摘要
[目的 ]观察二氧化氯对霍乱弧菌的杀灭作用。 [方法 ]以本实验室保存的来自病人的O1群和养鳖池O13 9群霍乱菌株作为实验菌 ,按照GB 195 81-1995操作。[结果 ]二氧化氯 2 2 5mg/L和 45 0mg/L作用 2min ,对霍乱弧菌的杀灭率分别达到 99 99%和 10 0 %。有机物的存在会明显降低杀菌率 ;在 pH 6 0和pH 8 5的鱼塘水模拟水样中 ,二氧化氯 2 2 5mg/L作用 2 0min或 45 0mg/L作用 2min ,对霍乱弧菌的杀灭率达 10 0 % ,明显高于水中其它细菌。[结论
Objective] To study on the germicidal efficacy of chlorine dioxide (CD) for killing V cholera [Methods] The experiment strain was O1 and O139 V cholera obtained from patients and the cultivation terrapin pool The experiment was conducted according to GB 19581-1995 [Results] Chlorine dioxide was able to kill 99 99% and 100% V cholera for 2 min respectively in the concentration 22 5 mg/L and 45 mg/L When organism things existing in the water samples, the germicidal efficacy decreased significantly When pH was 6 0 and 8 5 in mimetic water samples of fishpond and CD 22 5 mg/L for 20 min or CD 45 0 mg/L for 2 min, the killing rates to V cholera were 100 % and higher than that to the other germs [Conclusion] Chlorine dioxide is of high disinfectant efficacy and is suitable for the infected area by V cholera, especially for the pools of aquatic product industry
