Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to sewage treatment equipment. Background Art

[0002] Sewage refers to wastewater that contains various pollutants and is discharged after use. It usually contains various waste materials from human life, industrial production and agricultural activities, such as organic matter, chemicals, heavy metals, bacteria, etc. Sewage will have adverse effects on the environment and human health, so it needs to be treated and purified to reduce pollution and harm to the environment. Methods for treating sewage include physical treatment, chemical treatment and biological treatment. Physical treatment includes sedimentation, clarification, filtration, etc., which purifies water quality by removing solid particles, suspended matter and turbidity.

[0003] In the sedimentation tank, when sewage settles, some impurities may adhere to the inner wall of the sedimentation tank. This is because during the sedimentation process, gravity will cause heavier particles to settle to the bottom of the sedimentation tank, while lighter particles may be suspended in the water or close to the water surface. During this process, some smaller particles or suspended matter may interact with the inner wall of the sedimentation tank and adhere to its surface. The interior of the sedimentation tank has a certain area, which makes it more troublesome for staff to clean. Utility Model Content
