Water spraying type float sludge cleaning device for secondary sedimentation tank

The utility model discloses a water spraying type float sludge cleaning device for a secondary sedimentation tank. Relating to the field of water body monitoring, suspended sludge in a water body in asecondary sedimentation tank is non-uniformly distributed; precipitation is not liable to occur, the water quality is influenced. The device comprises a water tank, a pipeline, a pump, a nozzle and afirst water pipe, the pipeline is positioned above the secondary sedimentation tank; one end of the pipeline penetrates the top of the water tank; nozzle is arranged on pipeline, the nozzle is obliquely arranged; the water flow sprayed from the nozzle is sputtered onto the float sludge on the surface of the secondary sedimentation tank; the sludge cleaning device has the advantages that water inthe water tank is pumped into the pipeline through the water pump, the water passes through the pipeline and is jetted out of the nozzle, sludge in the secondary sedimentation tank is gathered throughwater flow discharged from
