View From The Factory Sewage Water Pollution Prevention Measures To Improve The Prevention And Control Law

China's water pollution situation is grim, the seven main river basins of the country have all been heavily polluted. The pollution of the river basin is mainly urban and point source pollution caused by industrial and mining enterprises, because of the irrational distribution of industry in all major river valleys are to varying degrees along the layout of the heavy chemical industry, and even the distribution of the phenomenon of environmentally sensitive areas, Thus, a sewage outfall into the river will be polluted a large, pollution in major rivers, with the formation of the shore; in tributaries of the river, the pollution of a factory so that the entire river will be contaminated into a "sewage ditch." Shows the importance of prevention and treatment of sewage plant, sewage plant control has been the focus of China's water pollution control work, how truly effective prevention and treatment of sewage plant behavior is the purpose of this thesis.From an ecological point of view, the main stream and the river basin is composed of water and its many tributaries, the surrounding environmental elements to form a complete system. Maintain the ecological system of the relative stability of the structure in order to ensure watershed stability and integrity to perform their ecological functions. Study at home and abroad have reached a consensus view from the integrated and coordinated river basin water pollution control is the overall trend of environmental protection, it is also bound to prevent and control industrial pollution into the watershed scale.The first chapter first analyzes the characteristics of the basin and the basin, presented the status of water pollution by sewage flow within the factory survey of pollution from the Yellow River, Huaihe River, Yangtze River and the Xiangjiang River in several key distribution and industrial pollution start the relationship, and the sewage plant caused water pollution in recent years, the serious fact that the sewage plant obtained the status of water pollution in the basin is very important, is the water environment pollution, an important factor in the conclusion.The second chapter summarizes the water pollution prevention and control of the achievements of the legal system building, implementation results and the current system of China in the prevention and control of water pollution prevention approach to the sewage plant, the more authoritative by the National Environmental Statistics Yearbook and the Environment in China's statistical data general concluded that the initial deterioration of water pollution has been checked, but the situation is not optimistic about the water quality has not improved fundamentally, water pollution is still serious.The third chapter analyzes the current legal aspects of water pollution in the underlying causes of the failure of that dualism of the Environmental Protection Act guidelines focused on economic development led to serious pollution of the water plant the root causes of the environment; of the irrational industrial distribution industry, extensive economic growth way, the low utilization rate of water consumed in large industrial situation and the reality of weak legal system, punishment is a reality leading cause of severe industrial pollution. And that the environmental carrying capacity water basin water environment protection is the core issue in the study of pollutant carrying capacity of river basin, according to environmental capacity to control the emissions of pollutants, is the protection of water environment to implement effective measures are to achieve sustainable economic development and environmental protection an important part of river basin water. Therefore, total control is the most effective water pollution control system.ChapterⅣfirst proposed under the total control system design of the sewage plant control system. Described in four aspects: first, the convection within the industrial structure adjustment and rational distribution of the settlement basin pollutant carrying capacity of the sewage basin over the basic method; second, improve the system of pollution permits, pollution permits should be made total control as a precondition to licensing and should be adjusted with the seasons; Third, the construction project environmental impact assessment system improvement, which is pollution prevention and control production capacity of more than an important watershed pollutant carrying capacity of the procedural arrangements; Fourth, improve the shut down system, pollutant carrying capacity of watershed pollution more than required shutting down approach to emissions, must be noted that shutting down the process of transfer and after the unreasonable rebound problem. Second, the article pointed out that the number of water pollution control system currently exists to some extent the deficiencies and defects.
