The mixed gas of toluene and air was used as treated gas, self-made fluidized bed and ultraviolet lamp and TiO2/silica gel prepared in laboratory used as photo reactor and light source and photo-catalyst respectively to degrade toluene in the treated gas. The effects of operating parameters including initial concentration, operating gas velocity, ultraviolet light intensity and bed layer height on degradation rate of toluene have been probed into in this research. The results showed that degradation rate of toluene was independent of initial concentration (20～55mg/m3) but decreased with higher initial concentration; the degradation rate of toluene increased with gas velocity (below 3.98cm·s-1) but decreased in case of higher gas velocity(above 3.98cm•s-1). The results also showed that the degradation rate of toluene increased with higher light intensity or bed layer height.
