Water flow separate discharge method for urban pipeline network with river, rain and sewage mixed flow

Abstract

The invention relates to a method for discharging water separated, used in mixed tube of city. Wherein, it comprises: arrange diversion tube at the outlet of former discharge tube; the section of diversion tube near the discharge tube has detecting area; the detecting area is arranged with water quality detecting sensor which will transmit the detected water quality to the digit data processor; the processor will process the data to form river water quality factor, to be compared with diversion critical value, to control and select the diversion device to confirm that the water is discharged from the rain discharge tube or sewage tube. The invention can automatically divert water via water quality, to make rain into rain discharge tube and sewage into sewage tube.

Description

technical field [0001] The invention relates to a method for controlling water flow pollution in mixed flow rivers of urban rainwater and sewage, in particular to a method for performing quality-specific discharge of water bodies in urban river rainwater and sewage mixed flow pipe networks. Background technique [0002] At present, the known urban river pollution control mainly includes physical, chemical, biological and other methods and measures: such as cutting off pollution sources from point sources and non-point sources, biodegrading polluted river water, chemical degradation to improve water quality, and sending sewage into sewage Treatment plants, etc., to ensure that the water quality of rivers meets the requirements of different management objectives. [0003] Among them, in order to prevent the water quality of the river from being polluted, the most important and basic measure is to cut off the source of pollution entering the river. [0004] Because people's co...

Problems solved by technology

[0009] The technical problem to be solved by the present invention is that, in order to overcome the existing weaknesses of the decentralized sewage interception and centralized sewage interception systems for non-point source pollution in the existing treatment of river pollution, a system for separating and discharging water flow in urban river rain and sewage mixed-flow pipe networks is provided. The method is to realize the water flow at the outlet of the pipe network that makes the rainwater and sewage mixed flow, and realize three kinds of water outflow options: sewage goes through the sewage pipe, rainwater goes through the river, and although the rainwater and sewage are mixed, the water quality can meet the river water quality management and functional goals, also take the river
