摘　　要：采用厌氧—复合式膜生物反应器(A/HMBR)组合工艺处理模拟生活垃圾中转站废水,考察了水力停留时间和回流比对COD、NH3-N、TN去除效果的影响。结果表明,在水力停留时间为42h、回流比为3时,系统对COD、NH3-N、TN的去除率最高,分别为95%、89%、78%。复合式膜生物反应器中膜污染的主要原因为溶解性有机物对膜孔的堵塞。The anaerobic/hybrid membrane bioreactor （A/HMBR） process was used to treat domestic waste transfer station wastewater, and the influences of HRT and reflux ratio on the removal efficiencies of COD, NH3 - N and TN were investigated. The results indicate that the when HRT and reflux ratio are 42 hours and 3 respectively, the removal rates of COD, NH3 - N and TN are 95%, 89% and 78% respectively. It is found that the main reason of membrane fouling of hybrid membrane bioreactor is blockage of membrane pores by dissolved organic matters.
