为了深入了解某市饮用水消毒过程对水嗅味的影响,取某净水厂臭氧活性炭后出水,并对其采用不同的消毒方式,包括常规消毒(次氯酸钠消毒、氯胺消毒、二氧化氯消毒)、顺序氯化消毒、二氧化氯和次氯酸钠联合消毒、紫外和氯胺联合消毒以及紫外和二氧化氯联合消毒,对消毒后的水采用嗅味层次分析法进行了嗅味分析评价,结果表明:氯胺消毒和顺序消毒对嗅味的控制较好,次氯酸钠和二氧化氯在投加比为1∶1和3∶1时对嗅味有一定的控制作用。紫外联合消毒,对嗅味也降低作用,但作用比较微弱。
In order to gain a better understanding of the influence of drinking water disinfection process on the smell of water in a certain city, water was taken from ozone-activated carbon in a water treatment plant and different disinfection methods were adopted, including conventional disinfection (sodium hypochlorite disinfection, chloramine disinfection and chlorine dioxide disinfection ), Followed by chlorination disinfection, chlorine dioxide and sodium hypochlorite disinfection, combined UV and chloramine disinfection and UV and chlorine dioxide disinfection, disinfection of water using the smell level analysis of odor analysis and evaluation results show : Chloramine disinfection and sequential disinfection on odor control is better, sodium hypochlorite and chlorine dioxide at the dosing ratio of 1: 1 and 3: 1 when the odor has a certain degree of control. UV disinfection, but also to reduce the role of smell, but the effect is relatively weak.
