浅谈给水工程水体消毒

对当前国内外给水工程中常用的源于漂白粉消毒技术的液氯、二氧化氯和氯胺消毒技术，以及臭氧和紫外线等主要消毒技术进行了比较，简要介绍了各种消毒方法的消毒机理、运行特性，分析、讨论各种消毒技术的特点、适用范围．氯系消毒技术成熟，可单独使用或组合使用；紫外线消毒和臭氧消毒技术由于消毒速度快、有效时间短，可作为联合消毒技术的重要组成部分来应用．另外，探讨了未来给水工程水体消毒技术的发展方向．为给水工程消毒技术方案选择、减小水体消毒有害副产物浓度提供参考．

Introduction to water disinfection in water supply engineering

The essay introduces the disinfection technology of water supply engineering applied at home and abroad, such as liquid chlorine, chlorine dioxide, chloramines disinfection technology,ozone as well as ultraviolet disinfection technology. According to the analysis of the sterilization mechanisms, operation features, characters and applying range of these ways, it has been found that chlorine disinfection is well developed, which can be used alone or in combination, while ultraviolet disinfection and ozone disinfection technologies can be used as an important part of a combined disinfection technology due to its quick disinfection and less effective time. In addition, the essay also talks about ？ the development direction of disinfection technology, providing reference for the choice of various ways of disinfection and reduction of harmful by - product concentration.
