Li Guowen 1,Hu Hongying 1,2 ,Hao Jiming 1, Ma Guangda 3(1.Dept. of Envir. Sci. & Eng., Tsinghua University, Beijing 100084 China; 2.State Key Lab of Environment Simulation and Pollution Control,Tsinghua University,Beijing 100084; 3.Dept. of Envir.  
The designed test conditions were following: vacancy velocity was from 0 7cm/s to 3 5cm/s,retention time was from 30s to 80s.Column activated carbon was selected as the filler of the reactor and toluene was taken as representative of VOCs.The biodegradation of toluene using biofilter reactor and the influence of concentration,flow and humidity on the toluene removal were investigated and the removal model was set up.The experimental results showed that the biofilter reactor had higher toluene removing ability.The observation of biotic community demonstrated that the microbes consisted of fungi,bacillus and spore bacillus.Of them spore bacillus was dominant.
