摘　　要：采用上流式厌氧污泥床（UASB）／膜生物活性炭反应器（MBACT）联合处理垃圾渗滤液，考察了对COD、BOD5、NH^-_4-N、TN和重金属的去除效果，同时，采用气相色影质谱联机（GC／MS）定性分析了出水中的有机物种类。结果表明，UASB／MBACT组合工艺对COD、BOD”氨氮、TN的去除率分别可达到67.7％、99.1％、62.3％、16.5％，对Cu、Mn、Pb等重金属的去除率在30％～78％之间；组合工艺对饱和烷烃类或带有羧基和羟基官能团的饱和脂肪族类有机污染物的去除效果较差。The combination of upflow anaerobic sludge blanket （UASB） and biological activated carbon membrane reactor was used to treat landfill leachate produced from the disposal of municipal solid waste. The treatment efficiencies of COD, BOD5, NH^-_4 - N, TN and heavy metals were investigated. The organic pollutants in the effluent were analyzed by using GC/MS technique. The results showed that the removal rates of COD, BOD5, NH^＋_4 -N and TN were 67.7% , 99.1% , 62.3% and 16.5% respec- tively. The removal rates of Cu, Mn, Pb and other heavy metals were from 30% to 78%. The treatment efficiencies of saturated alkane or aliphatic organic compounds with carboxyl and hydroxyl groups were poor.
