摘要
通过对不同消毒剂投量、接触时间和ｐＨ值等条件研究，证明ＣｌＯ２灭菌效果优于或相当于液氯。ＣｌＯ２可在广泛的ｐＨ值范围内具有较强的灭菌能力，而液氯仅在ｐＨ６．８～８．５范围内具有较强的灭菌能力。还初步探讨了ＣｌＯ２对细菌的杀灭机理。研究结果表明，ＣｌＯ２是一种优良的替代消毒剂。
Experiments on killing effects of chlorine dioxide(ClO2) on some bacteria in water were proceeded many times. The killing effect of ClO2 Better than or equivalent to that of liquid chlorine was confirmed under various condition such as dosages of added disinfectants,contact times,pH value and so on. The capability to kill bacteria by ClO2 was significant in a vary wide range of pH,but that by liquid chlorine only in the range of pH 6. 8--8.5. Moreover,the mechanism of killing bacteria by ClO2 was tentatively investigated. It was concluded from this work that ClO2 is an excellent alternative disinfectant.
