摘　　要：采用生物滴滤塔去除甲苯废气中的甲苯,考察了气体流量和液体流量对净化效率、出口与进口温差及塔内温度分布的影响。结果表明:逆流操作的净化效率高于顺流,气(液)体流量对出、进口气(液)体温差有较大影响。The trickling biofilter was used to remove the toluene from waste-gas. The influence of gas flow and liquid flow on the purification efficiency, temperature difference between outlet and inlet, and temperature profile in filter was investigated. The result shows that the purification efficiency is higher under counter current operation than that under co-current operation. Gas flow rate/liquid flow rate has greater influence on the gas/liquid temperature difference between outlet and inlet.
