消毒技术去除饮用水中病原微生物的研究进展

Advance in Pathogenic Microorganism Removal in Drinking Water by Disinfection Technologies

饮用水中存在着不同种类的病原微生物,这些病原微生物给人体健康带来危害。本文简要介绍常规消毒技术去除饮用水中病原微生物的研究现状;常规消毒剂仍然是现代饮用水处理工艺使用的主要消毒剂;近些年来,对常规消毒剂联合消毒的协同作用和联合消毒剂的概念提出了探讨,认为联合消毒剂是今后饮用水去除病原微生物的发展趋势;膜技术这种物理消毒技术,由于其高效性而得到广泛关注,膜消毒去除病原微生物也成为当今消毒技术研究的热点。

There are different species of pathogenic microorganisms in drinking water that do harm to human health. In this paper the advances in removal of pathogenic microorganism in drinking water by conventional disinfection technologies is briefly introduced. The conventional disinfectants are still dominant reagents for drinking water treatment. In recent years, the synergy of disinfection of pathogenic microorganisms using multiple conventional disinfectants combined and the concept of disinfection combination are discussed. It suggested that application of combined disinfectants is the developing tendency for removal of pathogenic microorganisms in drinking in future. Besides, the membrane technology, as physical disinfection, becomes a hot spot in the field of removing pathogenic microorganisms due to its high efficiency.
