In this study, the usefulness of Miex-DOC resin in eliminating organic substances and their fractions from water sources for drinking water was evaluated. The objects of study were samples from three surface water sources and one infiltration water source taken at water treatment plants before treatment in technical conditions. In particular, the effectiveness of removing biodegradable and non-biodegradable fractions as a function of resin dosages and water-resin contact times was evaluated. The ion exchange process with the Miex-DOC resin achieved a high effectiveness in removing aromatic non-biodegradable organic substances, and therefore a reduction in UV254 absorbance. The biodegradable fraction is much less susceptible to removal yet its removal effectiveness allows for a significant reduction in hazards connected with secondary microorganism development. The results of this study indicate the possibility of using ion exchange with the Miex-DOC resin for effective removal of disinfection by-product precursors.
在本研究中，评估了Miex-DOC树脂在去除饮用水水源中的有机物质及其组分方面的有效性。研究对象是在技术条件下，取自三家水处理厂处理前的三个地表水水源和一个渗流水水源的样本。特别评估了作为树脂剂量和水-树脂接触时间函数的可生物降解和不可生物降解组分的去除效果。使用Miex-DOC树脂的离子交换过程在去除芳香族不可生物降解有机物质方面取得了高效，因此降低了UV254吸光度。可生物降解组分的去除难度大得多，但其去除效果可显著降低与二次微生物生长相关的危害。本研究结果表明，使用Miex-DOC树脂进行离子交换可有效去除消毒副产物前体。
