Abstract |
For the treatment of contaminated mine waters reliable treatment methods with low investment and operational costs are essential. Therefore, passive treatment systems recently have been installed in Great Britain and in Germany (e.g. anoxic limestone drains, constructed wetlands, reactive barriers, roughing filters) and during the last eight years such systems successfully treated mine waters, using up to 6 ha of space. In some cases with highly contaminated mine water, a combination of active and passive systems should be applied, as in any case the water quality has to reach the limits. Because not all the processes of passive treatment systems are understood in detail, current research projects (e.g. EU-project PIRAMID) were established to clarify open questions. |

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 |
Agricultural soils irrigated with acidic mine water from the Guangdong Dabaoshan Mine, China, were investigated. The pH of the soils could be as low as 3.9. However, most of the mineral acids introduced into the soils by irrigation were transformed to insoluble forms through acid buffering processes and thus temporarily stored in the soils. Different heavy metals exhibited different fraction distribution patterns, with Zn and Cu being mainly associated with organic matter and Pb being primarily bound to oxides (statistically significant at P = 0.05). Although the mean of exchangeable Cd was greatest among the Cd fractions, there was no statistically significant difference between the exchangeable Cd and the oxide-bound Cd (the 2nd greatest fraction) or between the exchangeable Cd and the carbonate-bound Cd (the 3rd greatest fraction). It was also found that there were generally good relationships between the concentrations of various Zn, Cu, Pb, and Cd fractions and pH, suggesting that a major proportion of each heavy metal in the soils was mainly derived from the acidic irrigation water. The results also show that the crops grown in these soils were highly contaminated by heavy metals, particularly Cd. The concentration of Cd in the edible portions of most crops was far in excess of the limits set in China National Standards for Vegetables and Fruits and this can be attributable to the extremely high transfer rate of Cd from the soils to the crops under the cropping system adopted in the study area. < copyright > CSIRO 2005. |
