| 摘 要： | 研究了短时游离氯后转氯胺的联合消毒方法对大肠杆菌的灭活作用，并对其协同作用以及pH值和温度对协同作用的影响进行了探讨。结果表明：pH值在6．5～8范围内，温度不超过30℃时，短时游离氯后转氯胺的消毒方法对大肠杆菌的灭活具有协同作用，且随pH值的降低而加强，在低温下该方法的协同效果更加明显。

| Abstract: | The inactivation of Escherichia coli with short-term free chlorine followed by monochloramine was investigated with pH ranging from 6 to 8, temperature ranging from 5 ℃to 30 ℃. The occurrence of synergy in the sequential application of short-term free chlorine and monochloramine and the effects of pH and temperature on synergy were studied. Experimental results showed that the synergy for sequential short-term free chlorine and monochloramine occurred within the range of pH6.5 to 8, temperature less than 30℃. The synergistic effect was found to increase with decreasing pH. Stronger synergy was observed at the lower temperature. |
