本研究对生物和化学还原过程、膜过程和离子交换进行了研究，以通过离子交换和化学还原去除高氯酸盐。本研究的重点是高氯酸盐的生物还原。还原过程基于高氯酸盐在热力学上不稳定的事实。本研究的三个主要目标是:确定Norit GAC对高氯酸盐的离子交换能力；确定使用生物活性炭（BAC）过滤可将低:g/L浓度的高氯酸盐生物去除至低于检测限（2.0:g/L）； 确定硝酸盐浓度和高氯酸盐去除水平之间的相关性。包括7个参考文献，表1。

Biological and chemical reduction processes, membrane processes, and ion exchange were investigated in this study for perchlorate removal via ion exchange and chemical reduction. The focus of this research is the biological reduction of perchlorate. Reduction processes are based on the fact that percholorate is thermodynamically unstable. The three primary objectives of this research were: to establish the ion-exchange capacity of Norit GAC for perchlorate; to establish that perchlorate at low : g/L concentrations can be biologically removed to below the limit of detection (2.0 : g/L) using biologically active carbon (BAC) filtration; and, to determine a correlation between nitrate concentration and level of perchlorate removal.
