温度是影响沼气发酵产气的一个重要因素[1]。为了抵御低温对沼气发展的影响,不断探索改进沼气建池模式,提高沼气池发酵温度,促进内蒙古乌兰察布市农村沼气持续发展。分析总结沼气利用过程中出现的问题,不断探索寒冷地区沼气发展模式。通过示范推广得知,日光温室内“四位一体”模式较其他模式具有显著地抗低温能力,产气利用时间长,值得在寒冷地区借鉴推广。
Temperature is an important factor affecting biogas fermentation gas [1]. In order to resist the impact of low temperature on the development of biogas, we will continue to explore ways to improve the biogas construction, increase the fermentation temperature of biogas digesters, and promote the sustainable development of rural biogas in Wulanchabu, Inner Mongolia. Analyze and summarize the problems occurred during the utilization of biogas and continuously explore the development mode of biogas in cold regions. Through demonstration and promotion, solar greenhouse “four in one ” model than other models have significant resistance to low temperature capacity, gas utilization for a long time, it is worth drawing in the cold area promotion.
