| 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生态能（ＴＨＭＦＰ）的概念，将ＴＨＭ的自下而上作为ＴＨＭＦＰ、余氯浓度、滞留时间及温度的函数，开创性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，计算值与观测值取得了较好４的一致性，证明了本研究方法及所提出的水 |

| Abstract: | The humic acid (HA) was used as the precursors of trihalomethanes(THM), the overall reaction order is second - order. THM formation rate was formulated as a function of the concentration of THMFP. residual chlorine concentration. reaction time and reaction temperature. A model of estimating the THM concentration at all nods in drinking water distribution system was established. There are good agreement between calculated and measured values, 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. |
| Keywords: | trihalomethanes humic acid THM formation potential model of water quality |
