Abstract

Abstract

With the implementation of waste sorting policy in China, efficient utilization of organic waste becomes a great challenge in China. In this paper, continuous experiments on anaerobic digestions of kitchen waste, fruit and vegetable waste and garden waste were conducted, while ultrasound and alkali-thermal pretreatment were applied to enhance methane production, with the mono-digestion of food waste served as the control. According to different OLRs, the reaction period was divided into low OLR phase[OLR=1, 2 g/(L·d)] and high OLR phase[OLR=4, 6 g/(L·d)]. The results showed that under low OLR, all reaction systems showed strong stability, among which, kitchen waste had the highest VS removal rate of 90.3% and methane yield of 460 mL/g. Besides, after ultrasonic pretreatment and alkali-thermal pretreatment, the methane yields of co-substrates were increased by 7%~8% and 3%~7%, respectively. Under high organic load, the stability of mono-digestion system was significantly reduced, specifically, the pH value was decreased to 6.70 and the concentration of VFA and TAN was accumulated to 1230, 1519 mg/L, while the VS removal rate and methane yield were reduced by 2.8% and 11% as well. However, the co-digestion systems showed stronger resistance to high OLRs. Compared with kitchen waste, the methane yield of co-substrate was increased to 420 mL/g. After ultrasonic pretreatment, the methane yield was further increased by 3%, while the methane yield after alkali-thermal pretreatment was decreased by 4%.
