开发了一个交互式、用户友好的计算机程序来模拟水处理过程中的无机水质变化、THM形成、消毒剂衰减和天然有机物（NOM）去除。本文讨论了该项目中经验模型的选择、开发和验证。具体而言，这些是:总THM和单个THM、去除THM前体（通过总有机碳和紫外线吸收率进行量化）（包括通过明矾凝聚和其他单元过程去除天然有机物）、碱度和pH调节，以及氯和氯胺衰变。概述了进一步的研究需求。该模型的开发是为了帮助美国环境保护局（US Environmental Protection Agency）确定现有处理技术可以达到的消毒剂副产品（DBP）浓度，考虑到微生物安全的要求； 确定DBP控制的最佳可用技术；并提供一种工具来评估新法规对现有处理厂DBP形成的影响。许多方程式、图表和图表补充了本文。

An interactive, user-friendly computer program was developed to simulate inorganic water quality changes, THM formation, disinfectant decay and removal of natural organic matter (NOM) in water treatment processes. The selection, development and verification of empirical models include in the program is discussed. Specifically, these are: total and individual THMs, removal of THM precursors as quantified by total organic carbon and absorbance of UV light (involving removal of natural organic matter by alum coagulation and other unit processes), alkalinity and pH adjustment, and chlorine and chloramine decay. Further research needs are outlined. The model was developed to help the US Environmental Protection Agency determine disinfectant byproduct (DBP) concentrations that can be achieved by existing treatment technologies, given the requirements for microbiological safety; identify best available technologies for DBP control; and provide a tool to assess the impacts of new regulations on DBP formation in existing treatment plants.
