中文摘要：
将活性污泥培养及驯化后接种于生物滴滤塔中，挂膜启动后处理模拟氯苯废气（简称氯苯废气），考察了生物滴滤塔在挂膜启动阶段及稳定运行阶段的性能。实验结果表明：接种41d后生物滴滤塔成功挂膜，此时氯苯去除率稳定在90％以上；生物滴滤塔稳定运行阶段，随着进气中氯苯质量浓度由303．82mg／m3逐渐增至1489．05mg／m3，氯苯去除率从85．1％降至70．1％。处理氯苯废气适宜的工艺条件为：空塔停留时间超过45s，喷淋液流量31．8mL／min，氯苯负荷23．97～128．01g／（m3·h）。生物滴滤塔对喷淋液的酸性环境有较好的适应性，喷淋液pH的变化对氯苯去除率无显著影响。
英文摘要：
The cultured and acclimatized activated sludge was inoculated into the biotrickling filter（BTF） to treat the simulated waste gas containing chlorobenzene. The BTF properties during start-up stage and steady running stage were studied. The expertimental results show that： The biofilm formation is accomplished after 41 d with more than 90% of chlorobenzene removal rate; In the steady running stage, when the inlet chlorobenzene mas concentration is increased from 303.82 mg/m3 to 1 489.05 mg/m3, the chlorobenzene removal rate is decreased from 85.1% to 70.1%. The suitable process conditions for chlorobenzene waste gas treatment are as follows： empty bed residence time over 45 s, spray liquid flow 31.8 mL/min and chlorobenzene load 23.97-128.01 g/（m3 ·h）. The BTF can well fit the cidic environment caused by spray liquid and the spray liquid pH has no significant effect on chlorobenzene removal rate.
