Environment Protection (Environment Protection) Environmental protection (referred to as environmental protection) is caused by the serious environmental pollution problem caused by industrial development, which first attracted the attention of industrialized countries. Environmental protection

Use national laws and regulations and public opinion propaganda to make the whole society pay attention to and deal with pollution problems. 1. The soil is damaged. According to reference news reports, the fertility of arable land is declining in 110 countries (~1 billion people). In Africa, Asia and Latin America, soil erosion is very serious due to the disappearance of forest vegetation, over-exploitation of cultivated land and over-grazing of pastures. The exposed land became fragile and could not withstand the erosion of wind and rain for long. In some places, annual soil loss can reach 100 tons per hectare. Excessive use of fertilizers and pesticides, the fall of toxic dust associated with air pollution, the spraying of slurry and the dumping of hazardous waste all contribute to the generally irreversible contamination of the land. Soil refers to the loose surface layer on the land surface that is fertile and capable of growing plants. Its thickness is generally about 2 m. Soil not only provides mechanical support for plant growth, but also provides water, fertilizer, air, heat and other fertility elements needed for plant growth and development. In recent years, due to the rapid growth of population and rapid industrial development, solid waste has been continuously piled and dumped on the soil surface, harmful wastewater has continued to seep into the soil, and harmful gases and flying dust in the atmosphere have continued to fall into the soil with rain, leading to soil pollution. . All substances that hinder the normal function of soil, reduce crop yield and quality, and indirectly affect human health through food, vegetables, fruits, etc. are called soil pollutants. 2. Climate change and energy waste The greenhouse effect seriously threatens all mankind. According to 2,500 representative experts, sea levels will rise and many densely populated areas (such as Bangladesh, coastal areas of China, and most islands in the Pacific and Indian Oceans) will be submerged. Rising temperatures will also have serious impacts on agriculture and ecosystems. It is expected that energy consumption in Asia and the Pacific will double from 1990 to 2010, and energy consumption in Latin America will increase by 50%-70%. Therefore, the transfer process of energy-saving technologies should be strengthened between the West and developing countries. In particular, we should use economic incentives to enable industrialists to develop technologies that improve the efficiency of industrial resource utilization. 3. Biological diversity decreases. Natural areas are becoming smaller due to urbanization, agricultural development, forest loss and environmental pollution, leading to the extinction of thousands of species. Because the extinction of some species will lead to the disappearance of many molecules that can be used to make new drugs, it will also lead to the disappearance of many genes that can help crops overcome harsh climates, and even cause plagues. 4. Reduction of forest area. In recent decades, the forest area of ??tropical countries has also declined seriously. Between 1980 and 1990, 150 million hectares of forest disappeared in the world. According to the current rate of forest area reduction, in 40 years there will no longer be a tree in some Southeast Asian countries. 5. Freshwater resources are threatened. Experts estimate that a quarter of the world will be chronically short of water from the beginning of the next century. Remember, we cannot create water, we can only try to protect it. 6. Chemical pollution. Millions of chemical compounds produced by industry are found in air, soil, water, plants, animals and humans. Even the ice caps, the last large natural ecosystems on Earth, are contaminated. Those organic compounds, those heavy metals, and those toxic products are all concentrated in the entire food chain, and will eventually threaten the health of animals and plants, cause cancer, and weaken soil fertility. 7. Chaotic urbanization. By the end of this century, there will be 21 big cities in the world, and living conditions in big cities will further deteriorate: overcrowding, polluted water, poor sanitation, and no sense of security. The disorderly expansion of these big cities has also harmed nature. district. Therefore, unrestricted urbanization should be seen as the new evil of civilization. 8. Over-exploitation of the ocean and pollution of coastal areas. Due to overfishing, the fishery resources of the ocean are declining at an alarming rate.

