Improvement in the performance of streptomycin wastewater MFC treatment and electricity generation by co-substrate addition

摘要: 以K3[Fe（CN）6]和NaCl混合溶液为阴极液，以驯化的人工湖泊底泥为微生物菌种，以链霉素废水为阳极液，构建微生物燃料电池实验系统，研究添加共基质前后微生物燃料电池的废水处理效果与同步发电性能。结果表明，以链霉素废水为阳极液的微生物燃料电池的产电能力及废水处理效果均较差，并且随着链霉素浓度的增大而进一步恶化；但将葡萄糖作为共基质添加至阳极链霉素废水后，微生物燃料电池的产电能力和废水处理效果均显著提高。链霉素浓度为50 mg/L时，未添加共基质的微生物燃料电池处理链霉素废水的COD去除率为52%，产电电流密度为25 mA/m2，输出电压为4.72 mV；添加共基质后，COD去除率为92%，稳态产电电流密度为300 mA/m2，稳态输出电压为54 mV。Abstract: A microbial fuel cell system was built by using the mixed solution of K3[Fe (CN)6] and NaCl as catholyte, acclimated sediment of an artificial lake as the source of microbial species, and streptomycin wastewater as anolyte; the effect of co-substrate addition on the purification effect and electricity generation ability of the microbial fuel cell was investigated. The results show that the electricity generation ability and wastewater treatment effect of microbial fuel cell with streptomycin wastewater as anolyte are quite poor and deteriorate even further with the increase of the streptomycin concentration. However, the electricity generation ability and wastewater treatment effect of the microbial fuel cell can be significantly improved by adding glucose as a co-substrate to the anode streptomycin wastewater. In case without the co-substrate, the COD removal rate is only 52% when the concentration of streptomycin is 50 mg/L, with a steady electric current density of 25 mA/m2 and a steady output voltage of 4.72 mV; by adding the co-substrate, the COD removal rate reaches 92%, with a steady electric current density of 300 mA/m2 and a steady output voltage of 54 mV.
