摘要： 采用新型开放式旋转圆型光催化反应装置处理染料污水,探讨染料的初始浓度、pH值、处理料液的体积、反应器的转速、光照时间对脱色效率的影响。对5种不同结构的染料进行了研究。结果表明,对所试几种染料品种,pH值为6是最佳值,20min为最佳反应时间,处理料液体积和反应器转速对半导体光催化反应有一定影响;在优化条件下,采用悬浮态TiO2时,染料的脱色率为98%。

Abstract: Wollen-dyeing waster water was treated in a new type of open and revolling photocatalytic reactor.From some important factor which may affect the photocatalytic degradation of the organic dyes such as the initial concentration of the dyes,pH value,the volume of the feed solution,and the rotating rate of the reactor,solar radiation time which influence removal efficiency was studied.The results show that optimal pH value and optimal reaction time for degradation of the dyes are pH value 6 and 20 min respectively.The degradation efficiency is affected by thickness of water in the reactor rate.Over 98% degradation by suspended TiO 2 are observed under optimal conditions.
