Description

Technical Field

[0001] The utility model relates to the technical field of water supply engineering, in particular to a sedimentation tank sludge suction device for water supply engineering. Background Art

[0002] Sedimentation tank is an important facility in water supply and drainage engineering. It is mainly used to separate suspended matter and solid particles in sewage and make them settle to the bottom, thereby purifying water quality. The sludge suction device is used in the sedimentation tank to timely extract and remove the sludge settled at the bottom of the tank to prevent anaerobic fermentation of the sludge in the tank, causing the sludge to float and affect the effluent water quality. At the same time, the sludge suction device can also prevent excessive accumulation of sludge at the bottom of the tank and reduce the effective volume of the sedimentation tank, ensuring the normal operation of the sedimentation tank.

[0003] When the existing sedimentation tank sludge suction device for water supply projects is in use, the suspended matter and particulate matter in the sewage gradually settle on the inner wall of the sedimentation tank during the flow process. The sludge accumulated on the inner wall of the sedimentation tank is not only inconvenient to clean, but also reduces the effective volume of the sedimentation tank, affecting its sedimentation effect. For this reason, we propose a sedimentation tank sludge suction device for water supply projects. Utility Model Content
