Experiments of Separating and Featuring an Efficient SRB

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.
