摘要：
Anaerobic co-digestion of waste activated sludge and food waste was investigated semi-continuously using continuously stirred tank reactors. Results showed that the performance of co-digestion system was distinctly influenced by temperature and organic loading rate (OLR) in terms of gas production rate (GPR), methane yield, volatile solids (VS) removal efficiency and the system stability. The highest GPR at 55 degrees C was 1.6 and 1.3 times higher than that at 35 and 45 degrees C with the OLR of 1 g VS L-1 d(-1), and the corresponding average CH4 yields were 0.40, 0.26 and 0.30 L CH4 g(-1) VSadded, respectively. The thermophilic system exhibited the best load bearing capacity at extremely high OLR of 7 g VS L-1 d(-1), while the mesophilic system showed the best process stability at low OLRs (< 5 g VS L-1 d(-1)). Temperature had a more remarkable effect on the richness and diversity of microbial populations than the OLR. (C) 2014 Elsevier Ltd. All rights reserved.
