摘　　要：基于强氧化剂的化学氧化技术是实现难降解有机污染物去除的有效手段。相比臭氧等气态氧化剂和过氧化氢等液态氧化剂,高锰酸盐等固态氧化剂具有寿命长、使用方便、泄漏风险低等优点,在去除水中难降解有机污染物方面极具优势。近年来,为进一步提高固态氧化剂去除难降解污染物的效能,通过添加还原性介体的方法增强氧化剂对有机污染物转化去除得到普遍认可,尤其是其在降解有机新污染物方面展现出的良好强化效能。为了促进该领域全面深入的研究,指导还原性介体强化法在水处理工程中更切合实际的推广与应用,对水处理领域涉及的几种还原性介体与固态氧化剂高锰酸盐、高铁酸盐和高碘酸盐的组合体系进行详细介绍与总结,并对还原性介体强化固态氧化剂体系在实际水处理工程中的应用进行总结与评述。Chemical oxidation technology based on strong oxidants is an effective means to achieve the removal of recalcitrant organic pollutants.Compared with gaseous oxidants such as ozone and liquid oxidants such as hydrogen peroxide,solid oxidants such as permanganate have the advantages of long life,ease of use and low risk of leakage,and have great advantages in removing refractory organic pollutants in water.In recent years,in order to further improve the efficiency of solid oxidants in removing refractory pollutants,it has been widely recognized that the method of adding reducing mediators enhanced the removal of organic pollutants by oxidants,especially in the degradation of emerging pollutants.This paper summarizes the combination systems of several reducing mediators with solid oxidants permanganate,ferrate and periodate involved in the field of water treatment.Then,the application of reducing mediator-enhanced solid oxidant systems in practical water treatment engineering is summarized and discussed.Through the collection and summary works on this topic,it is expected to promote more comprehensive and in-depth basic research and contribute to more practical promotion and application of water treatment engineering.
