| Abstract |
In einem alten französischen Bergwerk, in dem früher Blei und Silber abgebaut wurden, kam es nach dem Wiederanstieg des Grundwassers zu einer erhöhten Schwermetallbelastung von Quellgebieten, die einen Fluß mit Forellenbesatz schädigten. Zur Beseitigung dieser Grundwasserverunreinigung wurde das saure Grubenwasser mit erhöhten Eisen- und Zinkgehalten übertage gefaßt und einer Wasseraufbereitung unterzogen. In der für einen Durchsatz von 100 m(exp 3)/h konzipierten Wasseraufbereitung wurden die Schadstoffbestandteile durch Oxidation und anschließende Neutralisation mit Kalk (Anhebung des pH-Wertes auf 8,2 bis 8,3) gefällt, durch Zugabe eines Flockungsmittels gebunden und die Schlammbestandteile anschließend einem Eindicker und Filterpressen zugeführt. Der Kalkverbrauch wird mit 240 kg/d angegeben. Die tabellarisch zusammengestellten Analysenergebnisse zeigen, daß die Wasseraufbereitung einen sehr guten Wirkungsgrad hatte. Neben einer Anhebung des pH-Wertes von 6,5 auf 8,2 konnten die Schwermetallgehalte bei Fe von 22 mg/l auf 0,09 mg/l und bei Zn von 38 mg/l auf 0,4 mg/l abgesenkt werden. |

| Abstract |
A demonstration project was conducted to investigate treating acid mine water by alkaline injection technology (AIT). A total of 379 t of alkaline coal combustion byproduct was injected into in an eastern Oklahoma drift coal mine. AIT increased the pH and alkalinity, and reduced acidity and metal loading. Although large improvements in water quality were only observed for 15 months before the effluent water chemistry appeared to approach pre-injection conditions, a review of the data four years after injection identified statistically significant changes in the mine discharge compared to pre-injection conditions. Decreases in acidity (23%), iron (18%), and aluminium (47%) were observed, while an increase in pH (0.35 units) was noted. Presumably, the mine environment reached quasi-equilibrium with the alkalinity introduced to the system. |
