Denitrifying up-flow packed bed bioreactors (UPBRs) were evaluated for their capacity to simultaneously remove nitrate and perchlorate from ion exchange regenerant brines. A continuous-flow UPBR, which was inoculated with denitrifying bacteria obtained from a municipal wastewater plant, completely removed perchlorate as well as nitrate in conditions of up to 10% salinity. When nitrate and perchlorate were added to the UPBR, they were removed immediately. To investigate factors that affected the contaminant removal, acetate (as an electron donor) and sulfate (as a competing electron acceptor) were added at different salinities. Lower carbon loading decreased the nitrate and perchlorate reductions, but increased sulfate loading did not decrease the reductions of nitrate and perchlorate. In conclusion, the UPBR is a useful and powerful technology that simultaneously removes nitrate and perchlorate in brine.
反硝化上流式填充床生物反应器（UPBR）用于评估其同时从离子交换再生盐水中去除硝酸盐和高氯酸盐的能力。用从城市污水处理厂获得的反硝化细菌接种的连续流 UPBR 在高达 10%盐度的条件下完全去除了高氯酸盐和硝酸盐。当 UPBR 中添加硝酸盐和高氯酸盐时，它们会立即被去除。为了研究影响污染物去除的因素，在不同盐度下添加了乙酸盐（作为电子供体）和硫酸盐（作为竞争电子受体）。较低的碳负荷会降低硝酸盐和高氯酸盐的还原，但增加硫酸盐负荷不会降低硝酸盐和高氯酸盐的还原。总之，UPBR 是一种有用且强大的技术，可同时从盐水中去除硝酸盐和高氯酸盐。
