随着经济的发展和人们生活水平的不断提高,废水的排放量不断增加,相应对水环境的污染也日渐严重,主要表现在污染类型的多样化和有机污染程度的加深,同时也使得水处理的难度不断加大.对于一些难于生物降解的毒性物质可使用强氧化剂将其氧化分解,降低污染程度.以芬顿试剂(Fe2+和H2O2)为主的系列高级氧化技术在水处理中得到了越来越广泛的应用,展示了较高的去除难降解有机污染物的能力.%Emissions of wastewater continued to increase with the development of economic and people's living standards.Environment pollution became more and more serious with the diversification of pollution types and organic pollution, and it was difficult to deal with by conventional process.Oxidant with strong oxidation ability were used to deal with some toxic substances which were difficult to be biodegradable.Advanced Oxodation Process such as Fenton Process were widely used to deal with organic wastewater which was bio-refractory because of their strong oxidizing ability.
