Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a rapid coagulation sedimentation tank. Background Art

[0002] Rapid coagulation sedimentation tank is a sewage treatment equipment, which combines the two processes of rapid coagulation and sedimentation. It is used to efficiently remove suspended matter, colloidal substances and some organic matter in sewage. Coagulant is added when sewage enters the coagulation area, and is fully mixed through mixing components, so that the coagulant can react with sewage quickly and evenly, promoting the aggregation of suspended matter and colloidal particles. The coagulated water flows into the sedimentation area. In this area, the suspended matter is quickly settled to the bottom through the design of reasonable structure and flow mode, and the clean water flows out from the top.

[0003] When the rapid coagulation sedimentation tanks currently on the market are in use, certain floating objects and flocculants will adhere to the inner wall of the rapid coagulation sedimentation tank when treating sewage. The existing rapid coagulation sedimentation tanks need to be manually cleaned by staff when cleaning the inner wall, and the cleaning process is relatively cumbersome. Therefore, improvements should be proposed to the current rapid coagulation sedimentation tanks. Utility Model Content
