  • 摘要: 考察了阴极负载Co3O4和MnOOH对天然水体中沉积物微生物燃料电池（SMFC）产电性能和SMFC对沉积物中有机质去除率的影响。实验结果表明，SMFC阴极负载Co3O4和MnOOH后，体系的输出电压由483 mV增大到549 mV和534 mV；相应体系的内阻由206 Ω显著降低到99 Ω和128 Ω，最大功率密度（Pmax）由3.3 mW/m2增大到9.1 mW/m2和6.6 mW/m2。此外，SMFC体系的电流密度与沉积物中烧失量（LOI）、易氧化有机质（ROOM）去除率呈线性关系，并且阴极负载Co3O4和MnOOH可以促进阳极沉积物中有机质的去除。
    Abstract: The effect of Co3O4 and MnOOH modified cathodes on the electricity generation performance of sediment microbial fuel cell (SMFC) and the corresponding organic matter removal efficiency in sediment by SMFCs was investigated. Experimental results suggested that compared with the SMFC with blank cathode, the output voltages of the SMFCs used Co3O4 and MnOOH modified cathodes increased from 483 mV to 549 mV and 534 mV. The corresponding internal resistances decreased from 206 Ω to 99 Ω and 128 Ω, and the maximum output power densities were elevated from 3.3 mW/m2 to 9.1 mW/m2 and 6.6 mW/m2, respectively. Besides, there existed linear relationships between the current densities of the SMFCs and the removal efficiencies of loss on ignition (LOI) and readily oxidizable organic matter (ROOM) in sediments. Furthermore, Co3O4 and MnOOH modified cathodes obviously promoted the removal efficiency of organic matter in sediments.
