| 摘 要： | 饮用水系统生物膜形成和控制是当前研究的热点。系统阐述了饮用水系统中生物膜的形成和影响成膜的各种因素。生物膜控制技术包括降低有机物含量、物理方法、消毒剂、酶试剂控制、分散剂、紫外线消毒等。饮用水系统中生物膜对剥离剂和紫外线具有抗剥离能力,500mg/L的常规剥离剂也难以剥离成熟的生物膜,紫外线对生物膜中微生物杀灭能力明显弱于对溶液中微生物的杀灭作用。采样结果表明:饮用水管道内部存在严重的微生物污染。一旦生物膜形成,其将紧紧附着于管道内壁。控制饮用水系统中生物膜,降低微生物安全风险,对保证安全供水将具有重要的意义。

| Abstract: | Formation and control of biofilm in drinking water system has been a hot topic in these years. The formation process of biofilm and affecting factors that influence the growth of biofilm are demonstrated. The control technologies of biofilm include reduction of organic matter,physic methods,disinfectants,enzymes,dispersant,UV disinfection and so on. Biofilm formed in natural water can resist chemical release agent and UV. Traditional methods can't effectively remove mature biofilm in drinking water system,e... |
