摘　　要：利用膜生物反应器研究垃圾填埋场垃圾渗滤运行环境,在常温环境下,运行结果表明：膜能够截留大量并使世代时间长的硝化菌在最短的时间富集成为优势菌种,对垃圾渗滤液中氨氮具有高效的去除效率;氨氮负荷0.082~0.109gN/gMLSS.d,CODC r负荷0.136~0.192g CODC r/gMLSS.d,DO 2.0~3.5mg/L,脱除氨氮的效果较好,去除率在95%~98%,CODC r去除率60%~70%。An experiment was conducted to study optimization of operation conditions for membrane bioreactor at ambient temperature to treat landfill leachate.The result showed that the membrane intercepted and enriched a lot of nitrobacteria with long generation time to make them as dominate bacteria in short time.So it was able to remove NH3-N from leachate with high rate.The process was operated with parameters as NH3-N load rate of 0.082~0.109 g/g MLSS·d;CODCr load rate of 0.136~0.192 g/g MLSS·d and DO of 2.0~3.5mg/L.The removal rates of NH3-N and CODCr were 95%~98% and 60%~70%,respectively,being good effects of denitrification.
