北方低温区规模化沼气生产工艺的研究

Research on Large-scale Biogas Production Technique in North Low Temperature Area

自然条件下的产甲烷生物菌种难以适应我国北方寒冷低温条件,使得沼气生产工艺难以满足连续、高产、高转化率的要求。通过对低温适应菌群的筛选和新型规模化沼气生产工艺及产气装置的研究,旨在实现北方冬季条件下连续、高效的产气。

The Methanogen under natural conditions was difficult to adapt the low temperature of cold north area of china which made the present biogas production technique hardly meet the demand of continuity,high production and high conversion rate.The screening of bacteria to adapt to low temperature and the new large-biogas production technology and gas production equipment were researched in order to achieve continuous and efficient gas in winter of north china.
