At 24 h hydraulic retention time and 3 kg chemical oxygen demand (COD) m-3 d-1 volume loading, the tested BES could remove 86.5% of 20100 mg L-1 (COD) and 97.9% of 1330 mg L-1 NH4+-N in raw leachate. The corresponding maximum power density (Pmax) was 2.85 Wm-3 and internal resistance Rint was 47.5£[ in aerating period, and was 2.70 Wm-3 and 52.5£[ in the non-aerating period. Owing to the efficient cathodic denitrification via BES reaction, the removal of total nitrogen can exceed 90%, much higher than those reported in the literature. ? 2015 Taiwan Institute of Chemical Engineers.Ammonium removalCOD removalDenitrificationLandfill leachate[SDGs]SDG6[SDGs]SDG7[SDGs]SDG12journal article10.1016/j.jtice.2015.06.0192-s2.0-84953737725https://www.scopus.com/inward/record.uri?eid=2-s2.0-84953737725&doi=10.1016%2fj.jtice.2015.06.019&partnerID=40&md5=bcce072e8efa978dc4e2630cba06068f
