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，证明本研究方法及所提出的水质模型是有效的和可行的
Using humic acid as a precursor to the formation of trihalomethanes, it was determined that the THM-generated reaction order was secondary. The concept of THM generation energy (THMFP) was introduced, and THM generation was used as a function of THMFP, residual chlorine concentration, residence time, and temperature, and a water quality model for trihalomethane concentration distribution was proposed. The THM concentration of any node in the distribution network can be calculated by using this model in combination with the hydraulic analysis and calculation of the distribution network. The water quality model of trihalomethane concentration distribution was used in the actual distribution network, and the calculated values were in good agreement with the observed values. This proves that the research method and proposed water quality model are effective and feasible.
