Abstract This paper investigated the hypothesis that enhancing anaerobic digestion of kitchen wastes by accelerating DIET through incorporating granular activated carbon (GAC).Besides,changes of microbial communities by the incorporation of GAC were also studied.The experimental results showed that,GAC reactors could operate stably with high methane production rate under the organic loading rate (OLR) as high as 10.4kgCOD/(m³·d).In contrast,for the control reactors without GAC incorporation,the methane production rate and pH declined sharply when the OLR increased to only 7.8kgCOD/(m³·d).In addition,the volatile fatty acids severely accumulated and resulted in the treatment efficiency of control reactors deteriorated.Microbial community analysis showed that bacteria capable of extracellular electron transfer (34% of bacterial community) and methanogens known to participate in DIET (88% of archaeal community) were significantly enriched on the GAC surface.It demonstrated that the addition of GAC could enrich these two groups of microbes and enhance the anaerobic digestion of kitchen waste through DIET.
