Description

Technical Field

[0001] This utility model relates to the field of secondary sedimentation tank cleaning technology, specifically a cleaning device for the sidewalls and overflow weir plates of a secondary sedimentation tank. Background Technology

[0002] The sedimentation tank after biological treatment is usually called a secondary sedimentation tank or a final sedimentation tank (final settling tank). The function of the secondary sedimentation tank is to separate sludge from water, clarify the mixed liquor, concentrate the sludge, and return the separated sludge to the biological treatment section.

[0003] Moss often appears in secondary sedimentation tanks, typically growing on the inner and outer walls and overflow weirs. The method used has evolved from plastic brushes to wire brushes. While moss on flat surfaces is relatively easy to remove, cleaning vertical surfaces (overflow weirs and tank sidewalls) is difficult, and manual cleaning is inefficient and poses risks such as slipping.
