Background technique

The topic of water pollution is constantly being brought up, especially the problem of groundwater pollution. Surface water pollution is obvious, but groundwater pollution is shocking. As water pollution continues to intensify, the sewage treatment and regeneration industry has received unprecedented attention. It will cause great harm to the ecological system of the environment. In severe cases, it will destroy the ecology and balance of the water body, stop the circulation of substances, and cause the death of aquatic organisms due to acute or chronic poisoning, which will have a serious impact on the environment.

In order to reduce the pollution to the environment, people carry out centralized treatment of sewage. In order to make the sewage meet the water quality standard for discharge into a certain water body or reuse, the sewage needs to pass through a sedimentation tank during treatment at present to precipitate the impurities in the sewage, which is convenient for the sewage. After further processing, however, the existing sedimentation tank will leave a layer of dirt at the bottom after use, and the sedimentation time of the sedimentation tank is too long, which affects the purification of sewage.
