The main function of the sedimentation tower is to remove suspended solids in water and is widely used in the wastewater treatment industry. The sedimentation tower is a sludge-water separation device that separates fine particles of sludge and can be used before and after biochemical treatment of wastewater. The existing sedimentation tower mainly consists of a tower body, an overflow pipe installed on the upper part of the tower body, and a blowdown pipe provided at the lower part of the tower bottom. A sludge inlet is provided on the sedimentation tower, wastewater enters the sedimentation tank through the sludge inlet, and the purpose of sedimentation is achieved through the natural sedimentation of wastewater in the sedimentation tank. This sedimentation method has a long sedimentation time and cannot achieve the purpose of rapid water recirculation in the production process. It does not have a filtering function, and when draining, a part of the sludge and suspended solids will be discharged with the water flow, resulting in poor separation and filtration effect. Moreover, the existing wastewater treatment sedimentation tower cannot remove the colority of high-concentration wastewater, the COD removal rate is low, and the biodegradability of wastewater is low.
