摘　　要：采用三级固液分离-USR-UASB-化学除氨-SBR-AO-氧化塘处理养猪污水,处理规模为500 m^3/d,原水COD为10 000~15 000 mg/L、BOD_5为5 000~8 000 mg/L、SS为4 000~10 000 mg/L、NH_3-N为800~1 000 mg/L、TP为25~80 mg/L,处理后出水COD为300~380mg/L、BOD_5为120~150 mg/L、SS为150~200 mg/L、NH_3-N为60~80 mg/L、TP为5~8 mg/L,出水水质优于《畜禽养殖业污染物排放标准》(GB 18596—2001)。The integrated processes of three-level solid-liquid separation unit, USR, UASB, chemical ammonia removal unit, SBR, AO and oxidation pond were applied to treat piggery wastewater. The treatment capacity of the integrated processes was 500 m^3/d. When the influent respective COD, BOD5, SS, NH3 - N and TP was 10 000 - 15 000 mg/L, 5 000 - 8 000 mg/L, 4 000 - 10 000 mg/L, 800 -1 000 mg/L and 25 -80 rag/L, the effluent value was decreased to 300 -380 mg/L, 120 - 150 mg/L, 150 -200 mg/L, 60 -80 mg/L and 5 -8 mg/L, accordingly. The effluent quality was superior to that of the Discharge Standard of Poultry Cultivation Industry Pollutant （GB 18596 -2001 ）.
