Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sedimentation tank for efficient and environmentally friendly sewage treatment. Background Art

[0002] A sedimentation tank is a structure that uses sedimentation to remove suspended matter from water. It is widely used in wastewater treatment and is one of the most important components of a sewage treatment system. Static sedimentation of sewage and water quality testing are key links in determining the effectiveness of sewage treatment. Some now add flocculants to sewage so that impurities in the sewage form flocs and settle at the bottom of the sedimentation tank, making it easier for staff to clean up. At the same time, most sewage will contain impurities with a density smaller than that of water, which will float on the surface of the sewage.

[0003] However, in some sedimentation tanks nowadays, flocculants settled at the bottom of the tank and floating objects floating on the water surface are mostly cleaned separately and step by step, and both cannot be cleaned at the same time, resulting in low cleaning efficiency. Therefore, we propose a high-efficiency and environmentally friendly sedimentation tank for sewage treatment to solve the above problems. Utility Model Content
