摘要
介绍了UASB-SBR-混凝沉淀工艺处理养猪场废水工程实例。结果表明：对于CODcr达到2000～3500mg／L、NH2～N达到350～1100mg／L的养猪场废水，利用该工艺CODcr的平均去除率达到92．39／5，NH3-N的去除率达到90．0％。其余各项指标均可以满足《畜禽养殖业污染物排放标准》的要求。
The essay introduced the project example of using the craft of UASB-SBR-coagulation and sedimentation craft to treat Livestock and poultry breeding wastewater. The result showed that ： Live- stock and poultry breeding wastewater in which CODcr rearched 2000-3500 mg·L^-1 and NH3-N achieved 350-1100 mg ·L^-1. The average elimination rates of CODcr and NH3-N were respectively 92.3% and 90. 0 % after using this craft. The remaining indicators could reached the criteria of Discharge Standard of Pol- lutants for livestock and poultry breeding（GB18596 -- 2001）.
