摘　　要：以二氧化钛为光催化氧化剂,对废水中的分散大红RR染料进行了处理.实验考察了催化剂投加量、光强、溶液深度、溶液的 pH值及溶液的初始浓度对水处理效果的影响.归纳出负载型二氧化钛光催化降解分散大红 RR染料的最佳条件,探讨了不同因素对水处理效果影响的原因.结果表明以二氧化钛为光催化氧化剂直接处理分散大红RR染料,脱色率可达93%.The treatment of wastewater containing scarlet dyestuff by using the immobilized photocatalyst of titanium dioxide was studied.The treatment effect of reaction quantity,light intensity,solution depth,pH value of wastewater and its initial density were investigated,then the best factors were deduced.Moreover,the causes of different factors’ influence on the treatment were probed. The results showed that the treatment effect of scarlet dyestuff could reach 93%.
