In recent years, in order to improve this situation, many cities have begun to explore the construction of new rain and sewage diversion system. These systems realize the preliminary separation of rainwater and sewage at the source through physical isolation, thereby reducing the pressure of subsequent sewage treatment plant and improving the overall water quality management efficiency.

[0028] The utility model has the following beneficial effects:

[0029] 1. In this utility model, the rainwater is diffused on the filter plate by the action of the inclined plate. The filter plate adopts a multi-stage design to intercept larger garbage and debris and small impurities. The rainwater with lower density flows upward along the slope of the inclined plate and is discharged through the drain pipe located at the top, while the heavier sewage sinks to the bottom and flows out through the sewage pipe, which improves the separation accuracy of rainwater and sewage and reduces the risk of pollutants spreading to natural water bodies.

[0030] 2. In this utility model, the rotating handle and the elliptical block rotate synchronously.
