Abstract
The paper considering the condition of the north areas of China we designed the biogas fermentation technology which is applicable in Heilongjiang Province. It include the technology of prehandling of manure, burning biogas to warm up the digester, recycling of effluent and cyclically and mixing of slurry. It solved the problems of how to hold the digester temperature and how to warm up the digester with biogas energy. With feasibility assessment of 300 m3 cattle manure biogas fermentation project which adopt the technology mentioned above, we draw the conclusion that the technology of animal manure handling system is feasible.