Therefore, many poor people who rely on seafood protein for a living are facing the threat of starvation. Substances such as heavy metals and organophosphorus compounds concentrated in fish species may cause serious health problems to fish eaters. Coastal areas are under tremendous population pressure. 60% of the world's population lives less than 100 kilometers from the sea. This overcrowding throws these often fragile places off balance. 9. Air pollution. The air in most big cities contains many pollutants from heating, transportation and factory production. These pollutants threaten the health of tens of millions of citizens and cause many people to lose their lives. Toxic gases are mainly carbon monoxide, sulfur dioxide, nitrogen dioxide and inhalable particles. 10. Polar ozone hole. Although people have signed the Montreal Protocol, ozone holes still form over the two polar regions of the earth every spring. The ozone layer in the Arctic has lost 20% to 30%, and the ozone layer in the Antarctic has lost more than 51%.

1. Soil destruction According to reference news reports, the fertility of arable land in 110 countries (***1 billion people) is decreasing.

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 (topography, 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 its origin.

Atmosphere governance and protection

Limit, reduce emissions, purify the atmosphere, use natural + artificial methods

Water governance

Because Social production and life are closely related to water. Water hunger, water shortage, water shortage, and water pollution are the focus of "water". "Water treatment" is the most important focus of the water family. Therefore, the field of water treatment The range of applications involved is very wide, forming 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 step 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 electricity 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 in your 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 electric 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 our country reaches 25 billion yuan every year, and 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 solid cost is expensive, 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 near 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 to recover 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.

Edit this paragraph New concept of environmental protection

3.22 is the world earth Daily life: People often describe certain pollution-free products as environmentally friendly products. Many products have passed environmental certification so that users can distinguish them. Such as environmentally friendly shopping bags, etc. Coordinated Development of Nature, Economy and Society The deterioration of the global environment has aroused widespread concern. As a result, environmental protection has increasingly attracted the attention of various countries. However, because environmental protection may have conflicts with economic development and social issues that are difficult to coordinate to a certain extent, in recent years, the understanding of the concept of environmental protection has become increasingly novel and reasonable. Environmental protection is to protect the environment for human survival from pollution and damage by taking administrative, legal, economic, scientific and technological measures, etc.; it is also to protect and improve the environment according to human wishes to make it better It is suitable for human labor and life and the survival of living creatures in nature, and eliminates adverse factors that damage the environment and endanger human life and survival. The problems to be solved by environmental protection generally include two aspects. One is to protect and improve environmental quality, protect human physical and mental health, and prevent the body from mutating and degenerating under the influence of the environment; the other is to rationally utilize natural resources to reduce or eliminate harmful substances. Substances entering the environment, as well as protecting the restoration and expanded reproduction of natural resources (including biological resources) to benefit human life activities. Of course, environmental protection must also consider economic growth and social development. Only coordinated development among them is the new concept of environmental protection in the new era.

The quality of environmental protection work is directly related to the stability of the country and is of great significance in protecting the reproduction of social labor force from destruction. With the deepening of human understanding of the environment, the view that the environment is a resource is increasingly accepted by people. Air, water, soil, mineral resources, etc. are the natural wealth of society and the material basis for development and production, and constitute the elements of productivity. Due to serious air pollution, air cans were once sold abroad; due to water pollution, climate change, and excessive extraction of groundwater, water shortages have occurred in many parts of the world; due to population growth, misuse of cultivated land, and desertification, land is scarce, and so on. From this we can see that failure to protect the environment and environmental resources will threaten the survival of human society and also affect the sustainable development of the national economy. At the beginning of this century, industrialized developed countries only focused on economic development and ignored environmental protection, pursuing economic development at the expense of the environment. When pollution becomes a public hazard, arouses strong opposition from the general public and affects the smooth development of the economy, it is forced to control it and pays a high price. Later generations called it a development path of "pollution first and treatment later". This development method will not only slow down the development of the national economy, but will even destroy the material basis for the development of the national economy. On the other hand, if human beings do not act in accordance with the laws of environmental science and wantonly destroy the ecological environment, they will inevitably suffer environmental retaliation. Statistics show that in 1950, Yunnan Province had a forest coverage rate of 50%, and experienced major floods and droughts every nine years on average. Due to deforestation and other damage, the forest coverage rate was only 24.9% in 1980, which affected the climate regulation effect. Between 1950 and 1980, 11 disasters occurred, causing serious damage to agricultural production. This is the revenge given to mankind by the environment.
