Sewage treatment measures

Eight measures to prevent and control sewage: 1, strict control of the total amount of pollutant discharges, continue to cut industrial pollution, iron and steel, electric power, chemical industry, coal and other key polluting industries to promote the wastewater recycling closed-circuit zero-discharge system, and effectively strengthen the audit and supervision of polluting emission units. 2, accelerate the construction of water-saving industry and water-saving society. Further study industrial water conservation management methods, standardize the scope of water conservation in enterprises, and strictly implement water consumption quotas and water conservation standards for key water pollution discharging industries.3. Vigorously promote urban wastewater treatment and resource utilization. Fundamentally avoid the continued deterioration of the urban water environment, in addition to improving the urban drainage system, improve the technical level of urban sewage treatment. Water-scarce cities in the planning of sewage treatment facilities at the same time to arrange for the construction of reuse facilities to carry out the depth of sewage treatment. 4, the development of ecological agriculture and organic agriculture, integrated prevention and control of surface pollution. In the future, we will mainly promote organic fertilizers and formulate plans to reduce the amount of pesticides and chemical fertilizers, so as to effectively solve the problem of surface pollution in agriculture.5 Measures will be taken to effectively protect the marine ecological environment.6 Scientific and reasonable deployment of water resources to ensure ecological water use. The development and utilization of water resources should be based on the premise of protecting the function of the water environment, taking into account the needs of the upper and lower basins of water resources, and licenses should be issued according to the total amount of water resources that can be developed.7 Priority should be given to the protection of the water quality of drinking water sources. Regulations should be formulated for the protection of urban and rural drinking water sources throughout the country, and all kinds of development activities should be strictly limited within the protected areas of water sources.8 Strict control of persistent organic pollutants should be carried out. China's large-scale use of pesticides makes the proportion of persistent organic pollutants in water bodies is high, which should be strictly controlled. Town drainage and sewage treatment regulations, Article 20: urban drainage facilities within the coverage of the drainage units and individuals, should be in accordance with the relevant provisions of the State will be discharged into the urban drainage facilities. In rainwater and sewage diversion areas, sewage shall not be discharged into the rainwater network. Article 21: Enterprises and institutions engaged in industrial, construction, catering, medical and other activities, and individual industrial and commercial households (hereinafter referred to as drainage households) discharging sewage into urban drainage facilities shall apply to the competent urban drainage department for a license to discharge sewage into the drainage network. The competent urban drainage department shall, in accordance with the relevant national standards, focusing on matters affecting the safe operation of urban drainage and sewage treatment facilities for review. Drainage households shall discharge sewage in accordance with the requirements of the sewage discharge into the drainage network license.
