Centralized pollution control refers to the centralized treatment facilities and management measures established and adopted to protect the environment within a specific scope, which is an important means to strengthen environmental management.
The purpose of centralized pollution control is to improve the environmental quality of control units such as river basins and regions. According to pollution prevention and control plans and according to the nature, type and geographical location of waste water, waste gas and solid waste, centralized pollution control is the main way to achieve as much environmental, economic and social benefits as possible with the smallest possible input.
The forms of pollution centralized control include water pollution centralized control, exhaust pollution centralized control, harmful solid waste centralized control and noise centralized control.
Why centralized pollution control?
The centralized control of pollution is summarized from the practice of environmental management in China. Past often too much emphasis on pollution control of a single pollution source management, the pursuit of the rate and success rate, is actually a "band-aid" and "becoming", zero cracking, although spent a lot of money, a lot of sweat, make a lot of pollution control facilities, but that is not large area overall environmental quality improvement, environmental pollution has not been effective control. Years of practice have proved that pollution control in China must aim at improving environmental quality and follow the principle of increasing economic benefits. That is to say, the fundamental goal of pollution control is not to seek the treatment rate and compliance rate of individual pollution sources, but to seek the improvement of environmental quality as a whole, and at the same time stress economic efficiency, so as to obtain as much benefit as possible with as little investment as possible. Therefore, the centralized control of pollutants appeared and developed in the practice of environmental management.
What are the benefits of centralized pollution control?
First of all, centralized pollution control conforms to China's national conditions. If a large number of enterprises that discharge pollutants are required to build separate pollutant treatment facilities, it is economically unreasonable and complicated to manage. Therefore, through rational planning, focusing on pollution control by region or river basin, pooling limited funds and adopting relatively advanced technology and standards, it is possible to achieve greater comprehensive benefits, which is in line with the reality of Our country. Secondly, centralized pollution control can be welcomed by most enterprises. Because, most of the small and medium enterprises due to the capital is not much, low level of technology, small sites and other reasons, are willing to follow the principle of "who pollution who pay", their hazardous waste entrusted with specialized technology treatment plants to deal with, and pay reasonable fees. Third, the centralized control of pollution also conforms to the international development trend. At present, hazardous waste treatment and treatment facilities in industrialized countries are becoming larger and more centralized, and many enterprises are commissioning regional waste treatment centers to centrally treat the waste generated in their production.
What is the basic practice of centralized pollution control?
First, centralized pollution control must be guided by planning. Centralized pollution control is closely related to urban construction, such as improving drainage pipe network, establishing urban sewage treatment plants, and developing urban greening. At the same time, urban pollution centralized control is a complex system engineering. Therefore, centralized pollution control must be planned, implemented and developed simultaneously with urban construction.
Second, to control urban pollution centrally, we should divide different functional areas, give prominence to key areas and control them separately. Because the nature, types and environmental functions of pollutants in different regions are different, the main environmental problems are also different. Therefore, functional zoning is needed so that different approaches to different environmental problems can be adopted.
Third, centralized pollution control must be led by local governments, with government leaders in charge, coordinating various departments and dividing their responsibilities. Because centralized pollution control involves not only enterprises, but also all government departments and all sectors of society, it is difficult for any one government department to accomplish it alone. Therefore, the government needs to come forward, organize and coordinate the relations among all sectors, and take charge of the implementation separately.
Fourth, centralized pollution control should be combined with decentralized treatment. Because to a few harm serious, discharge heavy metal and the pollution source of harmful material that biodegrades hard, to a few large enterprises or individual pollution source far from town, must undertake alone, disperse management.
Fifth, to implement centralized pollution control, to dredge a variety of funding channels. Centralized pollution control can save money on the whole compared with decentralized control, but the one-time investment is large. Therefore, it is necessary to raise funds from various sources, including polluters and beneficiaries, loan funds for environmental protection, environmental protection funds for enterprise construction projects, bank loans, local financial subsidies, and relying on national energy policies, urban reform policies, enterprise reform policies, etc.
Of course, there are also some problems to be noticed in implementing centralized pollution control. For example, the environmental protection department found in the law enforcement inspection of the industrial park that some facilities and equipment for centralized pollution control in the industrial park had serious leakage and theft of discharge, which did not play a role in pollution control, but became a place to collect pollution. Therefore, only by strengthening law enforcement and supervision and eliminating the phenomenon of pollution centralized control of equipment discharge can centralized control play a greater role
