摘　　要：试验采用含甲苯和乙酸乙酯的基质溶液对接种污泥进行反复选择培养驯化,获得具有高效降解能力的优势菌种。利用正交实验确定了菌种固定化的最优条件。通过调整生物滴滤塔喷淋液的pH,确定处理有机废气的最优pH为7.0。试验分析了滴滤塔不同有机物进口浓度在填料层高度的浓度分布情况,结果表明填料层下部的有机物降解速率大于上部的降解速率,说明在较低浓度下,有机物的降解主要受传质过程的控制。The dominant bacterial strains could be obtained through domestication and culturing of the active sludge. Optimal preparation condition of the strain immobilization is carried out by the cross - test experiments. The effects of pH on the removal efficiency of organic waste gases were studied by experiment, and the best conditions were pH - 7.0. Test results show that the degradation efficiency of lower biological packing is apparently superior to upper biological packing. At lower concentration, the process of biotrickling filter was controlled by mass transfer.
