摘要

Iron oxidation, hydrolysis and settling are key processes promoted in passive treatment system to remove iron from influent acid mine drainage (AMD). For net alkaline mine waters, an initial oxidation cell is typically used to remove and store large amounts of precipitated iron oxyhydroxides prior to water flowing through additional wetland treatment cells. Regular monitoring of influent and effluent is suitable to determine overall decreases in iron concentrations due to treatment. However, a detailed analysis of iron removal within specific zones of the oxidation cell provides additional information about performance and functionality. The purpose of this study was to investigate progressive iron removal with increasing distance from the influent AMD discharge and depth in a U-shaped oxidation pond receiving ferruginous lead-zinc mine drainage at the Tar Creek Superfund Site.
