摘要: 采用气相色谱-电子捕获(GC-ECD)法对X市城市污水及其常规处理工艺出水中的多氯联苯(PCBs)和有机氯农药(OCPs)进行分析研究.在X市城市污水中共检出5种PCBs(PCB28、PCB52、PCB101、PCB153、PCB180)和5种OCPs(α?HCH、β?HCH、γ?HCH、δ?HCH、艾氏剂),浓度在0.314 3~3.499 3ng/L之间,同国内外报道的结果相比,X市城市污水中PCBs和OCPs总量处于较低水平.该市城市污水处理厂二级处理工艺对PCBs和OCPs具有较好的去除效果,平均去除率分别为65.14%和87.39%,其中生化处理单元的贡献最大,去除率大于50%.
英文摘要: The gas chromatography-electron capture detection(GC-ECD) method is adopted to analyze the contents of polychlorinated biphenyls(PCBs) and organochlorine pesticides(OCPs) from domestic wastewater at different stages of a wastewater treatment plant in the city.As a result,five kinds of PCBs(PCB28,PCB52,PCB101,PCB153,PCB180) and five kinds of OCPs(α-HCH,β-HCH,γ-HCH,δ-HCH,Aldrin) are detected from the raw wastewater,the concentration rangs from 0.314 3 to 3.499 3 ng/L.Compared with the reported PCBs and OCPs c...
