Bio-cathode microbial fuel cells ( MFCs) were built to treat the aging landfill leachate;the effect of electrode surface area on the aging landfill leachate treatment and electrical performance of MFCs was investigated. The results show that for three sets of bio-cathode MFCs with the ratios of anode area to cathode area being 1:2, 2:2 and 2:1, the stable maximum output voltages are 408, 452 and 396 mV, respectively, with the maximum electric power density of 145. 73, 237. 65 and 136. 50 mW/m3 , the resistance of 350, 200 and 400Ω, and COD removal rate of 21. 18%, 20. 20% and 22. 31%, respectively. After running for 30 days, the concentration of ammonia, nitrate and nitrite nitrogen in landfill leachate is decreased; the ammonia removal rates for the three sets of MFCs are 80. 88%, 73. 61% and 66. 17%, respectively, which is related to the electricity generation of MFCs.
