An inspection well aeration sand settling device

Abstract

The invention relates to an aeration sand settling device of an inspection well. The aeration sand settling device comprises a sand setting basket, an aeration plate and an air supply assembly, wherein the sand setting basket is arranged at the bottom part of the inspection well, and is used for collecting sand in the water in a water drain pipeline; the aeration plate is arranged in the sand setting basket, and is used for aerating to remove the organic contaminants stuck on the sand, and the air supply assembly is connected with the aeration plate, and is used for providing aeration air for the aeration plate. Compared with the prior art, the aeration sand setting device has the advantages that the air supply assembly is used for providing aeration air for the aeration plate, and the aeration plate is used for aerating to remove the organic contaminants stuck on the sand, so the smelly odor emitted by the inspection well can be avoided, and the environment condition in the inspection well is obviously improved; the contaminants stuck on the sand can be removed by the aeration principle; the cleaning is quick and thorough.

Description

technical field [0001] The invention relates to a sand settling technology in the field of municipal drainage, in particular to an inspection well aeration sand settling device. Background technique [0002] The erosion of rainfall caused a large amount of surface sediment to enter the urban drainage pipes, and at the same time, the water and soil lost due to the damage of the pipes also entered the drainage pipe network. Surface sediments and lost water and soil contain a large amount of high-hardness particulate matter, such as gravel, which will cause silting of drainage pipes and damage the grilles, pumps, centrifuges and other sewage treatment facilities and equipment downstream of the drainage pipes, thereby It affects the normal operation of the sewage lifting pumping station, conveying pumping station and sewage treatment plant. In order to reduce the above-mentioned adverse effects caused by high-hardness granular substances such as gravel, inspection wells with gr...

AI Technical Summary

Problems solved by technology

However, while the traditional sand settling technology removes the gravel, a large amount of organic matter is often attached to the gravel, and it emits a foul smell, which affects the subsequent treatment and disposal of the gravel, especially when a worker enters the inspection well for maintenance. It will smell foul, which is not only uncomfortable, but will also have an adverse effect on its health. Furthermore, the cleaning of grit settling facilities and equipment is difficult, the effect is poor, and maintenance is inconvenient
