How to protect the environment?

Environmental protection is a general term for all human activities that use the theories and methods of environmental science to coordinate the relationship between humans and the environment, solve various problems, and protect and improve the environment. Including, taking administrative, legal, economic, scientific and technological measures to rationally utilize natural resources, prevent environmental pollution and damage, in order to maintain and develop ecological balance, expand the reproduction of useful natural resources, and ensure that human beings social development. Environmental protection covers a wide range and is highly comprehensive. It involves many fields of natural science and social science, and has its own unique research objects. Environmental protection includes at least three levels of meaning:

Protection of the natural environment

Preventing the deterioration of the natural environment. Including: protection of green mountains, green water, blue sky and sea. This involves no private mining (mines) and indiscriminate felling (trees), no random discharge of (sewage) (sewage), no excessive grazing, no excessive land reclamation, no over-exploitation of natural resources, no destruction of the ecological balance of nature, etc. wait. This level is macroscopic and can only be solved by governments at all levels exercising their functions and regulating.

Protection of human residence and living environment

Make it more suitable for the needs of human work and labor. This involves all aspects of people's clothing, food, housing, transportation, and play, which must comply with scientific, hygienic, healthy, and green requirements. This level is microscopic and must rely on citizens' conscious actions, government policies and regulations as guarantees, and community organizational education for guidance. Only workers, peasants, soldiers, students, and businessmen from all walks of life must work together to manage the problem.

Protection of organisms on earth

Preservation of species, conservation of plant vegetation, return of animals, biodiversity, and the combination of genetically modified organisms to protect endangered organisms

Reasonable and prudent use, special and special protection of endangered species, recovery of extinct species, expansion of habitats, harmonious coexistence between humans and organisms, not bullying other species, etc. The relationship between these three levels is: I am in you, you are in me, each has its own focus but is unified. The three are not contradictory, let alone antagonistic. As citizens, our protection of the living and living environment is to indirectly or directly protect the natural environment; if we destroy the living and living environment, we will directly or indirectly destroy the natural environment. As a government, we must not only focus on macroscopic protection, but also start from the microscopic level, mobilize and educate the masses, and make environmental protection a conscious action for citizens. After the United Nations Conference on the Human Environment in 1972, the term "environmental protection" was widely used. For example, the former Soviet Union gradually changed the traditional term "nature protection" to "environmental protection"; China proposed the policy of "comprehensive utilization" of industrial waste in 1956, and proposed the concept of "three wastes" treatment and recycling in the late 1960s. By the 1970s, the more scientific concept of "environmental protection" was used. According to the "Environmental Protection Law of the People's Republic of China", the content of environmental protection includes the protection of the natural environment and the prevention and control of pollution and other public hazards. That is to say, we must use the theories and methods of modern environmental science to make better use of resources while deeply understanding and grasping the root causes and hazards of pollution and damage to the environment. We must protect the environment in a planned way, restore ecology, and prevent the deterioration of environmental quality. Control environmental pollution and promote the coordinated development of humans and the environment. It is relatively late for China to attach importance to environmental protection. There is still a gap in the attention paid by governments at all levels. There are not many governments that can be called environmentally friendly. Therefore, it is too early to talk about environmental protection.

Edit the scope of this paragraph

Including the protection of the earth, the protection of space and the universe, and the maintenance of the living environment. Land (terrain, landforms, etc.), atmosphere, water, living things (human beings, forests, plants, animals, etc.), sunlight, the natural and artificial external world as a whole. Natural and cultural heritage.

Governance and Protection of the Earth

The reason why the environmental protection of the earth puts governance in the front and protection in the back is because the land is already polluted, so we want to emphasize governance and protection at the same time. Strengthen the management of polluted land (land, mountains, continental shelves) and restore the original source

Atmosphere management and protection

Limit, reduce emissions, and purify the atmosphere, using natural + artificial methods

Water Management

Since social production and life are closely related to water, water hunger, water shortage, water shortage, and water pollution are the key points of "water". "Treatment" is the most important focus of the water family. Therefore, the field of water treatment involves a wide range of applications and constitutes a huge industrial application. There is a tendency to exceed "natural water".

Water treatment methods include: (1) sediment filtration, (2) hard water softening, (3) activated carbon adsorption, (4) deionization, (5) reverse osmosis, reverse osmosis; (6) ultrafiltration method, (7) distillation method, (8) ultraviolet disinfection method, (9) biochemical method, etc., and the most novel (10) forward osmosis method, a new creation of human beings in natural purification methods. The natural "forward osmosis method" reduces secondary and tertiary pollution, energy consumption, and warms up the future of hope. Promote negative growth in environmental water costs.

