摘要
Abstract
In view of the problem that the current effluent of an industrial wastewater treatment plant(WWTP)in southern Jiangsu is difficult to meet the discharge standards of Discharge Standard of Main Water Pollutants for Municipal Wastewater Treatment Plant&Key Industries of Taihu Area(DB 32/1072-2018),the design idea of MBR+catalytic ozonation is proposed.The original MSBR process is transformed into AAO-MBR process,and the original flocculation sedimentation tank is transformed into catalytic ozonation tank.The influence of factors such as catalyst pollution and cleaning measures in the catalytic ozonation unit on the CODCr removal rate are analyzed emphatically.Results shows that,as a technical route for industrial wastewater upgrading and reconstruction,the MBR+catalytic ozonation occupies less land,has a stable operation effect,and the effluent quality can reach the standard stably.However,the catalytic ozonation is greatly affected by catalyst pollution and other factors,pretreatment and cleaning measures need to be strengthened.The project additional investment is 1 596 yuan/m3,and the additional operation cost is 0.73 yuan/m3,which has good economic benefits.关键词
