消毒是饮用水最基本的处理工艺,是保证居民用水安全必不可少的措施之一。在大规模的供水系统中,氯和氯的衍生物消毒是经济有效和应用最广泛的消毒工艺。消毒剂在杀灭水中病菌或微生物和防治疾病的传染方面发挥了重大的作用。但是,在氯化消毒的同时,氯与水中某些有机物质发生化学反应生成一系列危害人类身体健康的消毒副产物。本文就针对此问题讨论了在生活饮用水中消毒剂的使用种类及其副产物的危害性。
Disinfection is the most basic treatment of drinking water, is one of the essential measures to ensure residents’ water safety. In large-scale water supply systems, the disinfection of chlorine and chlorine derivatives is a cost-effective and widely used disinfection process. Disinfectants play a significant role in killing germs or microorganisms in water and preventing the spread of disease. However, while chlorinated, chlorine reacts with certain organic substances in the water to produce a series of disinfection by-products that endanger human health. In this paper, we discuss the use of disinfectants in domestic drinking water and the dangers of their by-products.
