固体物浓度温度对农业废弃物厌氧发酵影响研究

Effect of Solid Concentration and Temperature on Anaerobic Fermentation of Agricultural Waste

研究了厌氧沼气对不同固体浓度、牛粪及秸秆温度发酵的影响。结果表明,TS=8%~14%范围内,固体浓度越高,牛粪和牛粪加稻草的产气量越大,不同固体浓度下牛粪和牛粪加稻草的产气量越大。牛粪和秸秆沼气厌氧发酵的最适温度分别为25℃、40℃和35℃。

The effects of anaerobic biogas on the fermentation of different solid concentrations,cow dung and straw were studied.The results showed that TS=8%~14%,the higher the solid concentration,the greater the gas production of cow dung and cow dung plus rice straw,and the greater the gas production of cow dung and cow dung plus rice straw under different solid concentrations.The optimum temperature for anaerobic fermentation of cow dung and straw biogas was 25℃.40℃ and 35℃ respectively.
