摘　　要：以磺胺甲基嘧啶(SM1)、磺胺甲恶唑(SMZ)、四环素(TC)、罗红霉素(ROX)、氧氟沙星(OFL)、咖啡因(CF)、对乙酰氨基酚(AP)等7种典型药物为研究对象,选择MSBR、BAF两个实际污水处理系统和一个多级A/O-MBBR中试处理系统,通过高效液相色谱质谱技术(HPLC-MS)检测7种药物在不同工艺单元的浓度水平,考察不同系统对不同药物的去除效果。结果表明,MSBR系统对7种药物的去除效果为AP>CF>OFL>TC>ROX>SM1>SMZ,BAF系统为CF>ROX>AP>OFL>TC>SMZ>SM1,多级A/O-MBBR中试系统为AP>CF>OFL>ROX>TC>SM1>SMZ。3个处理系统对AP、CF、OFL和TC的去除率没有显著差异;BAF系统对SM1的去除率仅为6.8%,显著低于其他两个系统;多级A/O-MBBR系统对SMZ的去除率仅为10.75%,显著低于其他两个系统;BAF系统对ROX的去除率高达92.9%,显著高于其他两个系统。Two practical wastewater treatment systems(MSBR and BAF)and a multi-stage A/O-MBBR pilot treatment system were applied to treat seven typical pharmaceuticals including SM1,SMZ,TC,ROX,OFL,CF and AP.Their concentrations in different units of the treatment system were determined by HPLC-MS,and the removal effects of different pharmaceuticals by different treatment systems were investigated.For MSBR system,the removal efficiency of seven pharmaceuticals in descending order was as follows:AP,CF,OFL,TC,ROX,SM1 and SMZ,for BAF system was CF,ROX,AP,OFL,TC,SMZ and SM1,and for multi-stage A/O-MBBR pilot system was AP,CF,OFL,ROX,TC,SM1 and SMZ.There was no significant difference in the removal efficiency of AP,CF,OFL and TC among the three systems.The SM1 removal efficiency of the BAF system was only 6.8%,which was significantly lower than that of the other two systems.The SMZ removal efficiency of the multi-stage A/O-MBBR system was only 10.75%,which was significantly lower than that of the other two systems.The ROX removal efficiency of the BAF system was 92.9%,which was significantly higher than that of the other two systems.
