摘要：
Acid mine drainage (AMD) causes several environmental problems in many countries. The use of biological processes with sulphate-reducing bacteria (SRB) has great potential within environmental biotechnology. The aim of this study was to develop a bioremediation system, using a mixed culture of SRB, for the treatment of AMD from Sao Domingos mine. Sulphate and heavy metals (Fe, Cu and Zn) concentrations, pH and Eh were monitored during 243 days. The process that was developed consisted of two stages that proved highly efficient at AMD neutralization and the removal of sulphates and the heavy metals iron, copper and zinc.
