passive treatment anoxic limestone drains wetlands sulfate reduction successive alkalinity-producing systems acid mine drainage ALD SAPS RAPS |
| Abstract |
Ten passive treatment systems, located in Pennsylvania and Maryland, have been intensively monitored for up to ten years. Influent and effluent water quality data from ten anoxic limestone drains (ALDs) and six reducing and alkalinity-producing systems (RAPS) have been analyzed to determine long-term performance for each of these specific unit operations. ALDs and RAPS are used principally to generate alkalinity, ALDs are buried beds of limestone that add alkalinity through dissolution of calcite. RAPS add alkalinity through both limestone dissolution and bacterial sulfate reduction. ALDs that received mine water containing less than 1 mg/L of both ferric iron and aluminum have continued to produce consistent concentrations of alkalinity since their construction. However, an ALD that received 20 mg/L of aluminum experienced a rapid reduction in permeability and failed within five months. Maximum levels of alkalinity (between 150 and 300 m&) appear to be reached after I5 hours of retention. All but one RAPS in this study have been constructed and put into operation only within the past 2.5 to 5 years. One system has been in operation and monitored for more than nine years. AIkalinity due to sulfate reduction was highest during the first two summers of operation. Alkalinity due to a limestone dissolution has been consistent throughout the life of the system. For the six RAPS in this study, sulfate reduction contributed an average of 28% of the total alkalinity. Rate of total alkalinity generation range from 15.6 gd''rn-'to 62.4 gd-'mL2 and were dependent on influent water quality and contact time. |

| Abstract |
Das Grundprinzip der Vermeidung einer Säuregenerierung als Quelle für die Freisetzung saurer Grubenwässer ist die Isolation reaktionsfähiger Lagerstättenbestandteile durch Einkapselung, Abdeckung oder Oberflächenversiegelung. Die Hauptzielstellung besteht in der Unterbindung des freien Zutritts von Sauerstoff oder Wasser zu dem reaktionsfähigen Material. Es werden sehr verschiedenartige technologische Möglichkeiten zur Erreichung dieser Zielstellung vorgestellt und bewertet, die eine Präventivfunktion erfüllen und sich daher besonders für neue Aufhaldungen oder Tailingbecken anbieten. Dabei spielt bei der Auswahl des richtigen Verfahrens der Standort eine wichtige Rolle. Es werden auch Vorschläge zur Sanierung alter Halden und Absetzbecken unterbreitet, die vornehmlich auf die Schaffung effektiver Abdeckungen und die Realisierung von Kapselungsvarianten orientieren, aber auch Haldenumlagerungen sowie Wasseraufbereitungsmaßnahmen vorsehen. Es werden Probleme der Materialauswahl für die Abdeckungen zur Gewährleistung einer niedrigeren Permeabilität und einer hohen Langzeitstandsicherheit diskutiert und Fragen der Instandhaltung und des Monitorings behandelt. |
