中文摘要：

研究了不同条件下产O3低压汞灯对气相中低浓度甲苯的光化学降解，以及活性炭纤维（ACF）对甲苯光解尾气中残余甲苯及光解副产物O3的脱除。结果表明，气流相对湿度（RH）越高、气体流量越大、甲苯的初始浓度越高，甲苯的真空紫外光解速率越高，最高达0．070mg／m^3，所产生的O3浓度也越低气流RH越低，ACF对甲苯和O3的吸附脱除性能越好．负载Mn、Cu氧化物的ACF对O3有更好的分解性能，同时能催化氧化甲苯。在400℃下烙烧的催化剂性能最好，RH8％时对O3的去除率稳定在35％，但当RH增至40％时，对O3的去除率下降为16．9％。

英文摘要：

The photochemical degradation of low concentration toluene in the gas phase by ozone producing low-pressure mercury lamp and the removal action of ACF on residual toluene and by-product ozone in the tail gas toluene photodegradation were studied. The higher the air flow relative humidity （RH）, the greater the air flow amount, the higher the initial ozone concentration, the higher the vacuum ultraviolet photodegradation speed, with highest reaching 0.070mg/m^3, the lower the product ozone concentration. The lower the air flow RH, the better the removal and adsorption properties of toluene and ozone. The ACF loading Mn, Cu oxides had much better degradation property on ozone; meanwhile, could catalyze and oxidize toluene. The catalyst heated at 400℃ showed the best properties, ozone removal rate was stable at 35% when RH was 8%, but it decreased to 16.9% when RH increased to 40%.
