Abstract | This study constructed a single-chamber Cloth Cathode Assembly-Microbial Fuel Cell(CCA-MFC) for treating swine wastewater under a fed-batch mode. The MFC performance of power generation and wastewater treatment was evaluated by measuring the voltage output, removal efficiencies of chemical oxygen demand(COD) and ammonia-nitrogen(NH4+-N). The effects of anodic pH on the MFC performance were studied as well. Results showed that the anodic pH of 10 was the optimum condition for MFC operation. Under the optimum condition, the MFC approached the highest power density 2.10 W/m3, COD removal rate 86.7% and NH4+-N removal rate 92.8%. Compared to MFCs with the anodic pH of 6 and 8, the maximum power density of the MFC with the anodic pH of 10 was increased by 2.7 times and 1.9 times. Besides, the removal rate of COD was enhanced by 13.8% and 6.7%, and NH4+-N was enhanced by 5.3% and 3.5%, respectively. The results suggested that anodic pH of 10 was the optimum condition for MFC operation as an approach to simultaneous power generation and swine wastewater treatment. |
