Buried AO process and high-load dephosphorization wetland system

Abstract

The invention discloses a buried AO process and a high-load dephosphorization wetland system, and belongs to the technical field of AO processes, the buried AO process and the high-load dephosphorization wetland system comprise a grid pool, a filter grid is arranged in the grid pool, the front end of the grid pool is connected with a sewage discharge pipe, the other end of the grid pool is connected with a discharge pipe through a water pump, one end of an anaerobic pool is connected with an aerobic pool, one end of the sedimentation tank is connected with the aerobic tank, and the other side of the sedimentation tank is connected with the high-load dephosphorization wetland and the sludge storage tank. The buried AO process and the high-load phosphorus removal wetland system have the advantages of better COD and ammonia nitrogen removal in the AO process, overcome the defect of poorer phosphorus removal effect of the traditional phosphorus removal wetland, and overcome the defects of easiness in blockage caused by rotten plant root systems in the phosphorus removal wetland and sinking into the wetland in the traditional AO process, the sewage treatment effect, especially the phosphorus removal effect, of a small treatment station is effectively improved, and the standard reaching rate of sewage treatment and the stability of equipment operation are greatly improved.

Description

technical field [0001] The invention relates to the technical field of AO technology, in particular to an underground AO technology and a high-load dephosphorization wetland system. Background technique [0002] During the discharge process of wastewater, it changes with the change of production conditions, and there are uneven water quality and unstable water quantity. Especially when there is an accident in production or there is a lot of rain, the water quality and quantity of wastewater will change more. This change will cause abnormality in the wastewater treatment process, reduce the treatment effect, and cannot fully utilize the design load of the treatment equipment. Contents of the invention [0003] The purpose of the present invention is to provide a method that has the advantages of removing COD and ammonia nitrogen in the AO process, overcomes the disadvantages of poor phosphorus removal in traditional artificial wetlands, and overcomes the traditional AO proc...
