摘要
二氧化氯(ClO_(2))处理饮用水生成的无机消毒副产物亚氯酸盐(ClO_(2)(-))和氯酸盐(ClO-3)对人体健康有潜在危害,引起了世界范围的强烈关注。目前,国内外对控制ClO_(2)无机消毒副产物已有广泛研究。文章总结了ClO_(2)无机消毒副产物的各类来源,并针对性从发生器优化、反应过程控制以及生成后去除3方面,详细讨论了饮用水ClO_(2)无机消毒副产物的控制研究进展。文中提出在源头控制中“优选反应器、优化杂氯”,在消毒过程中“多种方式结合”,以控制无机消毒副产物的生成。此外,消毒后可使用活性炭、Fe^(2+)、硫化物、氧化法等技术去除无机消毒副产物。最后总结了当前研究存在的问题,并展望了未来研究的发展方向。
Chlorite(ClO_(2)(-))and chlorate(ClO-3),the inorganic disinfection by-products(DBPs)produced by chlorine dioxide(ClO_(2))treatment of drinking water,are potentially harmful to human health,which have attracted worldwide attention.At present,the control of ClO_(2)inorganic DBPs has been extensively studied at home and abroad.This paper summarizes the various sources of ClO_(2)inorganic DBPs and discusses in detail the research progress on the control of ClO_(2)inorganic DBPs in drinking water from three aspects:generator optimization,reaction process control,and post generation removal.It is proposed to optimize reactors and impurities in source control,and combine multiple methods during disinfection to control the generation of inorganic DBPs.After disinfection,technologies such as using activated carbon,Fe^(2+),sulfide,and oxidation are used to remove inorganic DBPs.This paper summarizes the current research issues,and in addition,the problems in current research and the focus of future research have been put forward.
