摘　　要：为研究可渗透反应床固定化硫酸盐还原菌对酸性矿井水中多种重金属离子的原位修复效果,利用厌氧反应器模拟可渗透反应床,考察了硫酸盐还原菌对重金属的耐受性,及驯化后的硫酸盐还原菌对实验室模拟酸性矿井水中重金属离子的处理效果.结果表明,驯化后的硫酸盐还原菌混合菌群可有效去除酸性矿井水中多种重金属离子,其中Cu2+、Pb2+、Zn2+去除率均可达到90.4%以上,Cd2+的去除率也能达到75.67%以上.For resraching the effect of porous reaction bed fixed sulfate-reducing bacteria in situ remedia- tion of heavy-metal in acid mine water,in the anaerobic reactor, the suitable medium of sulfate reducing bacteria and their tolerance to heavy metals were studied. Moreover, the treatment of laboratory simula- tion heavy metal wastewater by the domestication of sulfate reducing bacteria was investigated. The re- sults show that the domestication of sulfate reducing bacteria mixed flora is effective for removalling wastewater containing Cu2＋ , Pb2＋ , Zn2＋ , Cd2＋. The removal rate of Cu2＋ , Pb2＋ , Zn2＋ can reach above 98%,and the removal rate of Cd2＋ also can reach above 78%.
