摘　　要：介绍纳米TiO2的光催化特性,概述纳米TiO2光催化技术在降解印染废水、农药废水、造纸废水、表面活性剂废水以及含苯酚类、石油类和重金属污染物废水处理中的应用研究进展,总结了纳米TiO2应用于废水工业化处理所存在的问题,认为该技术研究领域近期内的主要发展方向为:大力开展纳米TiO2的改性技术、固定化技术和纳米TiO2光催化降解实际工业有机废水的试验研究及其高效、多功能、集成式光催化反应器的研制。Photocatalytic characteristics of nanometer TiO_2 are introduced. The application of nanometer TiO_2 photocatalytic technology to the degradation of wastewater from dyeing and printing, pesticides, paper making, and surfactant, and the treatment of wastewater containing phenol, petroleum and heavy metals are reviewed. Problems existing are also summarized. It is presented that the development tendency of the technique in recent years includes: experimental study on the modifying and immobility technology of nanometer TiO_2, experimental study on the application of the technology to the treatment of industrial organic wastewater, and the development of photocatalytic reactors of high efficiency, multi-function and integration.
