| 摘 要： | 在参与供水管网余氯消耗的三种因素中,除了主体水和管壁生物膜的消耗外,管壁腐蚀也是不容忽视的因素,尤其在铸铁管中.从微观电化学反应的角度,得到了管壁腐蚀导致的余氯衰减模型,结果与实际情况符合较好.

| Abstract: | In the three parts taking part in the residual chlorine consumption in water supply pipe net,the inner pipe wall corrosion is a part not to be neglected,except the consumption from the water bulk and the inner pipe wall bio-film,especially for the cast iron pipe.From the aspect of micro-electrochemistry reaction,the residual chlorine attenuation model responsible for the pipe wall corrosion was set up,and the results from the model fitted the reality well. |
