【摘要】 分析了北方地区冬季沼气池产气量偏低的原因和沼气池池温与气温的变化关系,根据生物质(农作物秸秆)发酵升温的原理,利用麦秸发酵产热对提高沼气池池温进行了的试验。结果表明:生物质发酵升温能提高沼气池池温和产气量,解决沼气池在冬季不能正常使用的问题。文章对在沼气池拱顶上部改建生物质发酵升温池的技术工艺进行了介绍。更多还原

【Abstract】 Analysing on the reason of the low temperature in methane pool in north areas in winter,and the relations of temperature change between the methane pool and the atmospheric temperature;According to the principle of the biolysis and fermantion make heat,making intial research that fermentation from wheat straw makes heat and elevates the methane pool temperature and the output of the methane,and solving the problem that poeple normally use the methane as life fuel in winter;and having the research about technique design on the top of the methane pool in order to elevate the temperature.更多还原
