摘　　要：利用复合膜生物反应器工艺研究填埋场垃圾渗滤脱氨运行环境,在常温环境下运行结果表明:HSMBR反应器大量截留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NH4+-N具有高效的去除效率;工艺运行参数在硝化池HRT为50～60h环境下,NH4+-N的MLSS负荷为0.06～0.09g/(g·d),DO质量浓度为3.0～3.5mg/L,硝化池pH值在7.50～7.80,脱除NH4+-N的效果较好,去除率在95%～98%。An experimental study was carried to optimize condition of deamination with hybrid-submerged membrane bioreaetor （HSMBR） in the treatment of urban landfill leachate. The course result with normal temperature showed that highly removal rate of NH4＋-N was obtained in treatment urban landfill leaehate with HSMBR, and nitrobaeteria with longer generation time formed domination bacteria in shorter time. When HRT was 50 - 60 h, steady load of MLSS of NH4＋-N was 0.06 ~ 0.09 g/（g .d）, DO was 3.0 - 3.5 mg/L and pH value was 7.50 - 7.80 in the nitration pool, the hybrid-submerged membrane bioreactor had a better removal rate of NH4＋-N, and the removal rate of NH4＋-N was 95% ~ 98%.
