The effects of pH, chemical oxygen demand (COD) concentration and external resistance on denitrifying microbial fuel cell were evaluated in terms of electricity generation characteristics and pollutant removal performance. The results showed that anodic influent with weakly alkaline or neutral pH and cathodic influent with weakly acidic pH favored pollutant removal and electricity generation. The suitable influent pH of the anode and cathode were found to be 7.5–8.0 and 6.0–6.5, respectively. In the presence of sufficient nitrate in the cathode, higher influent COD concentration led to more electricity generation and greater pollutant removal rates. With an anodic influent pH of 8.0 and a cathodic influent pH of 6.0, an influent COD concentration of 400 mg/L was deemed to be appropriate. Low external resistance favored nitrate and COD removal. The results suggest that operation of denitrifying microbial fuel cell at a lower external resistance would be desirable for pollutant removal but not electricity generation.

Microbial fuel cell (MFC) represents a new method for simultaneously swine wastewater treatment and electricity generation. However, few studies revealed the high electricity generation and pollutant removal using a large-scale single-chambered MFC in treating swine wastewater. Results indicated optimal hydraulic retention time (HRT) of swine wastewater was 8 d considering the removal efficiency and the power density. Under this condition, this MFC system removed 85.62% TCOD and 73.6% NH3 as well as achieved power density of 368 mW/m2. Results also showed the maximum power density of the MFC was 382.5±10.6 mW/m2 MFC at 350 Ω. TCOD concentration in the swine wastewater was limiting factor for power output. The maximum power density was Pmax= 385 mW/m2, with a half-saturation concentration of Ks=2,050 mg/l. To our knowledge, this is the first time to demonstrate the electricity characteristics of a large-scale single-chambered MFC in treating swine wastewater.
