| 摘 要： | 以荧光活体染色法研究了ClO2浓度、灭活时间、浊度、pH值、温度、有机物含量等,对ClO2灭活隐孢子虫效果的影响,并利用扫描电镜和蛋白质实验初步探究了灭活机理.结果显示,当pH7.0,水温为25℃,浊度为1NTU时,投加3mg/L ClO2经过120min,可以达到最适消毒效果(存活率小于1%),隐孢子虫的灭活率与ClO2投加浓度、作用时间成非线性正相关.浊度是影响ClO2灭活隐孢子虫的主要因素,浊度越低,灭活效果越佳;水温(较)低,灭活效果稍差;酸性较于碱性更适宜ClO2灭活隐孢子虫;可溶性有机物一定程度上影响ClO2的灭活效果.扫描电镜和蛋白试验表明,ClO2主要破坏其细胞表面结构,从而引起隐孢子虫死亡. |

| Abstract: | The fluorescence staining method was used to study the effect of chlorine dioxide(ClO2) inactivating Cryptosporidium in water and affecting factors(ClO2 concentrations,inactivating times,pH values,temperatures,turbidities and organic contents).Then the scanning electron microscopy(SEM) and protein assay were used to investigate cell ultrastructures variation to shed light on the mechanism of inactivation preliminarily.It could achieve the optimum disinfection effect(the survival rate of less than 1%) when a... |
