The biogas amounts with stable flowing rate require heating in cold weather. This study focuses on using solar energy for heating biogas digester. In this research we used energy plus building energy simulation software and real weather data for simulation the heating of biogas digester with 8760 hours simulation .The research was carried out in two parts: The first one is one biogas digester above ground without heating. The Second part of this study is a simulation of one biogas digester with solar heating by using a new design based on double plastic cover. It has shown that the use of solar energy can achieve the optimum temperature for biogas production process almost the year time. Using double plastic cover is the most suitable method with economic form for heating biogas digester above ground.

In order to get the biogas fermentation potential of the Hylocereus undatus stem, this experiment was conducted the CSRT anaerobic batch fermentation with the fresh hylocereus undatus stem as the raw material and blue green algae slurry as inoculum, on the condition of feed concentration of 6.25%, temperature of 30°C and pH of 8.0. The fermentation period lasted 70 days. The results showed it produced total 4800mL biogas while went over the 90% of the biogas production in the former 48 days. The TS biogas production rate was 695mL/g, the VS biogas production rate was 80mL/g, and the raw material biogas production rate was 70mL/g. It implicated that Hylocereus undatus stem is a kind of good biogas fermentation raw material.

It presents a new idea of producing methane with solar heating. In order to improve the temperature and promote production of methane, providing the run situation of solar digesters on every stage with the heat-transfer content and the temperature of digesters is shown in this article. It indicates that in this experimental study, according to processing and analysis the experimental data, it’s beneficial to improve the rates of biogas production, and it solve the problem of digester and safe operation in winter in the northeast of China.

In order to get the biogas fermentation potential of the Cynodon dactylon (L.)Pers, this experiment was conducted the CSRT anaerobic batch fermentation with the Cynodon dacytlon (L.)Pers. as the raw material and the mixed cultivate as inoculum, on the condition of feed concentration of 6.20%, temperature of 30°C and pH of 7.5. The fermentation period lasted 42 days. The results showed it produced total 4400mL biogas while went over the 80% of the biogas production in the early 25 days. The TS biogas production rate was 311mL/g, the VS biogas production rate was 372mL/g, and the raw material biogas production rate was 288mL/g, which implicated that Cynodon dactylon (L.)Pers. is a potential biogas fermentation raw material.
