饮用水二次消毒方法评析与择优

对典型的氯化、二氧化氯、次氯酸钠、臭氧、紫外线和微电解等水的主要消毒技术与工艺，在灭菌可靠性，产物毒副性，管理安全性，操作方便性，经济适用性等方面进行了评价与分析，并对适用于居住区生活饮用水二次消毒技术和工艺进行了择优与探讨，认为紫外线灭菌具有高效、安全、经济等特点，可作为饮用水二次消毒首选方案，微电解消毒具有较高的灭菌效果，持续灭菌能力和方便安全等特点，作为饮用水二次消毒技术具有潜在、广阔的开发与应用前景。

Analysis and Optimization of Drinking Water Second Disinfecting

The main technique and process of water disinfecting including chlorine,chlorine oxide,sodium hypochlorite,ozone,UV,micro-electrolysis were introduced in this paper. A profound analysis of their antimicrobial reliability,deleterious by-product,safe management,convenient operation,ecnomic suitability,optimize,the technique and process of dyinking water second disinfection was done. UV disinfection was the best proposal of drinking water second disinfecting,because of its high efficiency,safety and economy;Dinsinfection by micro-electyolysis was high efficiency,had the power of continuance dinsinfection, was safe and convenient,it had a potetid and wide future in development and applicability.
