| 本实验通过研究电池的启动过程、阳极有机物降解率和阴极Cu2+的去除率,评价了微生物燃料电池(microbial fuel cell, MFC)的产电和处理废水性能.以模拟糖蜜废水作为阳极基质,模拟电镀废水作阴极电子受体,建立简单的双室微生物燃料电池.结果表明在外电阻为800 Ω的情况下,电池得到最大电压417.00 mV,从极化曲线上获得最大输出功率密度44.17 mW·m-2,内阻为293 Ω.电池在第五周期时,COD去除率也达到最高47.31%.在第四周期内,Cu2+最大的去除率为59.76%.综上所述,MFC在处理有机废水和电镀废水方面具有可行性. |
| 英文摘要 |
| The start-up procedures, the degradation efficiency of organics at the anode and the removal efficiency of Cu2+ at the cathode of the cell were studied, based on which the performance of MFC (microbial fuel cell) in electricity generation and wastewater treatment was evaluated. A simple two-chamber microbial fuel cell was established with simulated molasses wastewater as substrate at the anode and simulated electroplating wastewater as an electron acceptor at the cathode. The results from a batch of experiments showed that the highest voltage output of 417.00 mV was obtained at an external resistance of 800 Ω,and that the maximum power density of 44.17 mW·m-2was obtained with an internal resistance of 293 Ω based on the polarization curve. In addition, COD removal rate reached its highest value (47.31%) in the fifth cycle, and the maximum removal rate (59.76%) for Cu2+ was recorded in the fourth cycle. In summary, the application of MFC in the treatment of organic wastewater and electroplating wastewater is feasible. |
