Carbon amendments for the reduction of selenium within saturated waste rock environments at Brule Coal Mine, B.C. (version 2)

不列颠哥伦比亚省东北部的煤矿开采活动可能产生可溶性硒含量高的废水。在将废水排放到环境中之前，需要降低硒浓度。这个以实验室为基础的硕士项目将研究一种生物方法，该方法利用天然微生物将可溶性硒转化为固体形式，有效地去除矿山废水中的硒。在化学还原硒之前，需要通过反硝化去除可溶性硝酸盐。两种不同的碳源将检验其产生适当环境条件去除硒（和硝酸盐）的功效。本研究的结果将有助于矿山设计现场规模的生物电池反应器，用于去除矿山废水中的可溶性硒（和硝酸盐）。研究结果还将有助于Brule矿的硒管理工作，并可能导致比传统管理策略更具成本效益的操作规模技术。

Coal mining activities in northeastern B.C. may generate waste water effluents that are high in soluble selenium. Selenium concentrations need to be reduced prior to the release of effluents to the environment. This laboratory-based MSc project will examine a biological method that uses natural-occurring microbes to convert soluble selenium into solid forms, effectively removing selenium from mine effluents. The removal of soluble nitrate through denitrification is required prior to the chemical reduction of selenium. Two different carbon sources will be examined for their efficacy of producing the appropriate environmental conditions for selenium (and nitrate) removal. The results of this study will aid the mine in designing field-scale biocell reactors for the removal of soluble selenium (and nitrate) from mine effluents. The results will also aid in the Brule mine's selenium management efforts and could lead to operational-scale technologies that are more cost effective than traditional management strategies.
