英文摘要: A major challenge of employing bioelectrochemical system (BES) for reductively degrading recalcitrant contaminants in industrial wastewater is lacking sufficient electron donors. In this work, domestic wastewater (DW) was demonstrated to efficiently drive BES for implementing the decolorization of azo dye, acid orange 7 (AO7). Side benefit was the simultaneous treatment of DW. Decolorization efficiency in BES fed with DW (RDW) was found to be comparable with that either fed with glucose (R-Glu) or acetate (RAC). Much lower reductant usage ratio was observed in R-DW. As a result, when the ratio of electron donors to azo dye decreased to 4.4 mol COD mol(-1) AO(7), DE of R-DW kept over 90% while DEs of R-Ac and R-Glu were significantly dropped due to the insufficient electrons donation. Besides serving as electron donor, DW was proved to also provide some conductivity and buffer capacity. Accordingly, DE of Row was less deteriorated when fully removing the external buffer slats. This study comprehensively revealed the feasibility and superiority of DW as a cost-effective electron donor source in BES and brings this technology closer to the practice. (C) 2016 Elsevier Ltd.
