Abstract: The water treatment performances of two anoxic limestone drains (ALDs) were evaluated. Anoxic limestone drains are buried beds of Limestone that are intended to add bicarbonate alkalinity to flow-through acid mine drainage. Both ALDs received mine water contaminated with Fe2+ (216-279 mg L(-1)) and Mn (41-51 mg L(- 1)). Flow through the Howe Bridge ALD increased alkalinity by an average 128 mg L(-1) (CaCO3 equivalent) and Ca by 52 mg L(- 1), while concentrations of Fe, K, Mg, Mn, Na, and SO42- were unchanged. The Morrison ALD increased alkalinity by an average 248 mg L(-1) and Ca by 111 mg L(-1). Concentrations of K, Mg, Mn, and SO42- all decreased by an average 17%, an effect attributed to dilution with uncontaminated water. Iron, which decreased by 30%, was partially retained within the Morrison ALD. Calcite dissolution was enhanced at both sites by high P- CO2. Untreated mine waters at the Howe Bridge and Morrison sites had average calculated P-CO2 values of 6.39 kPa (10(- 1.20) atm) and 9.24 kPa (10(-1.04) atm), respectively. At both sites, concentrations of bicarbonate alkalinity stabilized at undersaturated values (SICalcite = 10(-1.2) at Howe Bridge and 10(-0.8) at Morrison) after flowing through approximately half of the limestone beds. Flow through the second half of each ALD had little additional effect on mine water chemistry. At the current rates of calcite solubilization, 17.9 kg d(-1) CaCO3 at Howe Bridge and 2.7 kg d(-1) CaCO3 at Morrison, the ALDs have theoretical effective lifetimes in excess of 20 yr. By significantly increasing alkalinity concentrations in the mine waters; both ALDs increased metal removal in downstream constructed wetlands.

Abstract: Überblick über einschlägige Verfahren zum Ausfällen der sauren Betandteile, Entfernen der Schwermetalle, und Einstellen des pH-Wertes auf einen Wert von 6 bis 9. Hauptsächliche Verfahren zum Ausfällen sind: Ausfällen mit Kalkhydrat (Ca(OH)2), mit Kalkstein, Calcium- oder Natriumsulfid. Durch Abtrennen des Niederschlages in einem Kläreindicker und zusätzliche Reinigung durch Filtrieren kann ein Anteil von 90% der unlöslichen Schwermetallverbindungen entfernt werden. Allgemein wird mit diesem Verfahren ein Standardgehalt von 5 mg/l erreicht. Durch zusätzliche Anwendung physikochemischer Verfahren kann der Schwermetallgehalt weiter gesenkt werden: Mikrofiltration, Umkehrosmose, Elektrodialyse, Ionenaustausch, biochemische und spezielle chemische Verfahren können je nach Eigenart der Grubenwässer verwendet werden.
