摘要
介绍了纳米TiO2的光催化反应机理,概述了纳米TiO2光催化技术在降解油污废水、农药废水、染料废水、表面活性剂废水、造纸废水、其他有机物废水,以及含重金属废水中的应用研究进展。指出限制纳米TiO2光催化技术实际应用的5个因素:纳米TiO2的改性、纳米TiO2的固定化、纳米TiO2的制备方法、纳米TiO2的应用机理和纳米TiO2的负面影响。科研工作者需不断完善纳米TiO2光催化技术,才能使其在工业废水处理领域得到更广泛和有效的应用。
Photocatalytic reaction mechanism of nano-TiO2 is introduced.The progress in the research on the application of nano-TiO2 photocatalytic technology to the degradation of wastewater containing oil stain,pesticides,dyeing,surfactant,other organic compounds and heavy metals,and wastewater from paper making is reviewed.The five factors that has limited the practical application of nano-TiO2 photocatalytic technology,such as the modification, immobility,preparation method,and application mechanism of nano-TiO2 and their negative influences on the application of nano-TiO2 are pointed out.Researchers should make continuous improvements on nano-TiO2 photocatalytic technology,so as to make its application to the treatment of industrial wastewater become broader and more effective.
