摘　　要：采用上流式厌氧污泥床(UASB)与膜生物反应器(MBR)组合工艺对城市垃圾填埋场渗滤液进行处理试验研究。当渗滤液CODCr为1491～2965mg/L,该组合工艺对CODCr、BOD5、NH3-N的平均去除率分别达到73%、98.3%和61.7%。文中还对渗滤液CODCr的降解性能、厌氧—好氧工艺的合理组合等问题进行了讨论分析。Treatment of municipal refuse landfill leachate by the combined system of UASB (Upflow Anaerobic Sludge Blanket) and MBR (Membrane Bioreactor) was tested. During the experiment, the removal rates of COD_(Cr), BOD_5 and ammonia-nitrogen of the combined system achieved 73%, 98.3% and 61.7% respectively when the COD_(Cr) of the influent was 1491～2965?mg/L. Some problems such as the biodegradation of the COD_(Cr) in the leachate and the logical combination of anaerobic-aerobic process were discussed.
