摘　　要：针对某石油化工企业污水处理站产生的大气量混合挥发性有机废气(VOCs)成分复杂、净化率低的难题,在其原有箱式生物滴滤塔(BTF)中投加特异复合微生物菌剂强化混合废气的净化。结果表明:混合废气主要成分为12种C_(4)~C_(8)烷烃类物质和7种苯类污染物;随着环境温度的变化,废气中VOCs总质量浓度为40~150 mg·m^(-3);投加由6种功能微生物组成的混合菌剂之后,BTF对混合废气中TVOCs去除率提高了180%,为对照组的2.8倍。该项目的成功实施可为微生物复合菌剂的工程应用提供参考。In order to address the problem of complex components and insufficient purification for largevolume mixed volatile organic compounds(VOCs)generated by a petrochemical sewage treatment station,,the functional bacterial agents were pertinently added to the original biotricking filter(BTF)to enhance the purification of mixed waste gas.The result indicated that the main components of the mixed exhaust gas were alkane(12 C_(4)~C_(8))and benzene series(7 aromatic compounds),the concentration of total VOCs(TVOCs)in exhaust gas was fluctuated with the environmental temperature at the range of 40~150 mg·m^(-3).After adding the mixed bactericide composed with 6 microorganisms,the removal efficiency of TVOCs was increased by 180%,which was 2.8 times that of the control.The successful implementation of this project can provide a reference for the engineering application of microbial compound bactericides.
