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.

Abstract

The invention discloses a hydraulic vortex rainwater sand settling well, comprising a well body, wherein the well body is respectively connected with an inlet water pipe and an outlet water pipe; thewell body is provided with a sleeve and a flow guiding vertebral body fixed in the sleeve through a fixing column, the sleeve is surrounded by an oxidation contacting device, the periphery of the oxidation contacting device is provided with an annular groove, and the notch of the annular groove is connected with a water outlet pipe; the water inlet pipe extends into the well body from one side ofthe well body and is connected with the flow guiding vertebral body. The well can effectively remove sediment and organic matter in the rainwater sewage, and the silt in the well is removed by a suction pump, thereby avoiding blockage of a downstream pipeline.

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...
