摘　　要：采用GC-MS技术分析生物-物化组合工艺[SBR+混凝+Fenton+曝气生物滤池(BAF)]处理垃圾渗滤液中各处理单元对有机污染物的去除特性。结果表明,垃圾渗滤液原水中检测出70种有机污染物。组合工艺对有机污染物的总去除率达到99%,其中57种有机物被完全去除,10种有机物去除率可达90%以上,3种有机物去除率达50%以上。另外,SBR基本去除芳香烃类、酯类等小分子量的有机物,而Fenton对大分子量的有机物去除效果较好。The characteristics of removal of typical organic pollutants by the biological-chemical combined treatment system,including sequence batch reactor（SBR）,coagulation,Fenton and biological aerated filter（BAF）processes,were investigated by using GC-MS technique.Seventy kinds of organic pollutants were detected and discovered in landfill leachate.As a result,the total removal efficiency of all organic pollutants was 99% by the combined process,and 57 kinds of organic pollutants were completely removed,10 kinds of organic pollutants were removed by more than 90% while the removal efficiencies of others reached over 50%.Moreover,SBR could degrade low molecular weight fractions significantly,such as aromatic hydrocarbons and esters.and Fenton process could degrade the high molecualr weight fractions preferentially.
