A. the²the/O is often designed into integrated sewage treatment equipment, the anaerobic tank, the anoxic tank, the aerobic tank and the sedimentation tank are integrated into one equipment, the integrated treatment equipment has strong impact load resistance, and the capacity of treating industrial wastewater, domestic sewage, urban sewage and the like can be achieved by adjusting the structure of the equipment. The sedimentation tank has multiple structural style, and wherein, vertical flow formula sedimentation tank area is little, and precipitation efficiency is high, has obtained the wide application in fields such as industrial and agricultural waste water treatment, surface water body purification. However, the existing vertical sedimentation tank has certain requirements on hydraulic load, properties of suspended substances and the like, and when the hydraulic load is increased, bottom mud in a mud collecting well is easily stirred up; when the particle size of the suspension is small and the density is small, the precipitation efficiency is greatly affected. The effluent quality of the sedimentation tank is easily influenced by the fluctuation of the influent quality and the water quantityThe water quality is deteriorated due to the noise. For example, the quality of the outlet water of the secondary sedimentation tank of the sewage treatment plant is deteriorated due to the increase of the concentration of the activated sludge in the biological reaction tank, suspended matters near the outlet water collecting tank of the advection sedimentation tank float upwards, and the quality of the outlet water of the inclined tube or inclined plate sedimentation tank is deteriorated along with the increase of the concentration of the suspended matters in the inlet water.

A²A sedimentation inclined plate is commonly used in a sedimentation tank of the last step of the/O integrated sewage treatment equipment, and the sedimentation inclined plate is divided into three types according to the difference of water flow and mud slip directions: the rising direction of the counter-current water flow is opposite to the sliding direction of the sludge, and during working, mud water rushes occur, so that the water yield cannot be further improved; the co-current water flow and the sludge slide down in the same direction, so that the top impact on the downward sliding of the sludge is eliminated, the downward sliding of the sludge is promoted, and the collection of clear water is quite troublesome; the lateral flow water flows horizontally pass through the inclined plate from the lateral direction, and the sludge slides downwards along the inclined plate, so that mutual interference between mud and water is avoided. Meanwhile, the path of the water flow passing through the inclined plate is prolonged, small precipitated flocs are ensured to be separated from water, however, the water flow can generate short circuit at a sludge collecting part, the water quality of discharged water is influenced, and meanwhile, in order to ensure smooth sludge, the inclination angle of the inclined plate of 60 degrees cannot be reduced, the invalid area of the overflowing section is increased, and the separation efficiency is greatly reduced.

Through retrieval, the Chinese authorization notice number is CN101863546B, the application date is 30/06/2010, and the invention name is: a multistage inclined tube or inclined plate sedimentation tank; a multi-stage inclined tube or inclined plate settling tank is disclosed, which mainly comprises a shell, a water inlet and distribution device, a water outlet and collection device, a multi-stage settling wall or a lateral flow inclined plate group, a sludge discharge device and the like. The settling wall is formed by arranging inclined pipes or inclined plates along the vertical surface, and the lateral flow inclined plate group is formed by arranging inclined plates along the horizontal surface. The multi-stage inclined tube or inclined plate sedimentation tank can obviously improve and stabilize the effluent quality of the sedimentation tank, or can allow higher influent suspended matter content under the condition of the same effluent quality. However, in the actual operation process of the inclined plate precipitator, the inclined plate is blocked sometimes due to the problems of unsmooth sludge discharge, untimely sludge discharge, small plate spacing and the like, and the normal operation of the system is influenced. At this moment, the inclined plate needs to be lifted out of the precipitator manually, manual cleaning is carried out, and the cleaning is inconvenient, the working environment is poor and labor is wasted.
