Effects of Temperature and Inoculation Ratio on Methanogenic Performance during Anaerobic Digestion of Food Waste
摘要
Abstract
Anaerobic digestion is one of the effective approaches for resource utilization and harmless disposal of food waste,among which temperature and inoculum-to-substrate ratio(ISR)are key process parameters de-termining its treatment performance.Batch anaerobic digestion experiments of food waste were carried out un-der two temperature conditions(54 ℃ and 35 ℃)and two ISR levels(1.4 and 1.0).The results indicated that the optimal process condition was 54 ℃ with an ISR of 1.0,achieving a TS-based biogas yield of 292.15 mL/g and a volatile solids degradation rate of 68.13%,respectively.Volatile fatty acids(VFAs)in all experimental groups were dominated by acetic acid.Nevertheless,temperature and ISR exerted significant im-pacts on the total VFAs concentration.VFAs could be effectively degraded in the thermophilic groups,while the mesophilic group with low inoculum dosage presented a higher risk of acid accumulation.Under thermoph-ilic conditions,the concentration of coenzyme F420 increased significantly,and showed a synergistic effect with the lower inoculum dosage,which effectively enhanced the activity of methanogenic communities and acceler-ated VFAs conversion.关键词
