pH stream mine drainage remediation zinc copper sodium hydroxide USa Montana Beartooth Mountains Fisher Creek 3 Geology |

Abstract |
Fisher Creek, a stream affected by acid mine drainage in the Beartooth Mountains of Montana, was studied to determine the extent to which copper (Cu) and zinc (Zn) would be removed from stream water when pH was increased by a pulse of sodium hydroxide (NaOH). Although the pH adjustment study indicated that precipitated Fe(OH) “SUB 3” (am) could rapidly remove Cu and Zn from a stream affected by acid mine drainage, the pH should be maintained in an optimal range (7 to 8.5) to maximize removal by adsorption. -from Authors |

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. |
