摘要 为了研究高纯二氧化氯(ClO2)对水中贾第鞭毛虫的灭活效果,选择荧光活体染色法作为贾第鞭毛虫灭活效果的评价方法,研究不同因素对ClO2灭活贾第虫效果的影响.结果表明:当pH=7.0,水温为25℃,浊度为1NTU,投加2mg/LClO2后30min,可以达到最适消毒效果(贾第虫存活率小于1%);浊度是影响ClO2灭活贾第虫效果的主要因素;贾第虫孢囊的存活率(孢囊含量为3×105个/mL)与ClO2投加质量浓度、作用时间成非线性负相关;酸性较于碱性更适宜ClO2灭活贾第鞭毛虫;可溶性有机物质量浓度一定程度上抑制ClO2的灭活效果. In order to investigate the efficiency of chlorine dioxide on disinfecting Giardia in water,a fluorescence staining method was employed to eveluate the effect of chlorine dioxide inactivating Giardia affected by different factors.The results show that the optimum disinfection effect（the survival rate of less than 1%） can be achieved when adding of 2.0 mg/L ClO2 after 30 min（pH=7.0,25℃ and turbidity of 1 NTU）.Turbidity is one important factor affecting inactivation.The survival rate of Giardia cysts has a non-linear negative correlation with chlorine dioxide concentration and reaction time.The acidic condition is a little better than alkaline condition.Concentrations of organic matter can inhibit the disinfecting effect of ClO2 to some extent.
