饮用水的消毒方法分析探讨

Analysis on the Disinfection Method of Drinking Water

水是生命之源,水质安全在社会发展中发挥着重要作用,水处理是一个非常重要的工作,消毒是水处理一个非常重要的环节。文章着重介绍了饮用水常用的几种消毒方法:氯气消毒法、臭氧消毒法、二氧化氯消毒法、氯胺消毒法和紫外线消毒法;阐述了各种消毒方法的消毒机理,工作环境的要求;分析了各种消毒方法的消毒效果和消毒成本;探讨了消毒后水中存留的副产物以及这些副产物对人体的影响。同时提出一些饮用水未来的消毒方法:高锰酸钾消毒、Ti O2光催化消毒、膜消毒、电化学氧化消毒、生物活性炭消毒以及一些联合消毒方法,如高锰酸钾与氯联合消毒、紫外线与氯联合消毒等。

Water is the source of lives, which quality security plays an important role in social development. The water treatment is a very important process, of which the disinfection is a key procedure. This paper emphatically introduces some frequently-used disinfection methods of drinking water： chlorine disinfection method, ozone disinfection method, chlorine dioxide disinfection method, chloramine disinfection method and ultraviolet disinfection method; explains the mechanism of various disinfection methods and their work environment requirements; analyzes the effect of sterilization and disinfection cost; discusses the left by-products and their impacts to the human body. Meanwhile, some impossible disinfection methods of drinking water are put forward： potassium permanganate disinfection, TiO2 photocatalytic disinfection, membrane disinfection, electrochemical oxidation disinfection, biological activated carbon disinfection, and some combination disinfection methods, such as potassium permanganate and chlorine disinfection, ultraviolet ray and chlorine disinfection etc.
