次氯酸钠现场生产系统在大中型水厂的应用

介绍了次氯酸钠现场生产系统的技术原理和在上海长兴水厂的应用，并与其它几种饮用水消毒手段：投加氯气、二氧化氯、商品次氯酸钠、臭氧以及紫外线照射进行了比较。表明次氯酸钠现场生产技术与液氯或商品次氯酸钠消毒技术相比，是一种无论在原料运输、制备、贮存、投加方面都很安全并有良好即时和持续消毒效果的技术，在经济性方面也比商品次氯酸钠技术优越，次氯酸钠现场生产技术较为适合于大中型自来水厂消毒。

Application of On-Site Sodium Hypochlorite Production System in Large and Medium Size Waterworks

Principal of the on-site sodium hypochlorite production system and the application of this technology to Changxing water plant, Shanghai were introduced. The disinfection method among chlorine, chlorine dioxide, sodium hypochlorite, commerical hypochlorite, ozone and UV radiation were compared. Compared with liquid chlorine and commercial bypochlorite, on-site sodium hypochlorite production technology is a safe technology in raw material transportation, hypochlorite production, storage and dosing. As the on-site hypochlorite produced has a good effect and residual disinfection and it＇s savable, it is more suitable for large and medium size water plants disinfection.
