摘　　要：以具絮凝、吸附、降解多功能粉煤灰污水处理材料,填充成絮凝沉降降解过滤箱,组合有鼓气、臭氧的连续式5级垃圾场渗滤液集成处理系统。垃圾渗滤液流量、鼓气量、臭氧量分别为40Lh、40L(m3·h)、15mgL的工艺条件下,渗滤液的悬浮物、色度、CODCr、BOD5、氨氮、硫化物等主要污染物指标分别降低93%、90%、96%、92%、86%和92%,达到垃圾场渗滤液二级控制标准。A system of treatment of municipal landfill leachate was combined by five-series trunks filled with multifunction fly-ash such as adsorption,coagulating,decomposition and so on.Under processing conditions of flow rate of 40 L/h for landfill leachate,40 L/(m^3·h) for air and 15 mg/L for ozone,respectively,suspended substances,colority,COD_ Cr,BOD_5,ammonia nitrogen and sulfide in the leachate were cut down by 93%,90%,96%,92%,86% and 92%,respectively.
