摘　　要：对比研究了UASB-MBAC工艺、普通MBR工艺及投加专性耐盐菌强化MBR工艺处理垃圾渗滤液,特别是对高含盐垃圾渗滤液的效果。结果表明:采用普通MBR处理高含盐垃圾渗滤液时,对有机物去除能力有限,运行时间越长,处理效率越低;投加耐盐菌可有效改善MBR对高含盐渗滤液中有机物的去除效果。试验发现不论是普通MBR还是投加耐盐菌强化的MBR处理高含盐渗滤液时,对氨氮都具有较高的去除率,几乎达到100%。In this research we compare the processes of UASB-MBAC, normal MBR and MBR applied with halotolerant bacteria in treatment of landfill leachate. Especially we research the effect of these reactors treating high salinity landfill leachate. The research results show. the normal MBR have limited capability to remove organic substances. The longer operation of the facility, the removal efficiency is decreased more. The organic substances removal of MBR from high salinity landfill leachate could be improved by additionally applied halotolerant bacteria. While we also no- tice that they all have high removing rate of ammonia nitrogen, nearly 100%.
