    摘要
  • 摘要: 针对食堂餐饮废水,建立微生物燃料电池实验系统,研究微生物燃料电池废水处理与同步发电性能。首先使用Fe(NO3)3溶液作为阴极电解液进行实验,证明餐饮废水生物降解及产电的可行性;分别采用NaCl溶液和K3[FE(CN)6]溶液作为阴极电解液进行对比实验,研究不同运行环境下微生物燃料电池的发电性能和污水净化效果。结果表明,采用NaCl溶液和K3[FE(CN)6]溶液作为阴极电解液时的COD去除率分别是30%和22%左右,平均电流密度分别为5.6和5.2 mA/m2。在污水稀释比为2:1、NaCl电解液浓度为0.4 mol/L的情况下,微生物燃料电池系统的发电性能和净水效果达到最佳状态,稳态电流密度为8.8 mA/m2, COD去除率为33.3%。
    Abstract: For treatment of restaurant wastewater, an experimental system of microbial fuel cell was set up, and the power generation and wastewater purification performance of microbial fuel cell system were studied. Firstly, Fe(NO3)3 solution was used as the catholyte to prove the feasibility of wastewater biodegradation and simultaneous electricity generation from restaurant wastewater. Then, NaCl solution and K3[FE(CN)6] solution are respectively used as the catholyte to conduct contrastive experiments, for studying the effect of power generation performance and wastewater purification of microbial fuel cell system in different operating environment. The results showed that the COD removal efficiency of NaCl solution and K3[FE(CN)6] solution were 30% and 22% respectively, whose average current density were 5.6 mA/m2 and 5.2 mA/m2. In the case that the wastewater dilution ratio was 2:1 and the concentration of NaCl solution was 0.4 mol/L, the generating ability and the purifying effect of the microbial fuel cell achieved the best state, whose steady current density reached at 8.8 mA/m2 and the COD removal efficiency was 33.3%.
