给水处理消毒技术发展展望

消毒技术是给水处理工艺中的重要组成部分 ,而氯消毒是国内外最主要的消毒技术 ,但由于氯消毒产生有“三致”作用的消毒副产物等原因 ,消毒技术的优化和发展成为十分紧迫的问题。目前优化消毒主要包括优化常规的氯消毒和采用其他方式的消毒技术。详细介绍了国内外消毒技术的发展历程 ,比较了氯、二氧化氯、臭氧和紫外线消毒各自的优缺点 ,并指出了给水处理消毒技术的发展方向

Forecast on advanced water disinfection

As an important measure in water purification, chlorination, which had hitherto been routine of water disinfection is being to be doubted due to the disinfection by-products which have potential carcinogenic effects. There are two ways to solve this urgent problem, to improve the chlorination and to create new measures for water disinfection. In this paper the advances in this field home and abroad are presented, especially the chlorine, chlorine dioxide, ozone and ultraviolet processes are compared and the prospects are indicated.
