With the development of large-scale and intensive pig breeding,the harmless disposal of dead pigs has become increasingly prominent.The method to process dead pigs by biogas engineering can realize resource utilization of dead pigs and and obtain high economic benefit. In this paper,through a batch of experiments,the feasibility of anaerobic co-digestion of dead pigs and pig manure was verified,and effects of addition proportion of dead pigs and reaction temperature on biogas production from the anaerobic co-digestion were analyzed. The results showed that when the reaction temperature was 35 ℃ and the adding proportion of the dead pig was 12%,the fermentation could get the best effect,and the maximum of methane content could reach 64. 72%,while the total biogas yield was up to 5 310 ml,which was 26% higher than single fermentation of pig manure. Meanwhile,the unit TS and VS biogas yield could rise by 30% and 22% respectively.
