The biological activated carbon filter(BACF)treatment process was adopted in a printing and dyeing park sewage treatment plant in Jiangsu province in response to the problems of long process and high operating costs.The operation results over 3 years show that the COD,TN,NH3-N and TP in the effluent can reach 58 mg/L,8.8 mg/L,0.9 mg/L and 0.3 mg/L,respective-ly,and the effluent quality meets the Discharge standard of main water pollutants for municipal wastewater treatment plant & key industries of Taihu Area(DB 32/1072-2018)Table 3,and the suspended solids(SS)and Chroma also meet the Discharge standards of water pollutants for dyeing and finishing of textile industry(GB 4287-2012)Table 2.Compared to the original process,the technique can significantly shorten the technological process,reduce about 50％of the land occupation,save about 50％of the operating costs,and save an annual operating cost of 16 million yuan.
