在英国，诺森布里亚水务集团用于生产饮用水的大部分资源 水是以高天然有机物（NOM）浓度为特征的地表水 以及位于农业区时农药的出现。因此，三卤甲烷 （THM）还必须考虑地层风险。在这种情况下，诺森布里亚水域 饮用水供应商必须在其处理厂实施有效流程，以 遵守欧盟现行的三卤甲烷和农药法规（100微克/升和0.1微克/升） 分别）。在为改善现有WTW而测试的不同解决方案中，吸附 在本研究中，对颗粒活性炭（GAC）过滤器进行了测试，以解决这两个问题 以及杀虫剂问题。本文的目的是展示通过这种方法获得的结果 用两种不同方法模拟全尺寸GAC穿透曲线的研究 NOM和异丙隆:快速小型柱试验（RSSCT）；而且，同质的 表面扩散模型（HSDM）。RSSCT方法的主要兴趣在于它能够 在动态条件下，在一到两个月的试验中预测一年的突破曲线。 HSDM方法的主要兴趣在于能够轻松快速地模拟GAC 不同初始NOM和异丙隆浓度或不同 基于相同等温线和动力学台架试验的GAC过滤器特性。 两种方法所得结果的比较显示出良好的相关性。包括6个参考文献、表格、图表。

In the United Kingdom, most of the resources used by the Northumbrian Water group to produce drinking water are surface waters characterized by high natural organic matter (NOM) concentrations as well as by pesticide occurrence when located in agricultural areas. Consequently, the Trihalomethane (THM) formation risk has to be considered as well. In this context, Northumbrian Water drinking water suppliers have to implement efficient processes on their treatment works to comply with the current EU regulation on THM and on pesticides (100 µg/L and 0.1 µg/L respectively). Among the different solutions tested to improve the existing WTW, adsorption on granular activated carbon (GAC) filters was tested within this study to solve both NOM and pesticides issues. The objective of this paper was to present the results obtained by this study by two different approaches to simulate the full scale GAC breakthrough curves for NOM and isoproturon: the Rapid Small Scale Column Test (RSSCT); and, the Homogeneous Surface Diffusion Model (HSDM). The main interest of RSSCT method was its ability to predict a one year breakthrough curve in one to two months test under dynamic conditions. The main interest of HSDM method is the ability to easily and quickly simulate GAC breakthrough curves for different initial NOM and isoproturon concentrations or different GAC filter characteristics based on the same isotherms and kinetics bench scale experiments. The comparison between the results obtained by the two methods shows good correlation. Includes 6 references, tables, figures.
