Abstract Suspencion quantitative method was used to observe the efficacy of chlorine dioxide disinfectant solution generated by the chlorine dioxide generator in killing anisms in water and its influencing :The chlorine dioxide and a 1 min contact time and 5 min contact time respectively could reduce Escherichia coli in water to 0 cfu/ germicidal efficacy increased with increasing water temperature and decreased with anic substances such as humic acid in value of water at ~ had no influence on germicidal efficacy.
Key words chlorine dioxide generator;disinfection of drinking water;Escherichia coli
二氧化氯是国内外公认的高效、广谱、速效的消毒剂,被确认为氯系消毒剂理想的更新换代产品,越来越多的国家已把二氧化氯用于水的消毒[1]。二氧化氯发生器因其设备简单、操作管理方便,消毒过程稳定可靠等优点被广泛应用。高纯二氧化氯发生器以亚氯酸钠和盐酸为原料,在正压条件下,两种原料发生反应,产生以二氧化氯为主的消毒液。产生的消毒液淡黄色,有氯味,总有效氯含量为1367mg/L,,。为了解该消毒液对水中细菌的杀灭效
