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SO42-还原到S2-并释放出碱度,使废水pH值提高,S2-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。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 SO4^2- to S^2- and realease alkalinity, the pH value of the wastewater is increased, meanwhile, S^2- 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.
