| 摘 要： | 采用旋转式光催化反应器处理染料废水，探讨染料ｐＨ值，液层厚度，反应器转速，光照时间对脱色效率的影响．结果表明，对所试染料品种，ｐＨ６为最佳值，２０ｍｉｎ为最佳反应时间．液层厚度和反应器旋转速度对半导体光催化氧化反应有一定影响．在优化条件下采用悬浮态ＴｉＯ２时，偶氮染料的脱色率为９８％，采用ＴｉＯ２器壁固定时为７８．５％～９１．５％

| Abstract: | The characteristics of TiO2 catalyzed photodegradation of a azodye in water using rotation reactor was studied.UV lamp was installed in the centre of tubular reactor for uniform radiation.The results showed that optimal pH value and optimal rention time for degradation of the azodye were pH 6 and 20min,respectively.The degradation efficiency was affected by thickness of water in the reactor and rotation rate.Over 98% degradation by suspended TiO2 and 785%915% degradation by fixed TiO2 degradation were observed under optimal conditions. |
