人的传染病,尤其是肠道传染病的流行,很多情况是通过水源传播的。野战条件下,水源水质复杂,可能会遇到高浊度、高色度、污染严重的水源,如何为部队提供符合卫生要求的饮用水仍然是亟待解决的问题。集中式给水消毒,国内外以氯为主要消毒剂,而氯能与水中存在的有机物质形成有害于人体健康的卤代化合物、有的还产生异味。目前国内较先进的是利用光辐射进行消毒的紫外线消毒器,但该法要求水源水的浊度小于5度、色度小于15度方可使用,而且对水源中大肠菌群指数和细菌总数都有一定限制(大
Human infectious diseases, especially the epidemic of intestinal infectious diseases, are transmitted through water sources in many cases. Under field conditions, the water quality of the water source is complex and may encounter water sources with high turbidity, high chroma, and serious pollution. How to provide the troops with drinking water that meets the hygienic requirements remains an urgent problem to be solved. Centralized water disinfection, chlorine at home and abroad as the main disinfectant, and chlorine and organic substances present in the water form harmful to human health halogenated compounds, and some also produce odor. At present, the more advanced is the use of UV radiation disinfection of UV sterilizer, but the law requires water turbidity of less than 5 degrees, less than 15 degrees of color can be used, and the water in the coliform index and the total number of bacteria are There are certain restrictions (large
