According to the characteristics of domestic sewage with high phosphorus and other complex content in a phosphatizing factory in Hubei Province,and the strict local discharge emission limits,the AAO+MBR+Chemical Precipitation process is adopted in this project,the scale of main body treatment is 120 m3/d,and the scale of MBR membrane process treatment is 80 m3/d.The operation of the project shows that the process has a good treatment effect,and the effluent quality is better than the Grade A standard of"Pollutants Discharge Standard of Urban Sewage Treatment Plant"(GB 18918-2002).The total phosphorus and fluoride can meet the requirements of environmental protection standards,which can effectively reduce the pollutant load discharged into the Han River.The operation cost of the project is 1.339 9 yuan/m3,which has high popularization and application value for the treatment of the same type of domestic sewage in phosphating plants along the river.
