摘　　要：以乳酸钠作为进水碳源,以陶粒作为上向流式厌氧生物膜填充床中的填料,研究了利用硫酸盐还原菌处理模拟矿井废水的载体前处理方式、低进水p H值以及温度对硫酸盐还原菌处理重金属效果的影响。结果表明:在酸性前处理方式下,固定化硫酸盐还原菌处理重金属的效率要高于其他两种前处理方式处理重金属的效率,而且其对外界环境变化的抗冲击能力也要优于其他两种处理方式。Using the sodium lactate as carbon source and ceramics as media of up-flow anaerobic packed bed reactor, the influences of pretreatment of carrier, low pH value and temperature on the effect of heavy metal treatment by sulfate-reducing bacteria were analyzed. Results show that the acid pretreatment method treatment efficiency of heavy metals is higher than other two kinds of pretreatment process efficiency of heavy metals by immobilized sulfate-reducing bacteria and the changes in the external environment imoact resistant abilitv is suoerlor to other two processes.
