摘　　要：以葡萄糖及豆奶粉为碳氮源,采用不控制温度及pH的方式,在厌氧条件下探究不同m(COD)/m(SO42-)、HRT和进水Fe2+负荷对硫酸盐还原菌处理酸性矿山废水效果的影响。结果表明,在进水pH为3.0左右,水温为26～27℃,进水Fe2+的质量度低于450mg/L,m(COD)/m(SO42-)大于1.5的条件下,SO42-去除效果稳定,平均去除率在80%以上;而m(COD)/m(SO42-)大于2.0时,COD有较好的降解效果,Fe2+平均去除率在90%以上,重金属的平均去除率在99%以上。The present study was conducted to investigate the effect of different hydraulic retention times（HRT）,initial Fe^2＋ concentrations and initial ratios of m（COD）/m（SO4^2-） on treatment of acid mine drainage by sulfate reducing bacteria,using glucose and soy as carbon source and nitrogen source,adopting static test under anaerobic condition,without control of pH and temperature.The experiment results shows that in the condition of initial pH 2-3,water temperature 26-27,initial Fe^2＋ concentration below 450 mg/L,initial ratios of m（COD）/m（SO4^2-） above 1.5,average sulfate and Fe^2＋ removal efficiency were stabilized and were found to be over 80% and 95%.While the ratio was above 2.0,COD had better degradation efficiencies.Removal rate of heavy metal was over 99% averagely.
