本文介绍了为评估离子交换（IX）技术在去除受污染地下水中高氯酸盐方面的应用而进行的测试项目的部分内容。可行性研究包括两个阶段:实验室规模试验，重点是筛选三种IX树脂和评估关键工艺设计参数；并对三种选定的树脂在全尺寸条件下进行了中试试验。所有测试均使用从圣加布里埃尔盆地收集的地下水进行。讨论了每个测试阶段评估的实验条件。在评估的两种强碱阴离子树脂中，疏水性聚苯乙烯和亲水性聚丙烯酸，仅介绍和讨论了聚丙烯酸树脂测试的结果。

This paper presents portions of a testing program conducted to evaluate the application of ion-exchange (IX) technology for the removal of perchlorate from contaminated groundwater. The feasibility study consisted of two phases: laboratory bench-scale testing that focused on the screening of three IX resins and the evaluation of key process design parameters; and, pilot scale testing of three selected resins operated under fullscale conditions. All testing was conducted using groundwater collected from the San Gabriel Basin. The experimental conditions evaluated in each testing phase are discussed. Of the two types of strong-base anionic resins evaluated, hydrophobic polystyrene and hydrophilic polyacrylic, only the results from the polyacrylic resin testing are presented and discussed.
