Description

Technical Field

[0001] The utility model relates to the technical field of water outlet weir cleaning, in particular to a cleaning device for a water outlet weir of a secondary sedimentation tank. Background Art

[0002] The sedimentation tank after biological treatment is usually called the secondary sedimentation tank or the final sedimentation tank (final sedimentation tank). The function of the secondary sedimentation tank is to separate mud and water, clarify the mixed liquid, concentrate the sludge and return the separated sludge to the biological treatment section. The effect of the secondary sedimentation tank directly affects the water quality of the effluent and the concentration of the returned sludge.

[0003] An outlet weir is set in the secondary sedimentation tank, and the upper side of the outlet weir is set in a triangular plate shape. The sewage that has been precipitated in the secondary sedimentation tank overflows over the outlet weir and is output, and flows out from the adjacent triangular plate of the outlet weir. As the use progresses, there will be a lot of moss or other stains on the outlet weir, affecting the normal overflow water.

[0004] Therefore, the water outlet weir needs to be cleaned regularly. The current cleaning method is to wipe it manually with a handheld brush or rag. In this way, only the triangle plate of one water outlet weir can be cleaned at a time, which is inefficient. Utility Model Content
