Combined-system pipe network overflow and water body pollution integrated cut-down system

Abstract

The invention discloses a combined-system pipe network overflow and water body pollution integrated cut-down system. The combined-system pipe network overflow and water body pollution integrated cut-down system comprises a CSO regulating storage tank, a biological rapid filter tank, a mud storage tank and a control unit, wherein combined-system overflow water is temporarily stored when the CSO regulating storage tank generates combined-system overflow, and river-way black foul water is temporarily stored when water level is reduced after overflow is ended; when the CSO regulating storage tankrises to be higher than h1 on overflow water level, the control unit controls a river-way water pump at a river-way water inlet to switch off, and controls a first water pump to switch on for pumpingto-be-treated sludge in the CSO regulating storage tank into the biological rapid filter tank, and suspended filler is quickly filtered to hold back suspended solids in sewage; the control unit controls the river-way water pump and the second water pump to start when water level of the CSO regulating storage tank drops to be lower than h2 after overflow is ended, so that river-way sewage enters the CSO regulating storage tank, and the second water pump is used for pumping the to-be-treated sewage in the CSO regulating storage tank into the biological rapid filter tank to generate biochemical reaction under aeration action of a biological membrane and an aeration device, and therefore, dissolution-state pollutants are mainly removed.

Description

technical field [0001] The invention relates to the field of combined system overflow (CSO) and water body pollution treatment, in particular to an integrated reduction system for combined system overflow and water body pollution. Background technique [0002] The water environment is one of the basic elements of the environment, an important place for the survival and development of human society, and the most seriously disturbed and damaged area by human beings. The pollution and destruction of water environment has become one of the major environmental problems in the world today. Urban black and smelly water is a water environment problem that people strongly report, which not only damages the urban living environment, but also seriously affects the image of the city. There are many reasons for the black and odorous water body, and the overflow pollution of the combined drainage system is one of the important reasons. The overflow water of the combined drainage system ...
