| 摘 要： | 为了解两种不同配方二氧化氯消毒剂对水的消毒效果 ,采用滤膜抽滤法对其进行了试验观察。结果 ,以盐酸激活的BF二氧化氯使用剂量为 2mg/L作用 15min ,以柠檬酸激活的QF二氧化氯使用剂量为 4mg/L作用 10min ,均可使实验室污染水样和天然水样中大肠杆菌的杀灭率达 10 0 %。结论 ,BF消毒剂和QF消毒剂均对水中大肠杆菌有较好的杀灭效果 ,但前者二氧化氯用量比后者要低一倍。

| Abstract: | In order to know the efficacy of two chlorine dioxide disinfectants with different formulas in disinfection of water, filter membrane suction method was used for experimental observation. Results: Both BF chlorine dioxide activated by hydrochloric acid at a dose of 2 mg/L with a 15 min contact time and QF chlorine dioxide activated by citric acid at a dose of 4 mg/L with a 10 min contact time killed 100% of Escherichia coli in laboratory contaminated water sample and natural water sample. Conclusion: Both BF disinfectant and QF disinfectant had good killing effect on E. coli in water, but the chlorine dioxide dose of the former was half of that of the latter. |
