A laboratory scale biofilter inoculated with Pseudomonas putida (MTCC 102) was used for degradation of toluene present in air. Wood charcoal was used as the filter media and a layer of glass beads (6mm) was used for improved air distribution. The biofilter was operated continuously for a period of 5months at four different flow rates - 0.06, 0.12, 0.18, and 0.24m(3)h(-1), with inlet concentration of toluene ranging from 0.04 to 4.5gm(-3). Air having toluene vapor was fed to the biofilter at various loadings ranging from 30.6 to 1104.5gm(-3)h(-1). The removal efficiency was obtained in the range of 70-99.5%. The maximum elimination capacity of 872.5gm(-3)h(-1) was observed at the inlet load of 1104.5gm(-3)h(-1). Wood charcoal was found to an effective biofilter media for toluene biodegradation.
采用接种了假单胞菌（MTCC 102）的实验室规模生物滤池来降解空气中的甲苯。木屑被用作过滤介质，一层 6 毫米的玻璃珠用于改善空气分布。生物滤池在四个不同的流速-0.06、0.12、0.18 和 0.24m³h⁻¹下连续运行了 5 个月，甲苯入口浓度范围为 0.04 至 4.5gm⁻³。甲苯蒸气空气以 30.6 至 1104.5gm⁻³h⁻¹的各种负荷送入生物滤池。去除效率在 70-99.5%范围内。在入口负荷为 1104.5gm⁻³h⁻¹时，观察到最大消除容量为 872.5gm⁻³h⁻¹。木屑被发现是一种有效的甲苯生物降解生物滤池介质。
