英文摘要Little is known about the effect of carbon-based conductive material (CM) addition on the anaerobic co-digestion of fat, oil and grease (FOG) and waste activated sludge (WAS). In this study, three types of carbon-based CMs (nano-graphite (NG), granular activated carbon (GAC), and carbon cloth (CC)) and nine dosages were evaluated for their influences on co-digestion performance. The best dosage was achieved at 0.2 g/L NG, 10 g/L GAC, and 1 cm ? 5 cm CC with 13?22% incremental methane production, 25?55% increased VS removal and 28?32% enhanced COD conversion efficiency compared to the control. The highest total amount of bacteria/archaea was found in CC (1 cm ? 5 cm), followed by GAC at 10 g/L and NG at 0.2 g/L, which were all higher than those of the control. Microbial community analysis revealed that direct interspecies electron transfer (DIET)-mediated syntrophic acetate oxidation (SAO) enabling faster acetate conversion might be responsible for the enhancement of methane production.
