Problems solved by technology
[0004] Due to the small volume of the sand chamber, the short residence time of the water body, and the poor flow state, there are many dead zones in the system. Therefore, in most cases, the existing sand chamber is not effective in removing large particles of mud and sand.

The invention discloses a hydraulic vortex rainwater sand settling well, which comprises a well body which is respectively connected with a water inlet pipe and a water outlet pipe; the well body is provided with a sleeve and a diversion cone fixed in the sleeve by a fixing column. body, the sleeve is surrounded by an oxidation contact device, the periphery of the oxidation contact device is provided with an annular groove, and the gap of the annular groove is connected to the water outlet pipe; the water inlet pipe extends into the well body from the side of the well body and connects with the diversion cone . The rainwater sand settling well of the invention can effectively remove silt and organic matter in rainwater and sewage, and clear the silt in the well through a dredging pump, thereby avoiding blockage of downstream pipelines.
Description
technical field [0001] The invention relates to a hydraulic vortex rainwater sand settling well, which belongs to the technical field of water treatment. Background technique [0002] The initial runoff produced by the initial rainfall scouring the walls, roofs and ground contains a large amount of suspended matter such as mud and sand. On the one hand, a large amount of mud and sand enters the rainwater pipe network through the rainwater well and will be deposited in the pipe, thus weakening the flow of the pipe. The capacity of the pipeline will affect the drainage safety of the pipeline, and even block the pipeline and cause overflow; on the other hand, the initial rainwater runoff pollutants entering the river will seriously affect the improvement of the urban water environment quality. [0003] The rainwater grit well is an important subsidiary structure in the rainwater drainage pipe network. It is mainly aimed at the initial runoff in the rainfall runoff, and the susp...
