Treatment for acid mine drainage |
摘要 |
An apparatus and method for removing contaminating metal ions and sulfate ions from acidic aqueous solution such as waste mine water which features passing the solution between pairs of electrodes, each pair of electrodes impressed with a voltage selected according to specific ion species and then adding chemical agents to raise the pH and form precipitates of the metal and sulfate ions. The precipitate is then separated from the water with settling and filtering steps. Application of a magnetic field is applied during at least the first mixing step.
