The temperature is low in northern frigid area of our country,especially in winter. The temperature is the key factor that seriously affecting the activity of anaerobic fermentation microorganisms and restricting the biogas fermentation, and it is also the key issue that restricting the development and construction of the large-scale biogas project in frigid area. In order to solve this problem,a new idea is proposed in the paper,which heating for anaerobic fermentation system by the utilization of solar energy and biomass boiler,and takes the large-scale biogas project as the object of research in Fenglin village,Yi Long town,Yi'an County. The data of heating system under normal operation conditions of reactor can be monitored and acquired at any time by using the Force Control Configuration Software. Through the analysis of operation data of local coldest month( January),the results show that the system under normal conditions can ensure the conventional gas production of large-scale biogas reactor in winter,which has an important guiding significance to the development of large-scale biogas project in northern frigid area.
