The precipitator (pool) is a device for removing suspended matters in water by utilizing the precipitation effect, and the purpose of purifying water quality is achieved. The suspended substances in the water are removed by utilizing the natural sedimentation or coagulating sedimentation of the water. The precipitator is divided into a horizontal sedimentation tank and a vertical sedimentation tank according to the water flow direction. The settling effect is determined by the flow rate of the water in the settling tank and the residence time of the water in the tank. In order to improve the sedimentation effect and reduce the occupied area of equipment, a honeycomb inclined tube counter-current sedimentation tank, an accelerated clarification tank, a pulse clarification tank and the like are mostly adopted at present, and a sedimentation tank of the sedimentation tank is widely used in wastewater treatment. The generation of the inclined plate sedimentation mode is derived from shallow pool theory proposed by har's true (Hazen) in the early twentieth century. The inclined plate sedimentation tank forms a plurality of shallow sedimentation tanks by means of inclined plates, thereby increasing the sedimentation area, and therefore, the treatment capacity of the inclined plate sedimentation tank is remarkably improved. The inclined plate sedimentation tank is generally used in the occasions with larger processing load and smaller working site.

Although the inclined plate precipitator has a plurality of advantages, the conventional inclined plate precipitator has small inclined plate distance, and the precipitation efficiency and the effluent quality of a precipitation tank are obviously reduced after the precipitation tank operates for a period of time or the water quality and the water quantity of water are changed, so that serious sludge accumulation and blockage among the inclined plates are caused, and even the inclined plates collapse.