Edit measures in this paragraph

1. Air conditioners are 26 degrees Celsius in winter and 18 degrees in summer, saving hundreds of millions of degrees nationwide. The air conditioner temperature in winter is adjusted to 18 degrees Celsius or below. If you feel a little cold, you can put on more clothes. Such a simple move can save electricity, thereby reducing greenhouse gases such as carbon dioxide emitted by coal-fired power generation and slowing down climate warming. In summer, the air conditioning temperature is adjusted to 26 degrees or above. The air-conditioning load in big cities accounts for about 40%-50% of the maximum power supply load in midsummer. Increasing the air-conditioning temperature from 22-24℃ to 26-28℃ can reduce the power load by 10%-15% and reduce the power load by 400-600 million yuan. power consumption above degrees. Sweating in summer is good for health, as it can enhance metabolism, regulate endocrine function and promote autoimmunity. 2. Replace light bulbs with energy-saving lamps to save nearly 80% of electricity consumption. Replace ordinary light bulbs at home with energy-saving light bulbs, and purchase products that have passed the "National Energy-Saving Product Certification". You can tell by whether there is a "festival" mark printed on it. Under the same luminous flux conditions, energy-saving lamps can save 80% of electricity energy than incandescent lamps. The cost of purchasing energy-saving lamps can be recovered from the electricity bill savings in (8 to 10) months. 3. Classify garbage, do not litter, recycle and regenerate. About 50% of the garbage is biological organic matter, and about 30%-40% has recyclable value. In 2000, the six major amounts of recyclable waste produced in China were: 41.5 to 43 million tons of scrap steel, 1 to 1.2 million tons of nonferrous metal scrap, 850,000 to 920,000 tons of waste rubber, 2.3 to 2.5 million tons of waste plastics, and 2.3 million to 2.5 million tons of waste plastics. There are 10.4 million tons of glass and 10 to 15 million tons of waste paper. At present, the value of usable but unused waste in China reaches 25 billion yuan every year. About 3 million tons of scrap steel and 6 million tons of waste paper are not recycled. The recycling rate of waste plastic is less than 3%, and the recycling rate of rubber is 31%. The more than 6 billion used dry batteries thrown away every year alone contain more than 70,000 tons of zinc and 100,000 tons of manganese dioxide. 4. Turn off the power without using electrical appliances. The 10% energy saving can be seen. For various electrical appliances in homes and offices, such as TVs, computers, etc., please turn off the power when not in use. In standby mode, the TV consumes an average of 8.07 joules per hour, the air conditioner consumes 3.47 joules, the monitor consumes 7.69 joules, the PC host consumes 35.07 joules, and the range hood consumes 6.06 joules. The small act of turning off the power can save you money on your energy bill and help the environment. 5. Encourage high-energy-consuming enterprises to install energy-saving facilities. In the past decade, due to energy shortages, energy-saving work has been further developed. Various new, energy-saving and advanced furnace types are becoming more and more perfect, and the use of high-quality insulation materials such as new refractory fibers has significantly reduced the heat dissipation loss of the furnace. The use of advanced combustion devices enhances combustion, reduces the amount of incomplete combustion, and makes the air-fuel ratio more reasonable. However, the technology to reduce exhaust heat loss and recover flue gas waste heat is still progressing slowly. In order to further improve the thermal efficiency of the kiln and achieve the purpose of energy saving and consumption reduction, recovery of flue gas waste heat is also an important way to save energy. There are usually two methods for recovering flue gas waste heat: one is to preheat the workpiece; the other is to preheat air for combustion. The flue gas preheating workpiece needs to occupy a large volume for heat exchange, which is often restricted by the working site (this method cannot be used in kilns that are used intermittently). Preheated air combustion is a better method. It is generally configured on the heating furnace. It can also strengthen combustion, speed up the heating rate of the furnace, and improve the thermal performance of the furnace. This not only meets the requirements of the process, but also achieves significant comprehensive energy-saving effects in the end. In addition, preheaters for preheating air have been used in industrial furnaces in China since the 1950s. The main forms are tubular, cylindrical radiant and cast iron block heat exchangers, but the exchange efficiency is low. In the 1980s, domestic heat exchangers such as jet type, jet radiant type, and compound table type were successively developed to mainly solve the problem of medium and low temperature waste heat recovery. Remarkable results have been achieved in recovering flue gas waste heat below 100 degrees, improving heat exchange efficiency.

However, at high temperatures, the material of the heat exchanger is limited, the service life is short, the maintenance workload is large, or the cost is high, which affects its popularization and use. At the beginning of the 21st century, Gongyi City, Henan Province, China finally developed the Ronghua ceramic heat exchanger. Its production process is basically the same as that of kiln furniture. Thermal conductivity and oxidation resistance are the main application properties of the material. Its principle is to place the ceramic heat exchanger close to the flue outlet in a place with higher temperature, without the need for cold air and high temperature protection. When the kiln temperature is 1250-1450°C, the temperature at the flue outlet should be 1000- 1300℃, the waste heat recovered by the ceramic heat exchanger can reach 450-750℃. The recovered hot air is sent into the kiln to form a mixed gas with the gas for combustion, which can save 35%-55% of energy, thus directly reducing production costs. Increase economic benefits. Ceramic heat exchangers have been well developed under the limitations of metal heat exchangers because they can better solve problems such as corrosion resistance and high temperature resistance, and have become the best heat exchangers for recovering high-temperature waste heat. After years of production practice, it has been shown that ceramic heat exchangers are very effective. Its main advantages are: good thermal conductivity, high high temperature strength, good oxidation resistance and thermal shock resistance. It has long service life, low maintenance, reliable and stable performance, and easy operation. It is currently the best device for recovering high-temperature flue gas waste heat. At present, ceramic heat exchangers can be used in major thermal kilns in metallurgy, non-ferrous metals, refractory materials, chemicals, building materials and other industries, and are making great contributions to the world's energy conservation and emission reduction.
