Description

Technical Field

[0001] The invention belongs to the technical field of sedimentation tanks, and in particular relates to a high-efficiency sedimentation tank which is easy to clean. Background Art

[0002] In the field of sewage treatment, high-efficiency sedimentation tanks are widely used in industrial wastewater treatment and urban sewage treatment because they can effectively collect and precipitate impurities and particulate matter in sewage. In order to improve the sedimentation efficiency, many sedimentation tank designs adopt inclined tube or inclined plate structures to accelerate the sedimentation of particulate matter by increasing the length of the water flow path and changing the direction of the water flow. However, this design also brings new problems: sludge is easily accumulated on the surface of the inclined tube or inclined plate. These sludges will undergo anaerobic reactions during the long-term accumulation process, produce gas and cause the sludge to float, thereby affecting the sedimentation effect and effluent water quality. In addition, the cleaning method of traditional sedimentation tanks mostly relies on manual flushing with high-pressure water guns, which is not only inefficient, but also requires the equipment in the sedimentation tank to be stopped for a long time. The flushing angle of the high-pressure water gun is not easy to adjust, and there are dead corners, which increases labor intensity and cost. Summary of the invention
