摘　　要：用微生物燃料电池处理电镀废水，在产电的同时，还能析出金属单质。实验室采用Cu（NO，），和AgN03代替电镀废水作为阴极电子受体，糖蜜废水为阳极底物，碳纸60为电极材料，考察了0．1mol／LCu（NO3）2和0．05mol／LAgNO3对电池产电性能的影响。结果表明：在667h，Cu（NO3）2作为阴极电子受体，最大输出电压达到105．1mV，最高功率输出密度0．50mW／cm。，而AgNO，作为电子受体在787h时，输出电压达到最大值120．2mV，最高功率输出密度仅为O．41mW／cm。。研究表明，重金属离子可以作为微生物燃料电池的阴极电子受体，微生物燃料电池（MFC）可以直接将有机废水中的化学能直接转化为电能，同时将重金属还原，具有显著的环境效益和经济效益。Microbial fuel cell （MFC） was used to treat electroplating wastewater, besides the production of electricity, the metal simple substance was also precipitated. Cu （ NO3 ）2 and AgNO3 were used instead of electruplating waste water in acathode, molasses waste water in anode, carbon paper 60 as the electrode material, and the effects ofO. 1 mol/L Cu（ NO3 ） 2 and 0.05mol/L AgNO3 on the electrical properties of the battery production were in vestigated in the experiment. The results showed that： in the 667 h, Cu （NO3 ）2 as the cathode electron acceptor, the maximum output voltage was 105. I mV, the maximum power output density was 0.50mW/cm2 , and AgNO3 in the 787h, reaching maximum output voltage of 120.2 mV, the high- est power output density was 0. 41mW/cm2. The study has shown that heavy metal ions can be used as the MFC receptor; MFC can directly transform chemical energy in organic wastewater into electricity, and reduction heavy metal. In addition MFC is significant in environment and economy.
