摘要
以腐殖酸为三卤甲烷形成的前驱物质，确定ＴＨＭ生成的反应级数为二级。引入了ＴＨＭ生成能（ＴＨＭＦＰ）的概念，将ＴＨＭ的生成作为ＴＨＭＦＰ、余氯浓度、滞留时间及温度的函数，提出了三卤甲烷浓度分布的水质模型。利用此模型结合配水管网的水力分析与计算可以求出配水管网中任一节点的ＴＨＭ浓度。三卤甲烷浓度分布的水质模型用于实际的配水管网，其计算值与观测值取得了较好的一致性。
Abstract The humic acid was dosed as the precursor of trihalomethanes(THM) and second order kinetics was identified for the THM formation reaction. The rate of this reaction was formulated as a function of the concentration of the formation energy, residual chlorine concentration, reaction time and reaction temperature. A model of water quality to give the THM concentration distribution was established. To the THM concentration at all nods in drinking water distribution system was estimated by the model together with the hydraulic analysis and calculation of the networks. A good agreement between the calculated and measured values was formed, so it is confirmed that this analysis method is efficient and available to an actual water distribution system comparing with the THM obtained from field surveys.
