Experimental Study on Biogas Production by Mesophilic Fermentation for Rabbit dung

摘要

In order to obtain the biogas fermentation potential of rabbit dung, the anaerobic batch fermentation experiments were performed at 30°C, the feed concentration of 6.09% and an initial pH of 7.0. The experiment was design of the control group (120 mL seeding materials) and the experimental group (120 mL inoculums + 21.51 g rabbit dung) to explore the potential of the anaerobic digestion of rabbit dung. The results show that biogas production of rabbit dung during total fermentation period of 36 days is 3084 mL, TS biogas yield is 432 mL/g, and gas yield is 508 mL/g. The results indicated that rabbit dung can be used for biogas fermentation and the fermentation was good.
