摘　　要：垃圾渗滤液是垃圾卫生填埋处理过程中的副产品,是一种水质复杂、污染物浓度高的有机废水,且随着填埋年限的增加水质变化显著,其中的污染物成分会对环境和人体健康产生巨大威胁,相比于生活污水处理难度极大。该文在总结了垃圾渗滤液的水质特征基础上,对渗滤液的处理方法进行了分类,将近年来用于渗滤液处理的主要物化方法(包括氨吹脱、混凝沉淀、吸附、化学氧化、膜分离和紫外-超声等)和生物方法(包括厌氧法、好氧法和厌氧氨氧化等)进行了综述,重点介绍了生物法处理渗滤液的优缺点和国内外研究进展,以期为渗滤液的无害化处理提供研究方向和参考方法。Landfill leachate is a by-product of landfill sanitary treatment,it is a kind of organic wastewater with complex water quality and high contaminant concentration,and the water quality changes significantly with the increase of landfill life.The contaminant composition in it will pose a great threat to the environment and human health,which is extremely difficult to be treated compared with domestic sewage. Based on the summary of the water quality characteristics of landfill leachate,in the present paper the treatment methods of leachate were classified,and the main physical and chemical methods for leachate treatment(including ammonia stripping,coagulation sedimentation,adsorption,chemical oxidation,membrane separation and UV-ultrasound,etc.) and the biological method(including anaerobic,aerobic and anaerobic ammonium oxidation,etc.)used in recent years were reviewed also.The advantages and disadvantages of biological treatment of leachate and the research progress at home and abroad were introduced,in order to provide the research direction and reference methods for the harmless treatment of landfill leachate.
