Abstract: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.
Keywords:nanometer TiO_2  photocatalytic degradation  industrial wastewater
