Composition: Research on how to save water in my family.

For a long time, people generally believe that water is "inexhaustible". If you don't know how to cherish it, you will waste it. In fact, water resources are increasingly scarce, and the urban water supply work in our city is struggling on the edge of serious water shortage, and tap water is hard to come by.

People can't live without water for a day. Water is the source of life. Cherishing water means cherishing your own life! Here, we introduce some water-saving common sense in daily life:

Brush your teeth/teeth

Waste: continuous drainage for 30 seconds, using about 6 liters of water.

Water saving: cups are connected with water, 3 cups use 0.6 liters of water. A family of three can save 486 liters of water twice a day.

wash clothes

Waste: The washing machine needs about 165 liters of water each time while filling water.

Water saving: the washing machine adopts the washing-dehydration-water injection-dehydration-water injection-dehydration mode, and the water consumption is 1 10 liter each time, which can save 55 liters and 220 liters each time.

In addition, centralized laundry can reduce the number of laundry; Hand washing is advocated for small pieces and a small amount of clothes, which can save a lot of water; Too much detergent will waste a lot of water.

have a bath

Waste: A long uninterrupted water shower will waste a lot of water.

Too much bath water, or even overflow, or open the water plug and inject water at the same time, the waste will be amazing.

Water saving: intermittent water shower (such as pedaling, induction, etc.). ). Turn off the water in time when scrubbing. Avoid taking a long shower.

The water after bathing can be used for washing clothes, washing cars, flushing toilets and mopping floors.

cook

Waste: the tap was left on for a long time. Boiling water for too long, a lot of water vapor evaporates. Rinse vegetables and fruits with tap water.

Water saving: oil stains on cookware and tableware can be wiped off with paper before washing, which can save water.

Control the flow of the faucet, and change the uninterrupted flushing into intermittent flushing.

wash a car

Waste: Rinse with water pipe for 20 minutes and use about 240 liters of water.

Water saving: 3 barrels of water are needed for car washing, and the water consumption is about 30 liters. Wash the car with car wash water and car wash water. Rinse with a water-saving spray gun. Use mechanical automatic car washing, car washing water treatment recycling.

Small ways to save water:

Saving water is beneficial to the present and will make great contributions to the future. After discussion, the students came up with some ways to save water in life:

1. Washing vegetables with rice-washing water and then with clear water not only saves water, but also effectively removes pesticide residues on vegetables;

Second, wash the mop, sweep the floor, and then flush the toilet. The second washing water for washing clothes cleans doors and windows, furniture, shoes and socks, etc.

Third, flush the toilet after urinating, try not to open the big water pipe for flushing, and make full use of the used "dirty water";

4. Sprinkle water on the indoor and outdoor ground in summer to cool down, try not to use clear water, and use washing water after washing;

5. When cleaning bicycles and family cars, don't wash them with water, but wipe them with a wet cloth. If it is too dirty, wash it with the water left over from washing clothes.

6. Flushing the toilet: If you use water-saving equipment, you can save 4-5 kilograms of water each time;

Seven, family watering flowers, appropriate use Taomi water, tea, laundry water, etc. ;

Eight, household washing towels, small objects, fruits and other small amounts of water. It is advisable to use a basin to hold water instead of turning on the tap to flush it;

9. Washing the floor: scrubbing with a mop can save more than 200 kilograms of water than washing each household with a faucet;

Ten, faucet used for a long time leaks. The rubber cover of the small penicillin bottle can be cut open to ensure no water leakage;

1 1. Adjust the floating ball in the toilet water tank down by 2 cm, saving nearly 3 kg of water each time; If you use it four times a day at home, you can save 4380kg of medicine a year.

Twelve, washing vegetables: a pot of a pot, do not run the faucet, a meal can save 50kg；;

Sixteen, car washing: scrubbing with a rag can save at least 400kg. Compared with washing with a faucet, the water consumption is much less each time;

◆ Speech 1

Student: You must have seen such a public service advertisement: there is a faucet on the TV screen, which is dripping with difficulty. The dripping speed became slower and slower, and finally the water was used up. Then a pair of eyes appeared on the picture, and a tear flowed out from it. Followed by this sentence: "If human beings don't cherish water, then the last drop of water we can see will be our own tears."

