| 摘 要： | 采用固相萃取前处理和气相色谱／质谱联用的方法，分析厌氧．膜生物反应器处理垃圾渗滤液中多环芳烃的去除效果．结果表明，对多环芳烃的总去除效率超过80％；大部分三环、四环和五环的芳烃可在处理过程中被厌氧降解．多环芳烃的主要降解反应发生在厌氧滤池工艺段，然而SCOD(溶解性化学耗氧量)，BOD和TOC的主要去除工艺段则是膜生物反应器．

| Abstract: | Removal of PAHs in a municipal landfill leachate by the anaerobic membrane bioreactor technique was explored based on chemical analysis using solid phase extraction for sample preparation and GC/MS for determination.The results showed that this combined bioreactor could be used efficiently for removal of PAHs from landfill leachate.The total removal efficiency of PAHs was more than 80%.In the process,most of three ring,four ring and five ring aromatic hydrocarbons could be anaerobically degraded.The degradation of PAHs mainly occurred in anaerobic filter tank,while SCOD,BOD and TOC were mainly removed in the membrane bioreactor.The removal of SCOD,BOD and TOC could not demonstrate the reduce of PAHs during the treatment process. |
