Odorous compounds produced from blackwater commonly cause domestic nuisance complaints. In this study, a series of experiments was conducted to apply an electrolytic oxidation system to abate the odor problems from blackwater. The electrolytic process removes odorous compounds from the liquid sources using direct and indirect oxidation; therefore, the system performance mainly relies on electrode materials. Four different electrode materials, SS304, SS316, Ti, Ti/IrO2, were applied, and the electrolytic oxidation showed that hydrogen sulfide and organic constituents were effectively removed. However, the weights of electrodes, SS304 and SS316, were decreased by 7.5~8% due to the electrochemical decomposition from the anode surface. In order to improve the durability and economical feasibility, SS304 was used as the cathode while Ti/IrO2 was used as the anode. The electrode combination with the different materials (Ti/IrO2 : SS304) showed the same odor removal efficiency as that using the same material (Ti/IrO2 : Ti/IrO2). Consequentially, the electrolytic reaction to oxidize odorous and organic constituents in humane manure was strongly affected by the electrode materials, and its combination needs to be carefully selected to achieve better performance.
