这篇海报文章提出了一项研究，以更好地识别和量化氯胺衰变机制及其与环境的关系 支持分配系统中的硝化作用。该目标将通过使用干熄焦配水系统水质模型和现场数据来实现 从参与的公用事业公司收集，以及从实验室试点研究收集的数据。 氯胺参与许多反应，在释放的同时减少分配过程中的残留浓度 分配系统中的氨，支持硝化作用。作为试验的一部分，建立了游离氯和氯胺的反应模型 配水系统水质模型，称为综合消毒和水质（CDWQ）模型。CDWQ使用 数据来自新泽西联合水务公司（Woolschlager 2000； Woolschlager等人，2001年）。包括数字。

This poster paper presents a study to better identify and quantify chloramine decay mechanisms and their relationship to supporting nitrification in distribution systems. This objective will be obtained using the CDWQ distribution system water quality model, field data collected from participating utilities, and data gathered from laboratory pilot studies. Chloramines participate in numerous reactions that diminish residual concentrations during distribution while releasing ammonia in the distribution system, supporting nitrification. A reaction model for free chlorine and chloramines was developed as part of a distribution-system water-quality model, called the Comprehensive Disinfection and Water Quality (CDWQ) model. CDWQ was calibrated using data from a year-long distribution system sampling program conducted at United Water of New Jersey (Woolschlager 2000; Woolschlager et al., 2001). Includes figures.
