The temperature plays a key factor in biogas anaerobic reaction,especially in winter. In order toimprove the anaerobic reaction temperature and increase the rate of gas producing,we combine a new type of solargreenhouse with biogas anaerobic reaction in the experimental research. This thesis firstly analyzes the new solargreenhouse design and material selection,and then monitors the anaerobic reactor at ambient temperature andunder the new solar greenhouse in a multipoint way. At last,we finish the data col...
