摘要
消毒副产物(DBPs)这类有毒物质给人类健康和生态环境造成了一定危害,其前体物问题也是目前关注的热点,因此,有效去除消毒副产物前体物,降低消毒副产物生成势对提升水质具有重要意义。紫外联用高级氧化技术具有高效、环保无污染等优势,通过氧化消毒副产物前体物的方式来减少其生成量,具有广阔研究前景。文中阐述了消毒副产物前体物的分类以及紫外-臭氧、紫外-过氧化氢、紫外-过硫酸盐等组合高级氧化技术去除消毒副产物前体物的研究进展,比较了各高级氧化技术的作用原理、处理效果及其优缺点,提出了高级氧化技术控制消毒副产物生成势这一领域未来的研究方向及需要解决的问题。
Toxic substances such as disinfection by-product(DBPs)have caused certain harm to human health and ecological environment,and the problem of precursor is also the focus of attention at present.Therefore,it is of great significance to effectively remove the precursor of disinfection by-product and reduce the potential of disinfection by-product formation to improve water quality.Advanced oxidation technology of ultraviolet oxidation has the advantages of high efficiency,environmental protection and no pollution.It has a broad research prospect through the way of oxidizing disinfection by-product precursor to reduce its production of DBPs.The classification and the removal of disinfection by-product precursors by UV-ozone,UV-hydrogen peroxide,UV-persulfate and other advanced oxidation techniques are described in the paper.Comparison of action principle,treatment effect,advantages and disadvantages of each advanced oxidation technology,future research direction and problems to be solved in the field of controlling the formation potential of disinfection by-products by advanced oxidation technology are illustrated.
