| 摘 要： | 分别研究了游离氯和一氯胺在pH7.0、20℃时对大肠杆菌的灭活作用,利用6种不同消毒动力学模型:Chick’slaw,Chick-Watson,Hom,Rational,Hom-Powerlaw,Selleckmodel对试验数据进行了拟合,通过对拟合结果的比较分析得出:在消毒剂符合一级衰减动力学情况下,游离氯和一氯胺灭活大肠杆菌的最佳拟合模型分别是3参数的Rational模型和2参数的Selleck模型.

| Abstract: | The inactivation of Escherichia coli with free chlorine and monochloramine was studied using bench-scale experiments in 0.03mol/L phosphate buffered saline with pH 7.0 and at 20. Inactivation data were fitted to Chick's law, Chick-Watson, Hom, Rational, Hom-Power law, Selleck model. A three-parameter Rational model incorporating a first-order disappearance term for free chlorine residual was found to best describe the observed inactivation of E. coli, and for monochloramine the two-parameter Selleck model was the best fit model. |
