摘　　要：Ti O2光催化技术既可应用于难降解废水的预处理,提高废水的可生化性;同时,该技术还可应用于难降解废水经生化处理后的深度处理、以及微污染饮用水的处理。本文介绍了Ti O2光催化氧化的基本原理及在水处理中的应用研究进展。其中主要介绍Ti O2光催化氧化技术在染料废水、垃圾渗滤液、表面活性剂废水、制药废水等的应用,并简述了近年来该技术在国内外的应用实例。TiO2 photocatalytic technology can be applied to the pretreatment of refractory wastewater to improve the biodegradability. At the same time,the technology can also be applied to the depth of the refractory wastewater after biochemical treatment process,as well as the slightly polluted water treatment. The basic principle of TiO2 photocatalytic oxidation technology and its application in water treatment were introduced. The application in the dye wastewater,waste leachate,the surfactant wastewater and pharmaceutical wastewater of TiO2 photocatalytic oxidation technology were mainly introduced. The application examples of this technology were briefly introduced at home and abroad in recent years.
