饮用水消毒副产物控制研究进展

Research Progress in the Control of Disinfection By-Products in Drinking Water

近年来广泛应用的氯消毒技术产生的卤代消毒副产物问题突出,由氯胺消毒、臭氧消毒等引入的新型副产物——亚硝胺类物质危害性更甚。消毒副产物的存在影响了饮用水的安全性并引起公众关注。简述了卤代消毒副产物及亚硝胺类副产物的产生,总结了近年卤代消毒副产物及NDMA的控制技术,并对日后饮用水消毒副产物控制研究提出展望。

Problems about halogenated disinfection by-products that produced by the widely used chlorination disinfection were prominent in recent years. Nitrosamines, a kind of new disinfection by-products that caused much harm were brought in drinking water by using chloramine disinfection and ozone disinfection. The existence of disinfection by-products had negative effects on the safety of drinking water and aroused public concern. The formation of halogenated disinfection by-products and nitrosamines was briefly described, while the control techniques of halogenated disinfection by-products and NDMA were summarized. Finally, prospects of the control of disinfection by-products for drinking water were put forward.
