摘　　要：基于臭氧的高级氧化工艺是常见的水处理手段之一,如今已存在大量关于臭氧联用氧化技术的机理研究。由于水中污染物的复杂多样性以及副产物问题,缺乏对氧化技术的系统研究和全面评估,落实到实际应用中较为困难。文章综述了臭氧联用氧化技术的研究现状、去除机理和存在问题,讨论了氧化过程中涉及的自由基机理和自由基的贡献度问题。此外,针对非均相臭氧/过一硫酸盐氧化技术,分析了氧化体系中的溴化副产物问题以及催化剂材料的研究现状。文章指出控制溴化副产物是影响氧化技术实际应用的关键问题,未来需要深入研究溴酸盐的生成和抑制机理、氧化技术的成本效益以及工程适用性等问题。另外,还需优化氧化技术以期达到既能有效降解污染物又能显著抑制溴酸盐的目的,为进一步实际应用提供良好的理论基础和展望。Advanced oxidation processes(AOPs)based on ozone is one of the common water treatment methods.There are a lot of studies on the mechanism of ozone combined oxidation technologies.Due to the complex diversity of pollutants in water and the problem of by-products,there is a lack of systematic research and comprehensive evaluation of oxidation technologies.Therefore,it is more difficult to implement in practical application.This review describes the research status,removal mechanism and existing problems of combined ozonation technologies.The mechanism of free radicals involved in the oxidation process and the contribution of free radicals are discussed.In addition,for the heterogeneous ozone/peroxymonosulfate(Os/PMS)oxidation technology,the bromination by-products in the oxidation system and the research status of catalyst materials were analyzed.In the review,it is pointed out that the control of brominated by-products is a core problem affecting the practical application of oxidation technology.The mechanism of bromate formation and inhibition,the cost effectiveness of oxidation technology and engineering applicability should be further studied in the future.The aim of optimizing oxidation technology is to achieve not only effective degradation of pollutants but also significant inhibition of bromate,which will provide a reliable theoretical basis and prospect for further practical application.
