北方冬季沼气池的增温技术探讨

Research on Methane Pool Temperature Improving Technique in North China in Winter

通过分析北方地区冬季沼气池产气量偏低的原因和沼气池池温与地温的变化关系,根据生物质(农作物秸秆)发酵细菌的作用产生热量升温的原理,利用麦秸秆发酵产热对提高沼气池的池温进行了初步的试验探讨,能提高沼气池池温和产气量;通过沼气塑料大棚试验,发现沼气塑料大棚能提高冬季池温,解决北方冬季用户因气温低沼气不足问题,达到满足用户正常生活用沼气燃料。

By analyzing the reason of the low temperature in methane pool in northern areas in winter and the relationship between the change of methane pool temperature and atmospheric temperature, tiffs study aimed to research in improving the methane pool temperature by the heat from wheat straw fermentation according to the theory of biolysis and fermentation making heat,and elevate the methane pool temperatttre and the output of the methane; through the plastic roof test,this study concluded that the methane pool temperature could be elevated by using plastic roof in order to solve the methanol shortage problem caused by low temperature and ensure the normal production of methanol.
