Abstract:

Abstract: In order to improve the rural household biogas production with different fermenting materials, prompt the rural household biogas extending, three treats including nitrogen rich materials, carbon rich material and control check material, were designed to analyze individual biogas production, some physical-chemical characteristics of biogas digester and effect factors. All the fermenting materials could meet the household requirement. Biogas production with the nitrogen rich materials has faster rate and slower duration than that with carbon rich material, and the latter production was very lower than the former significantly. The change of temperature is the first factor which affect the biogas production.
