Embodiment Construction

[0017] The following examples further illustrate the content of the present invention, but should not be construed as limiting the present invention. Without departing from the spirit and essence of the present invention, any modifications or substitutions made to the methods, steps or conditions of the present invention fall within the scope of the present invention.

[0018] Referring to the accompanying drawings, the present invention specifically simulates the effect of multi-technical synergistic pollution control in a town in the Three Gorges Reservoir area, in order to illustrate the content of the present invention and its operating conditions in actual production.

[0019] First of all, in the small town area of ​​the town, the sewage discharged from small towns is mainly treated by decentralized sewage treatment technologies such as membrane bioreactor equipment and septic tanks, and then discharged into the drainage pipes. For drainage pipes, use new rain and sewage...

Abstract

The invention discloses a comprehensive control method for the town water pollution in the three gorges reservoir area, comprising a method for controlling a series of pollutants such as the town industrial and domestic pollution sources discharged out of the small-town area and the city area, the urban non-point source pollution caused by the rainfall runoff generation and the like, so that the comprehensive control method has the characteristics of being feasible in technology, reasonable in economical efficiency, remarkable in combined effect and the like, and the defect that the existing pollutant control method is single in implementation mode, free from technology support, and free from pertinence can be overcome. By respectively setting a water pollution control method for the small-town area of the three gorges reservoir area and the residential district, the dense population business district and the industrial park of the city region, the comprehensive control method for the town water pollution in the three gorges reservoir area is integrated, so that the powerful technology support can be provided for realizing the total water quality target requirement and the pollution abatement work in the three gorges reservoir area of China, and the example can be provided for the town water pollution control of various hydraulic and hydro-power engineering reservoir areas in the western China.

Description

technical field [0001] The invention belongs to the field of water pollution control and treatment, and in particular relates to the technical integration of urban water pollution control. Background technique [0002] The comprehensive control method of urban water pollution is a series of pollutant control technology integration for urban industrial and domestic pollution sources, urban non-point source pollution caused by rainfall runoff, etc. It is technically feasible, economically reasonable, and has significant comprehensive effects. features. [0003] Implementing appropriate pollution control methods for different water areas, different pollution sources and different pollutants is the technical key to effectively realize water pollution control, and it is also the need of China's current national conditions. Combining domestic and foreign research situations, the State Environmental Protection Agency has recommended three pollution control modes in line with China...
