Born, the use of national laws and regulations and public opinion campaigns to make the whole society to pay attention to and deal with the problem of pollution. In 1962, American biologist Rachel Carson published a book called "Silent Spring", which explained the role of the pesticide DDT pollution and destruction of the environment, as a result of the book's warning, the U.S. government began to investigate the issue of highly toxic pesticides, and the establishment of the Environmental Protection Agency in 1970, the states have also passed a ban on the production and use of highly toxic pesticides of the law. As a result of this incident, the book is considered a landmark starting point for environmental ecology in the 20th century. The First United Nations Conference on the Human Environment was held in Stockholm, Sweden, from June 5 to 16, 1972, under the auspices of the United Nations, and the famous Declaration on the Human Environment was put forward, which was the beginning of the environmental protection cause that formally attracted the attention of the governments of all countries in the world. The Chinese government also participated in this conference. The cause of environmental protection in the People's Republic of China *** and the country also began in 1972, Beijing established the Guanting Reservoir Protection Office, Hebei Province established the Office of Three Waste Disposal *** with the study to deal with the Guanting Reservoir is located in Guanting Reservoir belonging to the Hebei Province of Shacheng pesticide factory pollution Guanting Reservoir problem, leading to the promulgation of Chinese laws officially prohibit the production and use of DDT throughout the country. Established in 1973 The Environmental Protection Office under the State Construction Committee was later changed to the State Environmental Protection Administration, a ministry directly under the State Council. In 2008, after the "two sessions", the SEPA was upgraded to the "Ministry of Environmental Protection". The Ministry of Environmental Protection (MEP) is responsible for the unified supervision and management of environmental protection throughout the country. Environmental protection bureaus (departments) have also been established in each province (city and district). The Environmental Protection Hotline 12369 and the online 12369 Center have been set up to receive reports from the public on environmental pollution incidents. The main responsibilities of the government's environmental protection departments are to implement policies on controlling pollutant emissions formulated by parliaments (people's congresses) at all levels, and to encourage the development of pollutant emission control technologies to control pollution and protect and improve the environment. Environmental protection, which is extremely important in our lives, is something we should do what we can to protect the environment! First, the soil has been damaged. According to Reference News, the fertility of arable land is decreasing in 110 countries (****1 billion people). In Africa, Asia and Latin America, soil denudation is serious due to the loss of forest vegetation
The loss of forest vegetation, overexploitation of arable land and overgrazing of pastures. The bare land has become too fragile to withstand long-term denudation by wind and rain. In some places, the annual loss of soil can reach 100 tons per hectare. Excessive use of chemical fertilizers and pesticides, toxic dust fallout associated with air pollution, mud being sprayed everywhere, and hazardous wastes being discarded everywhere are all polluting the land in a generally irreversible way. Soil is the loose surface layer on the land surface that is fertile and capable of growing plants, and is generally about 2 m thick. Soil not only provides mechanical support capacity for plant growth, but also provides fertility elements such as water, fertilizer, air and heat needed for plant growth and development. In recent years, due to the rapid growth of population, rapid industrial development, solid waste is constantly piled and dumped on the soil surface, harmful wastewater is constantly infiltrated into the soil, and harmful gases and drifting dust in the atmosphere are also constantly landed in the soil along with the rainwater, leading to soil pollution. All substances that hinder the normal function of the soil, reduce crop yield and quality, and also indirectly affect human health through food, vegetables, fruits, etc., are called soil pollutants. Second, climate change and energy waste The greenhouse effect is a serious threat to all mankind. According to 2,500 representative experts, sea levels are expected to rise and many densely populated areas (such as Bangladesh, the coastal belt of China and most islands in the Pacific and Indian Oceans) will be under water. Rising temperatures will also have serious impacts on agriculture and ecosystems. Energy consumption is projected to double in Asia and the Pacific and to increase by 50-70 per cent in Latin America between 1990 and 2010. Therefore, the process of transferring energy-saving technologies between Western and developing countries should be strengthened. In particular, we should use economic incentives to enable industrialists to develop process technologies that improve the efficiency of industrial resource utilization. Schematic diagram of the greenhouse effect
