摘　　要：介绍了目前最重要的商用高级氧化工艺之一的UV/H_2O_2工艺,叙述了UV/H_2O_2工艺动力学研究进展,认为目前此方面的研究仍有所欠缺,鉴于此,将分别从动力学参数及动力学模型2方面对UV/H_2O_2工艺降解污染物的动力学特性进行了探讨。以UV曝辐量为主线,分别阐述并比较了不同反应器中UV曝辐量的测定、基于UV光量子剂量的动力学参数及动力学模型等,指出了UV曝辐量对于光化学反应的重要性,分析表明该模型的建立对单一目标污染物的模拟和预测有较好效果。认为需进一步探讨研究,找到最适合的动力学模型;还应开发高效低耗的新型光源、反应器。The UV/H2O2 process,one of the most important commercial advanced oxidation processes was introduced,and the research progress of UV/H2O2 process kinetics was described,it is considered that there is a lack of research in this area.In view of this,the kinetics characteristic of pollutants degradation by UV/H2O2 process was discussed in two aspects:kinetic parameters and kinetic models.Taking UV exposure radiation as the main line,the determination of UV exposure radiation in different reactors,the kinetic parameters based on UV light quantum dosage and the kinetic model were respectively described and compared.The importance of UV exposure radiation for photochemical reaction was pointed out.The analysis indicated that the establishment of model has a good effect for a single target pollutant simulation and prediction.It is considered that further research is needed to find the most suitable kinetic model and new light source and reactor with high efficiency and low consumption should be developed.
