摘要： 以生物滴滤法处理模拟甲苯和二甲苯废气，以甲苯和二甲苯为碳源，筛选并分离纯化了能够降解甲苯、二甲苯的4种高效菌株，并对它们的形态特征进行了观察和鉴别；确定了甲苯、二甲苯废气处理流程并进行了生物滴滤塔的初步设计，选用了8种不同的填料，通过对填料的成膜时间以及对甲苯二甲苯的降解效率的考察，最终选定松木块为填料；在温度为25 ℃，湿度高于60%，pH为7的条件下，考察了入口负荷浓度、气体流量、喷淋量对甲苯、二甲苯及两者混合气体的处理效果影响,结果表明，生物滴滤塔能够有效处理低浓度甲苯、二甲苯气体，处理效果受入口负荷浓度、气体流量、喷淋量等条件的影响。

Abstract: Toluene and xylene waste gases were harmful to the environment and human health, the study on toluene and xylene waste gases treatment by using biotrickling filter tower was rare. In this paper, biotrickling filter tower was used to treat simulation toluene and xylene waste gases, toluene and xylene as the carbon source. Then screened, separated and purified four kinds of high efficiency strains of degrading toluene and xylene waste gases, their morphological characters were observed and identified. The treatment process of toluene and xylene waste gases was determined and the preliminary design of the biotrickling filter tower was carried out. Eight kinds of fillers were studied, the pine wood was finally selected as the filler after explored the film forming time of fillers and the degradation efficiency of toluene and xylene. While the temperature was 25 ℃, humidity was higher 60%, pH was 7, the effects of the entrance load concentration, gas flow rate and the spray volume on degradations of toluene, xylene and its mixed gases were explored, the results indicated that biotrickling filter tower could effectively degrade low concentration toluene, xylene. The treatment efficiency was affected by entrance load concentration, gas flow rate and the spray volume.
Key words: biotrickling filter tower; toluene; xylene; screen; treatment efficiency