Thirdly, the diversity of organisms decreases. Due to urbanization, agricultural development, deforestation and environmental pollution, natural areas are becoming smaller and smaller, which leads 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 medicines, and will also lead to the disappearance of many genes that can help crops to overcome the harsh climate, and even cause epidemics. IV. Reduction of forest area. In recent decades, countries in the tropics have also experienced a significant reduction in forest area. Between 1980 and 1990, 150 million hectares of forest disappeared. At the current rate of forest area reduction, after 40 years, some South-East Asian countries will no longer see a single tree. Freshwater resources are threatened. According to experts' estimation, starting from the beginning of the next century, a quarter of the world will suffer from chronic water shortage. Remember, we cannot make water, we can only try to protect it. Sixth, chemical pollution . Millions of compounds from industry are present in the air, soil, water, plants, animals and humans. Even the ice caps, the last large natural ecosystems on earth, are polluted. Organic compounds, heavy metals, and toxic products are concentrated throughout the food chain and ultimately threaten the health of plants and animals, cause cancer, and reduce soil fertility. Chaotic urbanization. By the end of the century, there will be 21 large cities in the world, where living conditions will further deteriorate: crowding, polluted water, poor sanitation, insecurity - the uncontrolled expansion of these large cities is also detrimental to natural areas. Unrestricted urbanization should therefore be seen as a new evil of civilization. VIII. Overexploitation of the oceans and pollution of coastal zones. Polar ozone hole
The fishery resources of the oceans are diminishing at a frightening rate due to overfishing. As a result, many poor people who depend on ingesting seafood protein for their livelihoods are threatened with starvation. Substances such as heavy metals and organophosphorus compounds concentrated in fish have the potential to cause serious health problems for fish eaters. Coastal areas are under tremendous population pressure. Sixty percent of the world's population is crammed into areas less than 100 kilometers from the sea. This state of overcrowding throws these often fragile places out of balance. IX. Air pollution. The air in most large cities contains many pollutants from heating, transportation and factory production. These pollutants threaten the health of tens of millions of citizens and have resulted in the loss of many lives. The main toxic gases are carbon monoxide, sulphur dioxide, nitrogen dioxide and respirable particles. X. Polar Ozone Hole. Although people have signed the Montreal Protocol, but every spring, in the Earth's two polar regions of the sky is still formed again ozone layer hole, the Arctic ozone layer loss of 20% to 30%, Antarctic ozone layer loss of more than 51%.
Edit Definition Connotation
Environmental protection is a general term for all human activities that utilize the theories and methods of environmental science to coordinate the relationship between human beings and the environment, to solve various problems, and to protect and improve the environment. Including, take administrative, legal, economic, scientific and technological measures, the rational use of natural resources, to prevent environmental pollution and damage, in order to maintain and develop ecological balance, expand the reproduction of useful natural resources, to ensure the development of human society. Environmental protection (environmental protection) involves a wide range of comprehensive, it involves many fields of natural and social sciences, as well as its unique research object. Environmental protection includes at least three levels of meaning:
Protection of the natural environment
Preventing the deterioration of the natural environment. This includes: the protection of green mountains, green water, blue sky and sea. Here it involves no private mining (mines) and indiscriminate logging (trees), no indiscriminate discharge (sewage) and release (polluted gas), no overgrazing, no over-exploitation of land, no over-exploitation of natural resources, no disruption of the ecological balance of nature, and so on. This level is of a macro nature and relies mainly on governments at all levels to exercise their functions and regulation before it can be resolved.
Protection of the environment for human habitation and living
To make it more suitable for human work and labor. This involves all aspects of people's clothing, food, housing, transportation, and play, all of which must meet the requirements of science, hygiene, health, and green. This level belongs to the micro, both by the conscious action of the citizens, but also rely on the government's policies and regulations as a guarantee, relying on the community's organization and education to guide the industry, agriculture, soldiers, academics and businessmen from all walks of life to grasp the **** management, in order to solve.
