英文摘要	Household thermostatic biogas production system heated by solar energy solves the problem of low gas production in the traditional biogas digesters in winter. However, there is no discussion about the continuous high efficiency of the batches of the batch fermentation in winter. The over-ground household energy thermostat biogas production system heated by solar energy was built in Zhangma village, Minqin county, Gansu province. The gas production performance of semi-continuous fermentation was studied under the actual operating conditions in winter. Under the meteorological conditions of Minqin, the semi-continuous fed-batch anaerobic fermentation experiment results show that the solar thermostatic biogas production system can continuously and stably run in winter, and can maintain high daily gas production for a long time, the average daily biogas production was 0.95 m3 and the cumulative gas production was 110.71 m3 during the whole experimental period. When the minimum temperature is -18.2, the system can still achieve constant temperature anaerobic fermentation in the range of (27±2); Achieving the semi-continuous fed-batch in the batch anaerobic fermentation process can maintain the stable methane content for a long time, the cumulative production of methane is 60.6 m3 and the average methane content is 54.74% during the 116 day testing period. The system can regulate the fermentation temperature to meet the gas demand of a family of 4-5 people in different periods during a year. © 2019, Editorial Board of Acta Energiae Solaris Sinica.
