摘　　要：文章对A/O法中的各工序污水以及污泥中PBDEs的含量以及分布状况作了比较系统的分析,采集了水体、污泥共56个样品,经过萃取、净化、浓缩之后利用GC/MS仪器进行分析测定。讨论了PBDEs的污染情况,并对PBDEs与水中常规参数作了初步分析。结果显示,在所采集的样品中均检出了PBDEs,经污水处理后PBDEs主要残留于污泥中,同时污水中的PBDEs主要存在于污水的颗粒相中。水体与污泥中PBDE-209占PBDEs总量的90%左右,其次为PBDE-47与PBDE-99。Grab samples of wastewater and sludge from each unit of process train of an A/O municipal wastewater treatment plant were analyzed,focusing on PBDEs（polybrominated diphenyl ethers）.The study involved extraction,purification and concentration and finally the analysis using GC/MS.The findings indicated that PBDEs are detectable in all the samples, mainly contained in sludge of the secondary sedimentation tank,and PBDE-209 among others accounts for ca.90%of the total PBDEs followed by PBDE-48 and PBDE-99.
