The invention discloses a method for producing methane by anaerobic fermentation of corn stover. Mix and evenly add nitrogen fertilizer into the fermenter according to the weight ratio, keep the temperature below 0°C, then warm up to room temperature and stir, then add livestock and poultry manure into the fermenter, seal it for anaerobic fermentation, and the fermentation temperature is 35～ 55℃, the fermentation period is 60 days. During the anaerobic fermentation process of the present invention, the pH value of the fermentation system is maintained at 6.5-7.8, the methane gas production is less affected by the pH value and the fermentation temperature, and the methane gas production is relatively high. |
