摘要
在考虑了余氯在管道中与管道水中有机物和无机物的反应，与管壁附着的细菌膜的反应，在管壁腐蚀过程中的消耗及管壁与水流之间余氯的质量传输等影响因素基础上，创新发展了余氛在配水管道中的消耗动力学方程。结合配水管网的水力分析与计算，给出了配水管网中余氛浓度的计算公式。该模型被用于实际的配水管网，计算值与观测值取得了较好一致性。
A model of residual chlorine decay in drinking water distribution system has been developed,with considering the consumption of chlorine as it reacts with chemicals in bulk water, the reaction of chlorine with biofilms on the pipe wall, the consumption of chlorine in the cormsion process, and the mass transport of chlorine form bulk water to pipe wall. The calculation formula of residual chlorine concentration at all nods in an actual distribution system. This model was used to predict the decay of chlorine in an actual distribution system. There ae good agreement between calculated and measured values.
