Biogas can be used in the Northeast
However, in the medium temperature fermentation, the optimal temperature is about 35 degrees Celsius, at 40~45 DEG C, gas production will decline.
Northeast perennial low temperature is a problem.. Because it will affect the temperature of fermentation and gas - metabolic activities and microbial fermentation temperature are closely related, in a certain range, the higher the temperature, the biogas microbial metabolism is more exuberant, more biogas production, namely temperature is beneficial to improve the yield of biogas. Generally, the biogas can be fermented in the temperature range from 8 to 60 DEG C.
From the fermentation cycle, the lower the temperature, the longer the fermentation cycle, the higher the temperature, the shorter the fermentation cycle.The sudden increase or decrease of biogas fermentation temperature has obvious effect on gas production. If the change is too large, the gas production almost stops. For example, if a gas pool is normally produced at a temperature of 35 DEG C, if the temperature drops to a temperature of about 20 DEG C, the gas production is almost completely stopped
