Plant effects on microbial assemblages and remediation of acidic coal pile runoff in mesocosm treatment wetlands

摘要: Constructed treatment mesocosm wetland systems comprised of an anaerobic followed by two aerobic wetlands and differing in composition (real plants, plastic no plants) order (shallow deep or vice versa) were compared to determine if affect remediation acidic, metal contaminated water associated with a coal-fired power plant. Aerobic cell was varied native plants have function, are only structure for bacteria, improve quality. The cells increased pH from 2.4 6.4 reduced Al, Fe, Zn 93–99%. Order the did not Cells real versus had different bacterial assemblages, but these clearly related quality differences between tank types. lower NH4 higher Fe Mn, especially during growing season, than those without plants. We conclude that do quality, part because they assemblages. Planted can help remediate metal-contaminated water, may contribute greater Mn concentrations effluent.
