摘要 为了解决自来水厂应用二氧化氯导致的消毒副产物亚氯酸盐、氯酸盐超标问题,对亚氯酸盐生成量与二氧化氯投加量相关性进行了测定分析,开展了以次氯酸钠替代二氧化氯消毒,同时保留二氧化氯预氧化生产性实验。结果表明,亚氯酸盐生成量与二氧化氯投加量显著相关,因此,采用二氧化氯预氧化与次氯酸盐消毒联用,既保证了水质消毒效果,又使水中亚氯酸盐的浓度大幅度降低并稳定达标。 For reducing the generation of chlorites,which is the harmful by-product of chlorine dioxide used as a disinfectant in the water treatment process,relations were studied between chlorites production and dosing rate of chlorine dioxide,as well as retention.Moreover,experiments were carried out bye using chlorine dioxide as per-oxidation and combined with sodium hypochlorite as disinfection alternative to chlorine dioxide.It showed that the generation rate of chlorites was,directly related with dosing rate of chlorine dioxide,but obviously irrelevant both.Combined dosing with chlorine dioxide and sodium hypochlorite ensured the disinfection effect and significantly reduces the amount of chlorite,in addition the treated water stably reached the water quality standard.