Water is the source of life. If there were no water on the earth, Mother Earth would not give birth to our descendants. Because the earliest primitive life was first bred in the ocean and gradually extended to the land. Therefore, water is the cradle of life. The survival and development of human beings are also inseparable from water. Because we have to drink water every day, food growth can not be separated from water, and industrial production can not be separated from water. Water is also the "air conditioner" of nature. How happy it would be to have a rain in the hot summer when people feel unbearable heat! Walking by the sea, the sea breeze blows gently, sweeping away the hot and irritable mood; When the cold winter comes, the seawater continuously transfers the stored heat to the surrounding land ... all these are the functions of water.

Is water really not worth it? Is it really unimportant to save water? 93% of the water in the world is salty and can't be drunk. Fresh water accounts for only 7%, and drinking water accounts for only 0.8%. The world's 5 billion people depend on drinking this 0.8% fresh water. Look, how precious water is! Although China is rich in water resources, there are few available fresh water resources, and with the development of industry, water pollution has become a serious problem, and many industrial wastewater stinks. What a terrible thing!

March 22nd is World Water Day. Every year on this day, all countries in the world will publicize that everyone should cherish water resources and protect the water of life. In fact, it is not only this day, but every day in our life should cherish every drop of water and cherish the water of life with practical actions! Water exists in the sky, underground, rivers and lakes. For saving water, students always feel less important than saving other things. Some students turn on the tap, wash their feet and wash their children. Some students don't drink boiled water, but drink tap water with their mouths to the faucet. The sound of water doesn't hurt at all.

Although three liters of water per person per day can sustain life, in fact, every urban resident has to cook, wash clothes and wash vegetables every day ... everything can't be separated from boiling water, and it takes hundreds of liters of water. In addition, agriculture and industrial production are inseparable from water. For example, steelmaking and steel rolling only need water cooling; In order to maintain a certain temperature and humidity, the textile workshop needs to adjust the moisture; Building construction is inseparable from water; Paper-making, power generation ... Food, clothing, housing and transportation, which can be separated from boiling water? People can live without food for several days, but they can't live without water for several days. Humans can't live without water, which shows how important it is to save water.

Then how do we get the tap water we use every day? It is the worker's uncle in the waterworks who introduces river water or groundwater into the factory, puts the water into the sedimentation tank, adds medicine for disinfection and sterilization, and removes harmful substances and impurities. In this way, many pipelines were buried underground. These pipes are tied up one by one, which is the result of the hard work of many waterworks workers and uncles day and night. When we turn on the tap, we should think that the bread in the water contains the hard work of many workers' uncles!

Students, do you know the meaning of saving water? Please look at an account: one ton of water can supply about 150 kg of steel, generate electricity 1000 kg per hour, produce 500 kg of chemical fertilizer, weave 220 meters of cloth and grind 34 bags of flour. "Dripping water becomes a river", if everyone saves water, every little makes a mickle, they can play a greater role!

Students, we are small masters of the country, and we should develop good ideas and habits of saving water from an early age. Whether at school or outside school, we should pay attention to saving water. We should be a good boy who saves water by taking practical actions.

◆ Speech 2

Have you ever seen such an advertisement? There is a faucet on the TV screen, dripping with difficulty, and the dripping speed is getting slower and slower. Finally, there are a pair of eyes, from which a tear flows out: "If human beings don't cherish water, then the last drop we see will be our own tears."

March 22nd is World Water Day. As we all know, water is the source of life, and China is one of 12 water-deficient countries in the world. With the development of industry, a large number of industrial wastewater and urban sewage are discharged into rivers, lakes and oceans, and rivers are polluted. Not only that, but also the waste of water is very serious.

Look at the water habits in our daily life: some children often forget to turn off the tap after washing their hands and let the spray run away; Some people have played "water fights" and played water games after going to the toilet; Some even use drinking kettles as "water guns" and sprinkle water columns on the ground. Some students stuffed debris into the toilet water pipe, which caused the blockage and the water overflowed the whole toilet! I believe that such behavior must be unacceptable to students, so we can supervise and remind each other and gradually get rid of the bad habit of wasting water.

Students, let's firmly remember 3.22 World Water Day, take active actions, publicize the importance of water saving, consciously protect and save every drop of water, raise the awareness of water saving of the whole people with our practical actions, and make due contributions to protecting our precious water resources and social ecological environment.

