Tagebau Ton=Mineral Grubenentwässerung Abwasserbehandlung Absetzbecken |
| Abstract |
In Tontagebauen sammelt man die durch Tonteilchen verunreinigten Niederschlagsmengen am tiefsten Punkt des Tagebaus und pumpt sie zur Reinigung ab, bevor sie dem normalen Wasserkreislauf wieder zugeführt werden. Die sedimentative Reinigung geschieht durch Tagebausumpf, Beruhigungsbecken und Absetzbecken mit Gegenstromprinzip. Im Tagebau Ludwig Hirsch der Firma Fuchs treten saubere, klare Niederschlagswässer oberflächennah am Tagebaurand aus. Sie werden zwischenzeitlich in Betonschächten gefaßt und über den nahen Vorfluter einem Gewässer dritter Ordnung zugeleitet. Damit werden die Erosion der Tagebauböschung verhindert, der Zentralsumpf entlastet und die Verschleißkosten an Pumpen reduziert. Die Pumpenschächte des Klarwassers werden in die Rückverfüllung eingebunden und so ausgebaut, daß langfristig ein störungsfreies Zufließen gewährleistet ist. Zum Schluß der Rekultivierung werden sie verfüllt. |

| Abstract |
The leaching characteristics of sludges from the treatment of acid mine drainage(AMD) from Iron Mountain Mine near Redding, California were compared using two different processes: caustic soda treatment and a modified lime/sulfide treatment process. The modified lime/sulfide process produced a sludge with better dewaterability characteristics than sludge from the caustic soda process. The results of the Cal WET indicated that the modified lime/sulfide process sludge had less leachability than that of sludge from the caustic soda process. Both processes could achieve a substantial reduction of heavy metals in leachate to levels below the federal regulatory limits(TCLP). For cadmium and zinc, however, neither process produced a sludge that met the requirements of the Cal WET procedure. |
