秸秆类原料与粪便按比例混合发酵产沼气试验

Biogas Production Test by Fermentation of Proportional Mix about Straw Materials and Excrements

以秸秆为主要原料发酵产沼气,既能缓解甘肃省秦安县户用沼气池粪便原料短缺的问题,也是解决农村能源问题和秸秆资源综合利用的一种重要途径。为了探索出秸秆类原料与粪便混合进行发酵产沼气的有关规律,项目组在剪湾村开展单因素试验研究,利用归纳总结的方法,综合对比试验数据,掌握秸秆类原料与粪便混合发酵产沼气的最佳比例,为秦安县沼气事业的发展提供科学依据。

Using straw as main raw material for biogas fermentation could relieve problem of raw materials shortage for household biogas of Qin'an county. It is an important way for the comprehensive utilization of straw resources,and could solve rural energy problems. In order to explore regularity of biogas production by fermentation of proportional mix about straw materials and excrements,experimental study on single was done in Jianwan country. Through using method of sum up and comprehensive contrast of test data,best proportion of straw materials and excrements for mixed fermentation to produce biogas was grasped. It provided scientific basis for the development of biogas project in Qin'an county.
