Closed rain and sewage diversion device

Abstract

The invention relates to a closed rain and sewage diversion device. The closed rain and sewage diversion device comprises an equipment cabin, a control unit, a water quality analyzer and a diversion pipeline unit, wherein the control unit is in control connection with the water quality analyzer and the diversion pipeline unit, the diversion pipeline unit is arranged in the equipment cabin, the water quality analyzer is installed in the diversion pipeline unit and is used for monitoring various water quality indexes of mixed water in real time, the control unit is used for sending a control instruction to the diversion pipeline unit in real time on the basis of the water quality indexes obtained by the water quality analyzer, and the diversion pipeline unit is used for controlling the flowing direction and flow of the mixed water. According to the closed rain and sewage diversion device, the control unit, the water quality analyzer and the diversion pipeline unit are integrated in one equipment cabin, so that the equipment volume and cost are reduced, the civil engineering quantity is reduced, and the maintenance and installation difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of rain and sewage diversion equipment, in particular to a closed rain and sewage diversion device. Background technique [0002] Closed rainwater and sewage diversion devices are widely used in underground drainage pipe networks in cities and towns to divert the combined rainwater and sewage in the drainage pipes to solve the pollution problem of the receiving water body caused by the mixed flow of rainwater and sewage. [0003] The rain and sewage diversion method commonly used at present, based on the water volume, intercepts the domestic sewage in the dry period and the initial rainwater with a high degree of pollution and discharges it into the sewage pipe. However, the randomness of pollution sources makes it difficult to grasp the law of pollutant output, and the "one size fits all" interception standard based on water volume is irrational to some extent, which may lead to problems such as overloading...

AI Technical Summary

Problems solved by technology

However, the randomness of pollution sources makes it difficult to grasp the law of pollutant output. The "one size fits all" interception standard based on water volume is unreasonable to some extent, which may lead to problems such as overloading of sewage plants and sewage overflows.

At the same time, the traditional rain and sewage diversion device is limited by the diversion principle, and the amount of civil engineering renovation is large; and manual maintenance needs to be carried out in a narrow and humid environment inside the device, which is difficult to operate and install, and the working conditions are poor
