Abstract

A membraneless, 3.5-L bioelectrochemical reactor with biocathode and anoxic/oxic zones was established for treatment of raw landfill leachate. 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 (P_max) was 2.85 Wm^-3 and internal resistance R_int was 47.5Ω in aerating period, and was 2.70 Wm^-3 and 52.5Ω 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.
