The paper outlines treatment of waste gas containing monochlorobenzene (MCB) and benzene in a mixture using biofilter packed with compost and woodchips seeded with Acinetobacter calcoaceticus. The biofilter could treat waste gas containing MCB and benzene effectively with an efficiency of (99+/-5%) and (97+/-6%) at optimal empty bed contact time (EBCT) of 3 min with a loading of 57 g/m(3)/h of MCB and 2g/m(3)/h of benzene. At optimum loading of MCB and benzene, the biofilter showed total bacterial count of 13 x 10(5)CFU/g of compost, while the MCB and benzene degrading bacterial count was 71 x 10(4)CFU/g and 5 x 10(4)CFU/g compost respectively. The experimental removal efficiency of MCB and benzene were in good agreement with the model predicted value.
本文概述了使用填充有熟堆肥和木屑并接种了不动杆菌属（Acinetobacter calcoaceticus）的生物过滤器来处理含有一氯苯（MCB）和苯的混合废气的方法。在最佳空床接触时间（EBCT）为 3 分钟，MCB 负荷为 57 g/m(3)/h，苯负荷为 2 g/m(3)/h 的条件下，该生物过滤器对含有 MCB 和苯的废气的去除效率（99+/-5%）和（97+/-6%）非常高。在 MCB 和苯的最佳负荷下，生物过滤器中的总细菌计数为 13 x 10(5)CFU/g 堆肥，而 MCB 和苯降解菌的计数分别为 71 x 10(4)CFU/g 和 5 x 10(4)CFU/g 堆肥。MCB 和苯的实验去除效率与模型预测值吻合良好。
