摘　　要：本文通过试验采用A/O膜生物反应器对垃圾渗滤液进行了处理,结果表明：当厌氧水力停留时为15 h、好氧水力停留时间为30 h、回流比为300%~400%时,CODCr、BOD5、氨氮及TN的平均去除率分别为85.2%、91.6%、88%和43.9%;人工投加碳源后,TN的平均去除率提高到77.7%;在反应器好氧区中形成了大量高端营养级水平微生物种群,食物链长且相互交叉,呈明显的网状结构,可保证系统稳定的污水处理效果及较强的抗冲击负荷能力。An A/O membrane bioreactor was applied to the treatment of landfill leachate.The test research suggested that at the conditions of the anaerobic hydraulic retention time of 15 h,the aerobic hydraulic retention time of 30 h and the return ration of 300%-400%,the average removal rates of CODCr,BOD5,NH3-N and TN were 85.2%,91.6%,88% and 43.9%,respectively.After the addition of carbon source,the average removal rate of TN increased to 77.7%.In the aerobic zone,there were large numbers of higher trophic level microbial populations,and the food chains were long and crossed,and exhibited a web structure.
