摘　　要：以某高含盐垃圾渗滤液为研究对象,通过向膜生物反应器(MBR)中投加粉末活性炭(PAC),研究PAC-MBR组合工艺处理垃圾渗滤液时膜污染状况.结果表明,相对MBR工艺,PAC-MBR组合工艺可有效减缓膜污染,延长膜使用时间,降低工艺成本,并使出水水质得到一定提升,对研究其它类似的高有机物浓度和高盐度污水有一定的参考价值.Taking landfill leachate containing high salinity as the research object,by adding powdered activated carbon（PAC）to the membrane bioreactor（MBR）,the membrane fouling of processing waste leachate by the MBR-PAC combination technology was investigated.The result shows that PAC-MBR can improve the quality of effluent water,and it can mitigate membrane fouling,reduce the frequency of cleaning,extend the lifetime of the membrane.The present study has certain reference value for other similar high concentration of organic matter and high salinity wastewater.
