英文摘要	Recently, bioelectrochemical systems (BESs) were investigated for enhancing recalcitrant contamination reduction of recalcitrant contaminants. However, comprehensive evaluation of key operational parameters considering both performance and energy conservation were rarely concerned. In this study, impact of the initial concentration, applied voltage and co-substrates types were thoroughly investigated and evaluated for optimization of Alizarin Yellow R (AYR) decolorization. Increase of the initial AYR concentration would decrease decolorization efficiency (DE) and rate (k), while change of applied voltage showed the contrary trend. However, the low unit energy consumption (UEC) demanded the high initial concentration (1194 J.g(-1) for 200 mg.L-1) and the low applied voltage (112.4 J.g(-1) for 0.1 V). kAYR and kPPD fed with glucose were almost twice than acetate, while, UEC was close or lower (the initial AYR under 100 mg.L-1 or applied voltage under 0.3 V), which indicated the superior property of glucose as co-substrate than acetate. The modeling proposed the optimized initial AYR concentration, applied voltage to guarantee the highest decolorization rate and the lowest energy consumption. The study proposed the experimental basis and technique approach to guide the operational parameter for scale-up BES application.
