Integrated rainwater and sewage diversion well

Integrated rainwater and sewage diversion well

With the development of cities, black and odorous water bodies have become a serious problem in modern society. In response to the national call, Shanghai Hongyang has put rain and sewage diversion on the agenda and developedIntegrated rainwater and sewage diversion wellIn response to the current situation of direct discharge of sewage through combined sewer pipelines and mixed sewage through separate sewer pipelines, renovation will be carried out,Integrated rainwater and sewage diversion wellThe problem of black and odorous water body caused by initial rainwater overflow was solved. Through the online monitoring system of rainwater and sewage, the sewage in sunny days was directly discharged, the initial rainwater flow was limited, the rainwater was directly discharged during the rainstorm period, and the anti back flow after the rain was prevented. The problem of urban black and odorous water body treatment and the transformation of old small areas of mixed rainwater and sewage flow was solved.

Product Features:
During sunny days, as the water quality in the interception well is all sewage, all sewage gates are opened and rainwater gates are closed. If the elevation of the sewage pipe network is lower than that of the inlet, the sewage can be directly discharged into the city's sewage pipeline, achieving the functions of self discharge and direct discharge; If the water level in the sewage pipe network is higher than the inlet, a water pump needs to be installed in the well to discharge through forced discharge. The water pump will operate according to the values set in advance in the control system.

During the initial rainfall period, the amount of rainfall is relatively small and the pollution level in the well is high. At this time, the gate of the sewage outlet is still opened and the gate of the rainwater outlet is closed. If the elevation of the sewage outlet is higher than that of the rainwater outlet, the submersible pump will automatically start and stop according to the set liquid level parameters, and the initial rainwater will be transported to the municipal sewage pipe network. As the rainfall continues, the water level in the interception well continues to rise, reducing the net weight of sewage pollution. The sewage outlet gate is gradually closed for current interception, while the rainwater outlet gate is opened to ensure smooth drainage of rainwater in the middle and later stages.
During the rainstorm period, the water level in the well rises rapidly, and the pollution degree decreases significantly, reaching the discharge standard. At this time, the gate of the gutter inlet is opened and the gate of the sewage outlet is closed, and the rainwater is directly discharged into the river to avoid ponding.
The integrated interception well is suitable for the treatment of black and odorous water bodies, interception and interception of sewage, rainwater and sewage diversion projects, and the construction of sponge cities. Through its intelligent setting and operation, it automatically diverts rainwater and sewage, and is applied in various industries.
