摘　　要：采用厌氧—缺氧—好氧—混凝沉淀工艺处理垃圾填埋场渗滤液。当进水COD为2 0 0 0mg/L左右时 ,好氧出水COD可降至 90 0mg/L ,混凝沉淀出水COD可降至 80mg/L ;当进水氨氮浓度为 130 0mg/L左右时 ,好氧出水氨氮 <10mg/L。生物处理系统对总氮的去除率较低 ,仅为2 0 %～ 30 % ,因而提高总氮的去除率应是今后研究的方向之一。The results show that A 2/O and coagulation/sedimentation process is feasible for the treatment of landfill leachate. When influent COD is about 2 000 mg/L, COD from aerobic effluent can be reduced to 900 mg/L and COD from coagulation/sedimentation effluent reduced to 80 mg/L; when influent NH 4-N concentration is about 1 300 mg/L, NH 4-N from aerobic effluent can be <10 mg/L. The biological treatment system has less removal rate of TN with 20%～30% only. The future trend of study is to improve the removal rate of TN .
