摘　　要：构建以厌氧活性污泥为阳极区底物、不锈钢网和活性炭颗粒组合三维阳极、硫酸根为电子受体、吸附固定在活性炭纤维柱上的硫酸盐还原菌为生物阴极的微生物燃料电池系统(MFC),在HRT=24h下处理模拟酸性矿井水(实测Hg2+质量浓度为19mg/L,Cr6+为26.3mg/L,Mn2+为40.2mg/L,Ni 2+为44.8mg/L;pH=3.03;COD=114.8mg/L;SO2-4=3 096.1mg/L),系统运行25d.结果表明:SRB生物阴极MFC系统具有很好产电性能,输出电压高达445 mV(外电阻为1 000Ω),表观内阻为200Ω,功率密度最高达75.66mW·m-2;其对AMD pH值的调节效果显著,出水稳定在pH=7.2左右;废水中Hg2+、Cr6+的去除率均为100%,Mn2+去除率为65%以上,最高达94%,Ni 2+的去除率在92%以上;出水COD均在50mg/L左右;SO2-4去除速率最高达1.824kg/m3·d-1.SRB生物阴极MFC对AMD具有良好的调节和处理效果.Construction of anaerobic sludge as an anode substrate area,a stainless steel mesh and activated carbon particles combined anode,sulfate as eletron acceptor,fixed activated carbon fiber adsorption col-unm SRB biological cathode microbial fuel cell system（MFC）,in the HRT=24 h treatment of simulated acid mine drainage （measured concentrations of Hg2 ＋ for 1 9 mg/L,Cr6 ＋ for 26.3 mg/L,Mn2 ＋ for 40.2 mg/L and Ni2 ＋ 44.8 mg/L,pH=3.03;COD=1 14.8 mg/L;SO 2 -4 =3 096.1 mg/L）,system runs 25 d. Research results show that SRB cathode MFC system has a very good electrical properties,the output voltage of 445 mV （1 000 Ω resistance to outside）,the apparent resistance of 200 Ω,power density up to 75.66 mW.m-2 ;Its pH adjustment effect on AMD,efflunt stable at around pH =7.2;Waste water of Hg2 ＋ and Cr6 ＋ removal rate stable at 100%,removal rate of Mn2 ＋ is over 65%,the removal rate is up to 94%,Ni2 ＋ is over 92%;COD in effluent around 50 mg/L;The removal rate of SO 2 -4 is up to 1.824 kg/m3 .d-1 .Shows that the SRB biological cathode MFC to AMD has good adjustment and treat-ment effect.
