چکیده :

Acid mine drainage (AMD) is leachate that may occur naturally or be produced at mine sites and tailings deposits. Specifically, acid mine effluent consists of effluents with a very low pH (4.0) and a high concentration of heavy metals. Therefore, it is highly toxic. Due to the impact these wastewaters have on the environment, effective and low-cost methods have been developed for the treatment of acidic mine wastewater. As an important strategy for increasing pH and precipitation of metal ions, there are biological treatment methods in which bioreactors containing biocatalysts such as sulfate-reducing bacteria are used. Considering the application of microbial fuel cells (MFCs) for wastewater treatment, this technology can be an innovative and promising alternative for the treatment of acid mine wastewater. The aim of this study is to investigate the potential of using microbial fuel cells for the treatment of acidic mine effluent and energy production. Studies show that microbial fuel cell technology has a very promising application in water purification with high concentrations of sulfate and heavy metals. It shows a great advantage over other strategies because, in addition to generating energy, it does not require the addition of chemical compounds, so it is self-sustainable.
