Abstract

Abstract

The effect of slurry recirculation time(1 h/d, 6 h/d, 12 h/d and 24 h/d) on thermophilic((55±2) ℃) anaerobic digestion of kitchen waste for hydrogen production with high solid content(15%TS) was investigated in this study. The microbial community succession was studied in the condition of different slurry recirculation time. The results indicated that increasing the recirculation time of biogas slurry could improve the hydrogen production and alleviate VFAs accumulation. The maximum hydrogen production was obtained as 111.44 L at the recirculation time of 24 h/d. The concentration of VFAs was 28.34 g/L, 15.40% lower than that in the condition of 1 h/d. Increasing the recirculation time during anaerobic fermentation of kitchen waste could improve the pH of the acidification system, and the ammonia accumulation was not formed. In the experimental group with a shorter recirculation time(12 h/d), microbial community structural diversity decreased during the fermentation. At the phylum level, Firmicutes became the dominant bacteria(with a relative abundance of 49.2% to 89.5%). The experimental group maintained high microbial diversity at the condition of longer recirculation time, with the relative abundance of Firmicutes 27.8%, Chloroflexi 33.6%, Proteobacteria 13.0%, Euryarchaeota 12.3%. At the genus level, the group with longer recirculation time showed higher abundance of hydrogenogens, with the relative abundance of Clostridium 10.5% and Thermoanaerobacterium 3.2%. Extending slurry recirculation time could promote hydrogen production by metabolism of VFAs and glucose, and Proteiniphilum was the key microorganism for VFAs degradation. Redundancy analysis indicated that slurry recirculation time and biogas production were related to Firmicutes and Chloroflexi.