Protection of the Earth's living creatures
Preservation of species, conservation of plant vegetation, the return of animals, biodiversity, genetic modification, protection of endangered organisms
Rational and prudent use of endangered organisms, special and particular protection of endangered organisms, restoration of extinct species, expansion of habitats, harmonious ****ing between humans and living creatures, and no bullying of other species and so on. The relationship between these three dimensions is: you have me, I have you, each has its own focus but is unified; they are not contradictory, let alone opposing. As citizens, if we protect our living environment, we indirectly or directly protect the natural environment; if we destroy our living environment, we directly or indirectly destroy the natural environment. As a government, we should not only focus on macro-protection, but also start with micro-protection, mobilize the masses and educate them, so as to make environmental protection a conscious action of the 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 conservation" to "environmental protection"; China put forward the policy of "comprehensive utilization" of industrial wastes in 1956, and the "three wastes" policy in the late 1960s. China put forward the policy of "comprehensive utilization" of industrial wastes in 1956 and the concept of "three wastes" treatment and recycling in the late 1960s, and then switched to the more scientific concept of "environmental protection" in the 1970s. According to the provisions of the Law of the People's Republic of China on Environmental Protection, the content of environmental protection includes the protection of the natural environment and the prevention and control of pollution and other public hazards. In other words, we should use the theories and methods of modern environmental science to better utilize the resources and at the same time to y understand and grasp the root causes and hazards of pollution and damage to the environment, to protect the environment in a planned manner, to restore the ecology, to prevent the deterioration of the quality of the environment, to control the environmental pollution, and to promote the coordinated development of human beings and the environment. China attaches importance to environmental protection is still relatively late, and now there is still a gap in the degree of attention at all levels of government, can be called environmental protection government is not common. So it is still too early to talk about environmental protection citizens.

Edit Measures
1. Air conditioning winter 18 summer 26 degrees, the national electricity savings of hundreds of millions of degrees The air conditioning temperature in winter is set to 18 degrees or below. If you feel a little cold, you can add more clothes, such a simple initiative can save electricity, thereby reducing coal-fired power generation emissions of carbon dioxide and other greenhouse gases, slowing down the warming of the climate. Set your air conditioner to 26 degrees or above in summer. The air-conditioning load in large cities accounts for about 40%-50% of the maximum power supply load in summer. Raising the temperature of air-conditioners from 22-24 degrees to 26-28 degrees can reduce the power load by 10%-15% and reduce power consumption by more than 400-600 million kWh. People sweat in the summer is good for health, can enhance metabolism, regulate endocrine function and promote autoimmunity. 2. light bulbs into energy-saving lamps to save nearly eighty percent of the home's ordinary light bulbs into energy-saving light bulbs, and to buy after the "National Energy Conservation Product Certification" of the product, you can be printed through the word "section" logo to judge. In the same luminous flux conditions, energy-saving lamps than incandescent lamps can save 80% of the electricity, for the purchase of energy-saving lamps in the cost of (8 ~ 10) months in the electricity bill savings can be recovered. 3., garbage classification does not litter recycling good regeneration in the garbage, about 50% is biological organic matter, about 30% -40% with recycling value. 2000, China produced six recyclable waste volume were: 41.5 to 43 million tons of scrap iron and steel, waste non-ferrous metals 1 to 1.2 million tons, waste rubber 850,000 to 920,000 tons, Waste plastic 2.3 to 2.5 million tons, waste glass 10.4 million tons, waste paper 10 to 15 million tons. At present, China's annual value of unutilized waste reaches 25 billion yuan, and about 3 million tons of scrap iron and 6 million tons of waste paper are not recycled. The recycling rate of waste plastics is less than 3%, and the recycling rate of rubber is 31%. Only thrown away every year more than 6 billion waste dry batteries containing more than 70,000 tons of zinc, 100,000 tons of manganese dioxide. 4. do not use electrical appliances cut off power saving 10% can see Home and office appliances, such as TV, computer, etc., please turn off the power when not in use. In standby mode, the average hourly power consumption of the television 8.07 joules, air conditioning 3.47 joules, 7.69 joules of monitors, PC host 35.07 joules, range hoods 6.06 joules. Turning off the power of this small move can help you save money on electricity, but also to protect the environment. 