摘　　要： 对TiO2光催化处理高浓度SF blue制衣染料废水的效果及其影响因素进行了研究。结果表明,TiO2光催化对SFblue染料废水具有很好的处理效果,用量少、处理浓度高,且在发生光催化降解的同时还伴随着光分解反应,表观反应级数为二级。此外,适当鼓入空气对提高TiO2的光催化效率有一定促进作用。 In this paper,the photocatalytic activity of TiO2 and the influence of various conditions on degradation of concentrated SF blue in wastewater were investigated.The results showed that TiO2 had a high activity on degradation of the SF blue dye with a small amount of TiO2 for treating concentrated dye solution,while the photodecomposition of the dye took place concurrently with the photocatalytic degradation.The results also showed that the degradation was of the second order reaction apparently,and air-blasting in the solution could improve the efficiency of TiO2.
