摘　　要：综述了目前微生物法治理含砷酸性矿山废水的研究进展,包括硫酸盐还原菌和铁氧化菌矿化除砷技术。硫酸盐还原菌矿化除砷技术的研究较多,但由于碳源成本较高、硫酸盐还原菌的砷耐受性较低以及矿化过程对反应器要求高等,难以得到大规模应用。铁氧化菌矿化除砷技术的研究较少,其矿化形成的不同矿物的稳定性存在争议,目前尚处于实验室研究阶段,但铁氧化菌的砷耐受性高,矿化过程对反应器要求低,且能加速酸性矿山废水中As(Ⅲ)的氧化,发展前景可观。Research progress on the biomineralization technologies of sulfate-reducing bacteria(SRB)and iron-oxidizing bacteria(IOB)for removing arsenic from acid mine drainage(AMD)is reviewed.Although there are numerous studies on the removal of arsenic from AMD using SRB,there remain several challenges in the implementation of this remediation technique on a large scale.These challenges include the choosing of carbon sources,the low-level resistance of SRB to arsenic and the high requirement for reactors.Removing arsenic from AMD using IOB is still at the stage of laboratory research given that the stability of different minerals formed during the biomineralization is not very clear.However,this remediation technique has advantages in accelerating the oxidation of As(Ⅲ),the high-level resistance of IOB to arsenic and the low cost for reactors,which has a promising prospect.
