Acid Mining Drainage

This study describes a new method to treat acid mine wastewater containing high amounts of heavy metals and sulfate by biotechnology. Sulfate reducing Bacteria (SRB) was inoculated in an up-flow multiple bed bioreactor treating practical wastewater. In addition to precipitation processes, water purification was also possible with the metabolism process of microorganisms. Iron dust was added to the system to enhance the activity of SRB and ensure the treatment efficiency. The results indicates that treating acid mining drainage using SRB and iron at room temperature (20°C~25°C) is possible, the reduction rate of sulfate is up to 61%, pH of wastewater raises from 2.75 to 6.2 and the copper concentration of effluent is less than 0.2 mg/L.

By experiments, separate and purify efficient sulfate—reducing bacteria (SRB), which is identified as Desulfobacter. With its treatment of acid mine drainage(AMD) containing Fe2+ and Mn2+, obtain the optimum conditions that pH=6,temperature=37,vibrating intensity=100r/min, COD/SO42- =2.Under this condition ,the removal rate of SO42-、Fe2+ and Mn2+ is 88.16%、99.37% and 59.18% respectively with the initial concentration 1411mg/L for SO42-,257mg/L for Fe2+ and 325mg/L for Mn2+.This puts a theoretical foundation for the further study.
