添加酒糟、草木灰对猪粪厌氧发酵的影响
The influences of adding lees and plant ash on anaerobic fermentation of pig manure
摘要
Abstract
Take the pig manure as fermentation materials,the effect of, by adding varying amounts of lees and plant ash on the anaerobic fermentation biogas production at 25 ℃, the aerogenesis rate、 accumulated gas production, pH, NH3-N content and CH4 content in the anaerobic fermentation process was analyzed. The results show that the accumulated gas production get the highest as well as the CH4 content when adding lg plant ash;the same as adding 5 g lees into the pig manure. Adding 1,3 g and 5 g lees in the anaerobic fermentation process respectively, the tendency of pH , present drop-increase-drop, and NH3-N increase-drop-increase. But Adding 1, 3 g and 5 g plant ash respectively in the anaerobic fermentation process, the tendency of pH and the NH3-N are similar, increases at first then reduces and finally becomes stable. In a conclusion, reasonable lees and plant ash addition is the premise to improve the amount of gas production and CH4 content in the pig manure anaerobic fermentation process.关键词
