[0002] Generally, in the back-end treatment unit structures of sewage treatment plants, such as the secondary sedimentation tank, as the effluent quality improves, algae will gradually appear under sufficient sunlight, which can easily affect the effluent quality. The secondary sedimentation tank is a key process installed after the biochemical reaction tank. Algae easily gather near the secondary sedimentation tank outlet weir and outlet trough, which will affect the system's effluent water volume and water quality. The secondary sedimentation tank outlet weir and outlet trough need to be cleaned regularly. At present, the cleaning method for the secondary sedimentation tank outlet weir and outlet trough is generally to use a manpower-driven flat brush for brushing, which is inefficient and has poor cleaning effect.
