Sažetak
The effect of cathode type on contaminant removal efficiency and electricity production in disposing leachate was investigated in a self-assembled microbial fuel cell (MFC). When the landfill leachate was treated with the chemical-cathode MFC (CMFC) and aerobic bio-cathode MFC (ABMFC), the maximum output voltages were 699.0 mV and 459.4 mV, the maximum output powers were 197.7 mW m–3 and 147.6 mW m–3, and the internal resistances were 900 Ω and 700 Ω, respectively. After running the MFCs for 45 days, the COD removal ratios of CMFC and ABMFC were 56.5 % and 64.3 %, the Coulombic efficiencies were 14.3 % and 17.1 %, and the ammonia nitrogen removal ratios were 53.8 % and 58.1 %, respectively.
