摘要
建立了基于HLB固相萃取柱和气相色谱 /电子捕获 (GC/ECD)分析垃圾渗滤液中有机氯农药的分析方法 ,对厌氧滤池 膜生物反应器处理垃圾渗滤液不同工艺段水体中有机氯农药的浓度进行了分析 .结果表明 ,应用厌氧滤池 膜生物反应器处理垃圾渗滤液可以有效去除有机氯农药残留 ,主要去除工艺是厌氧 ,其中p,p′ DDT厌氧反应的中间体产物是p,p′ DDD ,大部分继续转化为其它产物 .
Residues of organochlorine pesticides in landfill leachate from different stages of the anaerobic filter membrane bioreactor(MBR)treatment process were preconcentrated by HLB cartridge solid phase extraction and analyzed by gas chromatography/electron capture detector (GC/ECD).Only DDTs and γ HCH were detected,and the concentrations are satisfactory with criteria in Environmental Quality Standards for Surface Water(GB 38338 2002).DDTs and γ HCH could be removed efficiently by anaerobic degradation procedure.The main product of p,p′ DDT anaerobic degradation (dechlorination)was p,p′ DDD,which transform to other chlorinous chemicals in MBR.
