摘　　要：“生化+膜处理”工艺是常用的垃圾渗滤液处理工艺,能够稳定降解渗滤液中的污染物,但存在着膜的使用寿命短、产生的浓缩液较难处理等问题。某老龄化垃圾填埋场现状采用“纳滤+反渗透”渗滤液深度处理工艺,出水COD为124 mg/L,未达到《生活垃圾填埋场污染控制标准》(GB 16889—2008)的排放限值,为此设计采用“高级氧化(Fenton)+曝气生物滤池(BAF)”深度处理工艺,与现状深度处理工艺相比,反应迅速,不产生浓缩液,无二次污染,出水水质达到《生活垃圾填埋场污染控制标准》(GB 16889—2008)的排放限值。The combined process of biochemical technology and membrane treatment is a common landfill leachate treatment process,which can stably degrade the pollutants in the leachate.However,the process has the problems such as short service life of the membrane and difficulty in the treatment of the concentrated solution.The existing advanced treatment process of an aging landfill is nanofiltration-reverse osmosis.The COD in the effluent was 124 mg/L and did not meet the limitation of Standard for Pollution Control on the Landfill Site of Municipal Solid Waste(GB 16889-2008).Therefore,the advanced treatment process of Fenton+aerated biological filter(BAF)was adopted.Compared with the current advanced treatment process,the new process has the advantages of rapid reaction,no production of concentrated solution and no secondary pollution.The effluent quality meets the limitation of Standard for Pollution Control on the Landfill Site of Municipal Solid Waste(GB 16889-2008).
