In order to speed up the construction of Tianjin Binhai Hi-tech Industrial Development Area and improve the regional water ecological environment,it is decided to build a 10,000,m3/d Wastewater Treatment Plant.Through detailed research and comparison,the process of pretreatment-A2O biochemical treatment-advanced treatment-ecological treatment process was selected.When the construction was completed,inoculation methods were adopted to produce activated sludge.Since the operation,the effect has been proved stable and reliable,and effluent factors of treated water reached:COD 31.3—40.2,mg/L,BOD 8.1—8.4,mg/L,SS 8.2—8.6,mg/L,NH3—N 3.8—4.2,mg/L,TN 9.6—10.8,mg/L and TP 0.39—0.4,mg/L.The effluent quality meets the first class A criteria of Discharge standard of pollutants for municipal waste-water treatment plant(GB,18918—2002).
