紫外线消毒对水处理系统的微生物的杀菌效果研究

Study of Ultraviolet Light on Killing Microbial in Water-treatment System

紫外线消毒是一种有效经济的消毒方法,其能在几秒钟内杀灭病原微生物,并不残留有害物质和不影响水的风味或口感。生产用水中的微生物指标非常重要,本论文通过研究在紫外线杀菌前后,水处理系统中的水所含的大肠杆菌和菌落总数的变化情况。

In the paper the quantity change ofE.coli ＆ total bacterial was studied by ultraviolet light. The result shows that ultraviolet light is an efficient, economic disinfection method. It can kill pathogen microorganisms in several seconds of without leaving any resides and influencing water quality.
