摘　　要：利用固相静态试验考察前期实验驯化出的真菌Trichoderma viride Peers.er．Fr对苯、甲苯、二甲苯的好氧生物降解性能。结果表明，在本研究的气相浓度范围内（苯47．25—1677．47g/m^3，甲苯64、70—1258．50g／m^3、二甲苯20．59—1707．85g／m^3），3种气体的降解速率随其初始浓度的增大而增加，降解规律苯、甲苯符合Monod方程，二甲苯符合一级反应。The degradation performance of benzene,toluene and xylene by fungus Trichoderma viride Pers.ex Fr were studied.The experimental results showed that the biodegradation rate of benzene,toluene and xylene increased with increasing of their initial gas concentrations; when concentrations of them were 47.25～ 1 677.47 g/m3 ,64.70～ 1 258.50 g/m3 and 20.59～ 1 707.85 g/m3 respectively, the biodegradation rate of toluene and benzene accorded with the Monod equation,while that of xylene accorded with first-order reaction.
