本文分析了预氯化技术对饮用水安全性的影响,以及提高饮用水的安全性和改进常规预处理工艺的研究进展.预氯化因会增加消毒副产物的生成,其作用不断受到质疑.预臭氧氧化、预高锰酸钾氧化和预氯胺氧化工艺等都在不同程度上对消毒副产物生成起到抑制作用,逐步被用于强化常规工艺.%In this paper, impact of pre-chlorination on the safety of drinking water is analyzed and the progress on improvementof drinking water safety and its conventional pre-treatment processes are reviewed. The pre-chlorination process has being suspecteddue to its by-products produced. Processes such as pre-ozone oxidation, pre-potassium permanganate oxidation and pre-chlorineamine oxidation are gradually used to strengthen the conventional process due to their inhibition effects on by-products in differentdegree.
