, the trickle flow and line flow mentioned before are impossible, but I am sorry for those friends who steal water through this method, and it closes quickly. It's only 0.16 seconds (others take 1-3 seconds), don't underestimate this time, the water saved over time is considerable.

3. Air conditioning and water regulation. Air conditioners can also save water, don’t get me wrong? Yes, but it should be "making" water. Listen: The summer is scorching hot, and every air conditioner is running. The poor neighbors are suffering, and they can’t sleep due to the beeping. The air conditioner dripping problem has also been a problem that has troubled us for many years. If we lead the drain pipe into the house and connect a bucket, the problem is solved, and the amount of water is still considerable. One liter of water is collected in 2 hours. This water can be used to water flowers, wash hands, and flush toilets. The neighbors were also happy. Isn't that a good idea.

Water-saving slogan:

1. Let us save every drop of water and don’t let our faucets cry any more.

2. Water is limited. If people waste water every day, the earth will one day be without a drop of water. Water is precious. If there is no water on the earth, animals, plants and us humans will die of thirst. Water should be cherished by us. In my mind, water is as precious as pearls, beautiful and crystal clear. How can we bear to watch water being wasted drop by drop? Students, let us be water-saving guardians together!

3. Without water, our world will become a desert without flowers, grass, or trees, and people will die.

If you save water, people will live happily on the earth, and there will be one less possibility of extinction. Please save water!

4. Look! There is a faucet crying sadly, let it be happy, let it smile! Just remember to turn off the faucet every time and you can do it!

5. Water is life, please save water.

6. Save water. Saving water starts with me.

7. Saving water is everyone’s responsibility.

True love for home, save water first

Environment is the main axis of life, water is the lubricant of the axis, inseparable

The foundation of survival--- - Water and the environment

Everyone is paying attention, and every sentence is the truth

Without water, how can we talk about the environment

I hope these headlines can bring you some inspiration !

Since humans entered the 21st century, we have to face the fact that available freshwater resources are becoming increasingly scarce. In the process of building a moderately prosperous society in an all-round way, whether the development concept of sustainable utilization of water resources can be established is a major issue related to my country's social and economic development and the survival of future generations. Increasing law enforcement and paying comprehensive attention to water resources should be urgent issues before us.

Weather, climate and water resources

Water is an important natural resource on which life depends. Most of the water needed by living things on earth comes from rivers, lakes, glaciers and oceans. The main source of supply for these valuable freshwater resources is atmospheric precipitation. In the climate system, the water cycle is one of the most important material cycles. Weather, climate and water cycles are conducive to human survival and development under normal circumstances. This is what people often call good weather.

How can we expect good weather? Ecologists have come to the conclusion after research: If a country's forest coverage reaches about 30%, major natural disasters rarely occur; if it reaches 40%, it will have a better ecological environment; if it reaches 40%, it will have a better ecological environment; Reaching 60%, this country will be prosperous, beautiful and rich.

The severe situation facing my country’s water resources

With the continuous intensification of human activities and the rapid development of population and urbanization, the situation facing water resources is becoming increasingly severe. As early as 1972, the United Nations' First Conference on the Human Environment issued a warning: "Water will cause serious social crises." More than 30 years have passed, and the water resources problem has not only not been fundamentally solved, but has become increasingly serious.

At present, the contradiction between water supply and demand in my country is facing a very severe situation. Among more than 660 cities across the country, there are more than 400 cities that are short of water, of which 108 are seriously short of water. The country produces nearly 80 billion kilograms of grain every year due to water shortage. Economic losses caused by water shortage reach 200 billion yuan every year. my country's per capita water resources are only 1/4 of the world average and 1/5 of the United States. China ranks 110th in the world and is one of the countries with the poorest per capita water resources in the world. Water shortage has become a major constraint affecting my country's economic development, people's lives and environmental improvement.

