摘　　要：用气相色谱质谱联用法对"MIC+MBR"组合工艺处理垃圾渗滤液过程中不同阶段有机质的变化情况进行了初步分析,结果表明:渗滤液中的含氧官能团主要是羟基、酚羟基、醇羟基、甲氧基和羰基等,其含有的有毒致癌物种部分属于难降解物质。微生物在处理工程中首先将简单的低分子量的有机物降解,同时通过使有机质从高分子量的烷烃降解为低分子脂肪烃进而将其完全降解。The change of organism was analyzed by GC-MS during the process of treating leachate with MIC ＋ MBR process, and the result shows that the oxygen functional groups of leachate mainly contain hydroxyl, phenolic hydroxyl, methoxyl, carhonyl and so on, the toxic carcinogenic species of leaehate belong to the refractory matters. In the treatment process, microorganism can degrade the low molecular weight organics first, meanwhile they can he degraded from high molecular weight alkane to the low molecular weight aliphatic hydrocarbon then make them completely degraded.
