摘　　要：针对在疫情防控等特殊时期,生活饮用水提高余氯的强化消毒进行试验研究。结果表明:采用氯胺、次氯酸钠和二氧化氯作为消毒剂,当对应的余氯分别在0. 940和0. 812 mg/L,余二氧化氯为0. 456 mg/L时,消毒效果达标且对水质的影响不大,但所产生的的嗅味和成本存在差异。Experiment on increasing residual chlorine to enhance disinfection process in drinking water in the special period of prevention and control of the COVID-19 and similar situations was carried out. The results showed that the disinfection effect could fit the standard and had little impact on the water quality,but there were differences in the odor and cost,when chloramine,sodium hypochlorite and chlorine dioxide were used as disinfectants,and the corresponding residual chlorine was 0. 940 and 0. 812 mg/L respectively,the residual chlorine dioxide was 0. 456 mg/L.
