| 摘 要： | 含高浓度硫酸盐酸性矿山废水的污染是一个全球性的问题。利用硫酸盐还原菌（SRB）可对含硫酸盐的酸性矿山废水进行生物处理．在厌氧条件下．SRB以碳源为电子供体将SO4^2-还原到S^2-并释放出碱度，使废水pH值提高．S^2-可用物化法或生化法从废水中除去。文章综述了SRB的特点及它的生长条件，重点分析了利用SRB处理酸性矿山废水中存在的问题，如碳源、生物反应器的选择，并对生物处理酸性矿山废水的技术进行了展望。

| Abstract: | The pollution of acid mine drainage(AMD) containing high concentration sulfate is a global problem.AMD containing sulfate can be biologically treated by sulfate-reducing bacteria(SRB).Under anaerobic condition,SRB use carbon source as electron donor,which reduce SO42-to S2-and realease alkalinity,the pH value of the wastewater is increased,meanwhile,S2-can be removed by means of physical chemistry or bio-chemistry.The characteristics of SRB and its growth conditions were summarized,the problems existing with the AMD treatment by SRB such as: selection of carbon source and reactor were specially analyzed,and the prospect of the technology of acid mine drainage biological treatment was also made. |
