摘　　要：垃圾渗沥液作为一种高浓度的有机废水,主要特点是COD和BOD浓度高、氨氮高、难降解有机物种类多、盐分高,重金属离子多,可生化性差,水质不稳定等。单一的处理工艺很难满足处理如此复杂的垃圾渗沥液,分析了垃圾渗沥液特性和工艺选择中需要注意的问题,并总结了目前的3种主流处理工艺。Landfill leachate is a kind of high concentration organic wastewater. Its main characteristics are of high concentrations of COD, BOD, ammonia, salinity, heavy metal ions, various types of refractory organic matter, low biodegradability, unstable water quality etc. Single processing technology is difficult to deal with such a complex landfill leachate. Several key issues about landfill leachate characteristics and process selection were analyzed, and 3 kinds of mainstream treatment processes were summarized.
