摘　　要：以装填活性炭纤维布填料的生物滴滤塔为试验装置,以模拟氯苯废气为降解目标物,分别采用快速排泥法和气液相联合法对滴滤塔进行挂膜启动。结果表明:气液相联合法23 d实现挂膜启动,比快速排泥法挂膜启动时间缩短20 d左右,去除率变化更加稳定,进气中氯苯浓度4 000 mg/m3时两者去除率均达到50%。The start-up and biofilm culturing process of biotrickling filters treating waste gas containing chlorobenzene were studied.Sludge fast discharge method and gas-liquid phase joint inoculation method were used during start-up.The results showed that the start-up time of the latter is shorter,i.e.about 20 d,the removal efficiency kept above 50% when inlet chlorobenzene concentration about 4 000 mg/m3 at the end of start-up.
