| Abstract |
A simulation model is developed of the efficiency and economics of an application of ecotechnology – using a created wetland to receive and treat coal mine drainage. The model examines the role of loading rates of iron on treatment efficiencies and the economic costs of wetland versus conventional treatment of mine drainage. It is calibrated with data from an Ohio wetland site and verified from multi-site data from Tennessee and Alabama. The model predicts that iron removal is closely tied to loading rates and that the cost of wetland treatment is less than that of conventional for iron loading rates of approximately 20-25 g Fe m “SUP -2” day “SUP -1” and removal efficiencies less than 85%. A wetland to achieve these conditions would cost approximately US$50 000 per year according to the model. When higher loading rates exist and higher efficiencies are needed, wetland systems are more costly than conventional treatment. -Authors |

Bergbau Uranerz Grubenentwaesserung Chemische-Abwasserreinigung Asche Calciumcarbonat Verrieselungsfeld Dekontamination |
| Abstract |
Kontaminierte Grubenwässer des Uranbergbaus in Sachsen und Thüringen weisen eine regional schwankende chemische Zusammensetzung auf (Härte: 50 bis 1500 (Grad) dH, Sulfat: 2 bis 30 g/l, Eisen: 0,5 bis 4 g/l, Uranium: 1 bis 20 mg/l). Eine erfolgreich praktizierte Technologie der Abwasserreinigung ist dessen Verrieselung auf Kraftwerksaschen, die auf dichtem Untergrund bzw. dort, wo eine Grundwasserkontamination auszuschließen ist, aufgehaldet werden. Ziel ist es, den Nutzungsgrad der Asche zur Sicherung des Gewässerschutzes zu erhöhen. Eine geeignete Technologie ist dabei auch die Mischung von Asche und Kalk. Da die berieselte Asche bei der Einwirkung von natürlichen Niederschlägen ihre Kontamination teilweise wieder freisetzt, werden an die Verwahrung sowie Deponiebeschaffenheit von Aschehalden besondere Anforderungen gestellt. So muß beispielsweise die Verdunstung erhöht (Bewuchs, Vegetation) sowie die Dränage der infiltrierte Wässer verzögert werden. |