What is not optimistic is that while we are short of water, our country's soil erosion and water resource pollution are still serious. Water and soil erosion has led to further deterioration of the ecological environment. The deterioration of the ecological environment has caused water resources and the water environment to fall into a vicious cycle. The strange circle.

According to the analysis of "China Water Supply and Demand in the 21st Century" by the Ministry of Water Resources, in 2010, the total water demand for my country's industry, agriculture, life and ecological environment was 698.8 billion cubic meters in a moderate drought year, and the total water supply was 667 billion cubic meters. , water shortage of 31.8 billion cubic meters. This shows that our country will begin to enter a period of severe water shortage after 2010.

From the perspective of population growth, my country's population will reach 1.6 billion around 2030, and the per capita amount of water resources will be reduced by 1/5 from the current level, to about 1,700 cubic meters; from the perspective of economic growth , by the middle of the 21st century, the GDP will increase by more than 10 times, urban and industrial water use will increase significantly, and waste and sewage discharge will also increase accordingly. The task of increasing revenue, reducing expenditure, and protecting is very arduous; from the perspective of urban development, by the middle of the 21st century, my country's urbanization rate will reach 70%, and the contradiction between urban water supply and demand will become more acute; from the perspective of agricultural production, especially grain production, by 2050, my country's grain output will increase by more than 140 billion kilograms compared with now, which means that the total amount of agricultural irrigation Water consumption must increase, especially in northern regions where the water resource situation will become more severe.

Save water and control water in accordance with the law

Water resources are important natural resources, indispensable and irreplaceable material resources for human survival and social development. Faced with the very severe situation of water supply and demand in my country, law enforcement must be stepped up to solve the problem of water resources, starting from the following three links.

First of all, we must save water in accordance with the law. This is the most effective measure to solve the current contradiction between supply and demand. Article 8 of the new "Water Law" revised and promulgated in August 2002 clearly stipulates: "The state strictly implements water conservation, vigorously promotes water conservation measures, promotes new water-saving technologies and processes, and develops water-saving industry, agriculture and service industries. Establish a water-saving society.” The slogan of water conservation has been raised for many years, but it lacks binding force and the results are not obvious. It is time to enter an era of water conservation for all people and water conservation in accordance with the law. Carry out water-saving education throughout society and use economic leverage to carry out mandatory water-saving. Units and individuals who waste water resources wantonly shall be punished in accordance with the law and effectively establish a water-saving society.

Secondly, we must pay attention to the development and utilization of atmospheric water from a strategic perspective. Asking for water from the sky is another way to solve the water crisis. Artificial rainfall enhancement in my country began in the late 1950s. At present, artificial rainfall enhancement work has been carried out in most areas of our country. From 1995 to 2003, 23 provincial governments across the country organized more than 4,230 artificial rainfall enhancements, with a total of 9,881 flight hours. The rainfall enhancement area reached more than 3 million square kilometers, and the precipitation increased by about 210 billion cubic meters. Drought has played a significant role in adversely affecting the national economy. Third, building a good ecological environment is the long-term and fundamental solution to solve the problem of water resources. The destruction of forests and vegetation is an important factor leading to water shortages. Over the past half century, our country has consumed 8.6 billion cubic meters of forest resources, which is equivalent to cutting down all the forests in the country. Today, the per capita forest area and stock volume are only 20% and 12% of the world average respectively. The large-scale blind utilization of ecological resources has caused a sharp decline in the quality of my country's ecological resources. Rivers have dried up, lakes have shrunk, and water resources conservation and regulation capabilities are seriously insufficient. The three major disasters of flooding, drought and desertification have become a serious threat to the Chinese nation.

The water crisis has become a bottleneck affecting the development of our national economy and will threaten the development of the Chinese nation. In order to save our common homeland and for our own survival and development, in the face of the increasingly severe water resources crisis, increasing law enforcement and using legal means to strictly restrict and govern should be an effective breakthrough in solving water resources problems. .
