摘　　要：以城市垃圾渗滤液为处理对象,就膜生物反应器(MBR)在处理垃圾渗滤液过程中对污染物去除效果进行了研究.结果表明,MBR对垃圾渗滤液中污染物的去除效果较好.在水力停留时间为25-112 h,化学需氧量(COD)和NH4+-N容积负荷分别为0.32-2.22和0.14-0.50 kg.m-3.d-1的条件下,MBR对COD和NH4+-N的去除率分别为81.2%-88.2%和99%以上;在C/N比为5.2,回流比为300%的条件下,系统对总N去除率为75.2%-82.2%,且随C/N变化呈直线关系,其线性回归方程为y=16.129x-0.6866(R2=0.9884).The removal effect of contamination was investigated by treating the urban landfill leachate with a membrane bioreactor. Experimental results showed that membrane bioreator （MBR） had high efficiency in contamination removal. When volume loading rates of chemical oxygen demand （COD） and NH4^＋-N were between 0.32 -2.22 kg·m^-3·d^-1 and 0.14 -0.50 kg·m^-3·d^-1 respectively, the MBR had removal efficiencies of COD and NH4^＋ -N ranging between 81.2% - 88.2% and over 99% respectively at hydraulic retention time （HRT） between 25 h and 112 h. When C/N and cireumfluenee rate of mixed liquor were 5.2 and 300% respectively, the system had removal rates of total nitrogen ranging between 75.2% and 82.2%, and C/N had linear relation with the removal rates of total nitrogen, its regressing equation was y = 16. 129x -0. 6866 （R^2 = 0.9884）.
