摘　　要：针对养殖场废水COD高、氨氮高、SS高的特点,采用UASB/SBR/化学混凝作为主体处理工艺。UASB反应器采用消化污泥接种,SBR反应器采用好氧活性污泥接种,经过2个月的启动运行,对COD、BOD5、NH3-N、SS、TP的去除率分别达到了91.7%、91.6%、89.4%、98.1%和31.1%,出水各项指标都达到了《畜禽养殖业污染物排放标准》(GB18596—2001)。Based on the characteristics of high COD, high ammonia and high suspended solids in piggery wastewater, a treatment process of UASB/SBR/chemical coagulation was used. The digested sludge was used for seeding in UASB reactor and the aerobic activated sludge was used for seeding in SBR reactor. After start-up for two months, the removal rates of COD, BOD5, NH3 - N, SS and TP reach 91.7%, 91.6%, 89.4%, 98.1% and 31.1% respectively. All the effluent indexes meet the requirement of Discharge Standard of Pollutants for Livestock and Poultry Breeding （ GB 18596 - 2001 ）.
