这个内容我印象中在很多指南中都有表述,比如ISPE 水系统中就有提到Ultraviolet lights have been shown to reduce microbial populations in storage and distribution systems. UV energy is germicidal in the wavelengths of 200 to 300 nanometers, which falls below the visible spectrum. UV light de-activates DNA leading to bacteria reduction. A UV light is not a sterilization device, as it is often referred to. The effectiveness of the light will depend on the quality of the water in which it is acting, the intensity of the light, flow rate of water, contact time, and the type of bacteria present.
其中提到紫外有助于帮助控制微生物,但是A UV light is not a sterilization device,不是一个消毒手段。
但是我并不倾向于照搬指南,我更倾向于从原理上表面我的立场,以biofilm(生物膜)举例,储水系统和分配系统中缺乏有效的消毒手段不利于生物膜的控制,生物膜会滋养微生物生长使水系统偶尔不达标,所以需要其他的消毒手段进行控制。