5, the high energy-consuming enterprises to encourage the installation of energy-saving facilities Over the past decade, due to energy constraints, with the further development of energy conservation. A variety of new, energy-saving advanced furnace is becoming more and more perfect, and the use of new refractory fibers and other high-quality insulation materials make the kiln heat loss decreased significantly. The use of advanced combustion devices to strengthen the combustion, reducing the amount of incomplete combustion, air-fuel ratio also tends to be reasonable. However, the technology of reducing heat loss of exhaust smoke and recovering flue gas waste heat is still not progressing fast. In order to further improve the thermal efficiency of the kiln, to achieve the purpose of energy saving, recovery of flue gas waste heat is also an important energy-saving way. Flue gas waste heat recovery is usually used in two ways: one is to preheat the workpiece; the other is to preheat the air for combustion. Flue gas preheating workpiece needs to occupy a large volume for heat exchange, often subject to the limitations of the operating site (intermittent use of the kiln can not use this method). Preheated air combustion is a better method, generally configured in the heating furnace, but also to strengthen the combustion, accelerate the heating speed of the furnace, improve the thermal performance of the furnace. This not only meets the requirements of the process, and finally can also obtain significant comprehensive energy-saving effect. In addition, the domestic from the fifties in industrial furnaces and kilns on the use of preheating air preheater, the main form of tubular, cylindrical radiation and cast iron block and other forms of heat exchanger, but the exchange efficiency is low. In the eighties, the domestic has developed a jet type, jet radiation type, compound table type heat exchanger, mainly to solve the low temperature waste heat recovery. In 100 degrees below the flue gas waste heat recovery has achieved remarkable results, improve the heat transfer efficiency. However, at high temperatures is still due to the heat exchanger material limitations, low service life, maintenance workload or solid cost is expensive and affect the popularization of the use. At the beginning of the 21st century, Gongyi City, Henan Province, China finally developed the Ronghua ceramic heat exchanger. Its production process and kiln production process is basically the same, thermal conductivity and oxidation resistance is the main application of the material performance. It is the principle of the ceramic heat exchanger placed in the flue outlet closer to the higher temperatures, do not need to be mixed with cold air and high temperature protection, when the kiln temperature of 1250-1450 ℃, the flue outlet temperature should be 1000-1300 ℃, ceramic heat exchanger recovery of waste heat up to 450-750 ℃, will be recycled to the hot air into the kiln and the gas to form a mixture of gas for combustion, can save energy! 35% -55%, which directly reduces production costs and increase economic efficiency. Ceramic heat exchanger in the use of metal heat exchanger under the limitations of the development of a good, because it is a better solution to the corrosion resistance, high temperature and other issues, and has become the recovery of high-temperature waste heat recovery of the best heat exchanger. After years of production practice, shows that ceramic heat exchanger effect is very good. Its main advantages are: good thermal conductivity, high-temperature strength, oxidation resistance, good thermal shock resistance. Long life, small maintenance, reliable and stable performance, easy to operate. It is the best device to recover high temperature flue gas waste heat. At present, the ceramic heat exchanger can be used in metallurgy, non-ferrous, refractory, chemical, building materials and other industries, the main thermal kiln, is for the world's energy saving and emission reduction cause has made a great contribution.

Environmental costs Environmental costs, also known as environmental degradation costs, refers to the cost of the decline in the quality of environmental service functions due to environmental pollution caused by economic activities. Environmental degradation cost is divided into environmental protection expenditure and environmental degradation cost, environmental protection expenditure refers to the value actually paid for the protection of the environment, and environmental degradation cost refers to the value of the loss of environmental pollution and the value that should be paid for the protection of the environment. The natural environment mainly provides living space and ecological efficacy, and has the characteristics of long-term and multiple use, which is also similar to the characteristics of fixed asset use. In this way, the cost of environmental degradation caused by pollution from economic activities, that is, the cost of environmental degradation, also has the nature of "fixed asset depreciation".
Edit Chemical curing agent for sludge
Especially the curing of river sludge or municipal sewage sludge With the large number of construction of municipal sewage treatment plants, the volume of sewage treatment and the production of sludge are increasing. Sludge contains a large number of microorganisms . Pathogens. Heavy metals and organic pollutants, its water content is generally more than 80%, improper treatment will cause secondary pollution. Currently, sludge disposal methods mainly include agriculture . Incineration and landfill, there is a large amount of sludge without any treatment, randomly discarded. Due to the high water content of sludge, poor soil mechanical properties and high pollutant content, the current treatment methods have environmental pollution. The treatment cost is too high, but also easy to cause landfill engineering geological disasters. Whether sludge can be landfilled depends on the geotechnical mechanical properties of sludge or sludge and other additives to form a mixture of sludge, sludge landfill requirements cross plate shear strength ≥ 25kpa, unconfined compressive strength of ≥ 50kpa. sludge after conventional dewatering, the moisture content of 80% or more, the word plate shear strength <10kpa, can not meet the minimum requirements of landfill. For this reason, it is necessary to improve the mechanical properties of sludge and reduce the water content. The traditional way is to add cement and lime and other curing agents, but also use mineralized waste as an additive mixture, these ways need to add a large amount of material, add the amount of <30%, increasing the amount of waste, if then water, will be transformed into sludge. The use of adding chemicals to solidify sludge, the amount of additives can be controlled within 10%, the general maintenance time in 1 ~ 3 days, you can reach the landfill requirements of strength and moisture content. It must be used rationally. Low cost and good effect
