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

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.
