采用膜生物反应器(MBR)处理垃圾焚烧厂渗滤液,并采用GC/MS技术考察了MBR处理渗滤液过程中有机污染物的降解特性.结果表明,生化段对C4～C8的有机物有较好的降解能力,而无机膜对C16～C19的有机物的去除效果较好;生化段对渗滤液中酸类有机物的降解效果明显,而无机膜对酮、醇、酸类有机物的去除效果明显;当进水COD为57 000 mg/L、NH3-N为665mg/L时,MBR出水的COD和NH3-N分别可降至457、8.54 mg/L.
採用膜生物反應器(MBR)處理垃圾焚燒廠滲濾液,併採用GC/MS技術攷察瞭MBR處理滲濾液過程中有機汙染物的降解特性.結果錶明,生化段對C4～C8的有機物有較好的降解能力,而無機膜對C16～C19的有機物的去除效果較好;生化段對滲濾液中痠類有機物的降解效果明顯,而無機膜對酮、醇、痠類有機物的去除效果明顯;噹進水COD為57 000 mg/L、NH3-N為665mg/L時,MBR齣水的COD和NH3-N分彆可降至457、8.54 mg/L.

The membrane bioreactor (MBR) was applied to treat the leachate from municipal solid waste incineration plant, and the degradation mechanisms of the organic pollutants in the leachate were investigated by GC/MS technology. The results show that the biological process degrades well the pollu-tants having 4 to 8 carbon atoms, while the inorganic membrane process removes well pollutants having 16 to 19 carbon atoms. The organic acids are degraded well in the biological process, and the organic ke-tones, alcohols and acids are removed well in the inorganic membrane process. When the influent COD and NH3-N are 57 000 mg/L and 665 mg/L, the effluent COD and NH3-N can decrease to 457 mg/L and 8.54 mg/L respectively.
