摘　　要：消毒副产物(DBPs)是饮用水消毒时由消毒剂与有机物或无机离子等前体物反应生成的一类污染物。文中基于水中的DBPs,介绍了臭氧-过氧化氢(O_(3)/H_(2)O_(2))、臭氧-紫外(O_(3)/UV)、臭氧-过硫酸盐、臭氧-超声(O_(3)/US)及催化O_(3)等高级氧化工艺在去除DBPs这一领域的研究现状,比较各个工艺的作用机理、处理性能及优缺点。较传统水处理工艺,O_(3)联用工艺氧化性强、选择性低、高效、环保,具有广阔的应用前景。但O_(3)联用工艺也存在一系列问题,如易受水质影响、O_(3)转化率低、运行成本高等。为此,应研发并优化O_(3)发生装置和技术,提高O_(3)利用率,降低运行成本;对新型催化剂进行专项探索,致力于研究氧化性更强的活性物质;重点研究反应机理及动力学,以及在复杂水质中工艺的适用性,进一步优化工艺条件,推进基于O_(3)高级氧化在水处理领域的工程化应用。DBPs is a kind of secondary pollutants generated by the reaction of disinfectants with organic or inorganic precursors during drinking water disinfection.Focusing on DBPs in drinking water,the classification and the removal of disinfection by-product precursors by O_(3)-H_(2)O_(2),O_(3)-UV,O_(3)-persulfate,O_(3)-US,catalytic ozonation and other AOPs are described in the paper and compare action principle,treatment effect,advantages and disadvantages of each advanced oxidation technology.Compared with the traditional water treatment process,O_(3)-AOPs have strong oxidation,low selectivity,high efficiency and environmental protection,and has broad application prospects.However,O_(3)-AOPs also have a series of problems,such as being easily affected by water quality,low conversion rate,high operating cost,etc.For this reason,O_(3)generating devices and technologies should be developed and optimized to increase O_(3)utilization and reduce operating costs.Through the special exploration of new catalysts,it is committed to the research of active substances with stronger oxidation.Focus on the study of reaction mechanism and kinetics,as well as the applicability of the process in complex water quality,further optimize the process conditions,and promote the engineering application of O_(3)advanced oxidation in the field of water treatment.
