摘　　要：光催化氧化法降解染料废水是目前研究的热点。综述了近年来国内外染料废水光催化降解的研究现状及不同催化剂体系对各种染料的降解作用机制。通过对以TiO2 为主的光催化剂在不同光照强度、不同pH、不同染料初始浓度、不同反应器等条件下降解效果的比较 ,论述了其优越性、不足和影响机制。同时 ,指出了光催化降解染料及印染废水技术需要进一步解决的问题。Photo-catalytic degradation of dyes is currently a research focus. Recent progress in photo-catalytic degradation of dyes is reviewed in this article, and degradation of organic pollutants based on various types of photo-catalysts is also summarized. Effects of photo-catalysts (especially TiO 2) at different reaction conditions such as light intensity, pH, original concentration of solution and reactor are compared. The conclusion will provide theoretical basis for future research and industrialization of photo-catalysis technology. In the meantime, the problems of this technology are put forward.