◆ Speech 3

Save water and start from scratch. Maybe students will think that a drop of water is insignificant. However, recently I saw a set of data that was very enlightening: according to scientific determination, if "dripping water" keeps flowing, 3.6 kilograms of water can be collected within 1 hour and 2.6 tons of water can be collected within 1 month. This amount of water is enough for a person to meet his needs for half a year. Obviously, every drop of water should not be wasted.

Water has a great influence on the earth and its residents, and it is indispensable for families, factories and rural people. More than two-thirds of the human body is water, so we should drink water every day to replenish the water lost during sweating and breathing and keep healthy. A person can't live without drinking water for more than four days, but it takes one ton of water a year to maintain a healthy life. I suddenly realized what a philosopher said: If we don't save water now, the last drop of water in the world will be our human tears!

As a student, although we can't do great things to save water, we can start from ourselves. For example, when we see someone wasting water, we can actively promote the significance of saving water; Seeing some faucets dripping, we can walk over and close them behind us; Reuse water resources, collect your own face washing water, wash clothes and flush toilets. According to statistics, if 65.438+300 million people in China save a drop of water each, 45 tons of water will be saved! What amazing data! Isn't the Yangtze River and the Pentium Yellow River associated with the motherland also made up of water droplets?

Students, let's join hands, start from me and now, carry forward the traditional virtues of the Chinese nation, save every drop of water and work together to build our beautiful home!

◆ Speech 4

Our earth is a blue water polo, covered with water; But most of them are salt water, which can't be drunk directly, and there is not much fresh water that can really be used. For example, in the big water tank of the earth, there is only one spoonful of water available. At present, the population of more than half of the countries in the world is about 654.38+0.5 billion, of which 450 million people in 29 countries are in a state of water shortage. The word "water is as expensive as oil" is a metaphor, but it has become an irrefutable reality in many parts of the world.

As early as 1977, the United Nations held a conference on water resources, which issued a solemn warning to the whole world: water will soon become a profound social crisis, and the next crisis after the oil crisis will be water. The era of regarding water as inexhaustible has passed, and the era of regarding water as a valuable resource has arrived. China ranks only 84th in the world in per capita possession, and is one of 13 water-poor countries in the world. 300 cities in China are short of water, nearly 50 cities are seriously short of water, and 14 coastal cities are short of water.

China is also facing a serious water crisis, and many places are short of water. Please listen to these figures: 1988 In summer, Wuhan residents forcibly opened 50 fire hydrants to get water. 1989, Xi' an, once known as the "Eight Rivers in Chang 'an", had a water-cut area of 27 square kilometers. According to the relevant water resources report, the groundwater level in Kunming, Yunnan Province, which is relatively rich in water resources, is declining at an average annual rate of 0.1m ~ 0.31m. Can't these terrible facts and amazing figures attract our attention?

However, there are still various phenomena of wasting resources around us. On one occasion, several big brothers in our school turned on the tap to let students wash their hands and fought with water. Seeing this, I quickly went forward and turned off the tap. However, several brothers pushed me away and said, "It's none of your business, go away!" " . According to my observation, a similar phenomenon occurs in our life: in broad daylight, the office lights are on; In cooler autumn, air conditioners and fans are turning; Water from public taps often drips. When will these phenomena disappear? Do we have to wait until water resources are scarce and exhausted before we come back to talk about saving?

"Saving water" is not to limit people's use of water, let alone to prevent it. In fact, saving water is to make people use water reasonably and efficiently. Saving water does not affect our quality of life. Everyone has the obligation to cherish resources and correct others' waste of water resources. The view that "as long as I pay the water fee, I can squander it at will, and wasting water is my own business, and others can't control it" is wrong, and the view that "water is only 70 cents, which is very cheap, and it doesn't matter if it is used too much" is even more harmful. Saving water is the responsibility of every citizen.

China's water law points out that water resources are owned by the state, that is, by the whole people. All countries in the world also stipulate that water is public property. Therefore, everyone should have a sense of public water. Power resources are also very precious, which embodies the efforts of many people. Everyone should cherish and save water and oppose water pollution and waste.

"Look at the former sages and their families, they became thrifty and were defeated by luxury." Running a school with diligence and thrift is a public morality and a virtue.

Students, uncles and aunts, let's take action. Let's cherish resources and strive to build a conservation-oriented society.
