摘　　要：以苯为目标污染物,玻璃弹簧负载型TiO2膜为催化剂,在紫外线照射下,探讨了自制反应器内湿度、苯气体的流速和初始浓度对降解效果的影响。结果表明:气体流速为5 L/min时苯的降解效率为74.6%,湿度为30%时苯的降解效率为81.6%,初始浓度为0.158 mg/L时苯的降解效率为94%,在这三种情况下苯的降解效果最好。In this paper benzene was chosen as the target pollutants, using home - made device, and the effect of initial concentration, air humidity and gas flow on the degradation of benzene was analyzed. Main results showed that the degradation rate of benzene was 74. 6% when the gas flow rate is 5 L/min, the degradation rate of benzene is 30% when the conditions of the humidity was 30%, the degradation rate of benzene is 94% when the initial concentration of benzene is 0. 158 mg/L. The degradation effect of benzene was the best under these three conditions.
