| 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5L／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0．158mg／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。

| Abstract: | 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... |
