In order to treat acid mine drainage (AMD) effectively using sulfate-reducing bacteria (SRB) at high concentration of sulfate and heavy metals, Fe(0) was added to enhance the activity of SRB. When AMD was treated by SRB and Fe(0) at 25 °C, more than 61% of sulfate was removed and the effluent pH was improved from 2.75 to 6.20 during the operation. Cu(2+) was removed effectively with the removal efficiency at 99%, while only 86% of Fe(2+) was removed during the AMD treatment, without conspicuous change of Mn(2+) in the effluent in the process.
为了利用硫酸盐还原菌（SRB）在高浓度硫酸盐和重金属条件下去除酸性矿山废水（AMD），向体系中投加了零价铁（Fe(0)）以增强 SRB 的活性。在 25°C 条件下，当 AMD 与 SRB 和 Fe(0)共同作用时，超过 61%的硫酸盐被去除，出水 pH 从 2.75 提高到 6.20。Cu(2+)被有效去除，去除率达 99%，而在 AMD 处理过程中，只有 86%的 Fe(2+)被去除，Mn(2+)在该过程中没有明显变化。
