The gas production effect of two kinds of straws mixed with pig manure via anaerobic fermentation under two sets of temperatures 32°C and 52°C has been studied in this experiment. In the process, sunflower and corn straw were used as raw materials with activated sludge as inoculum in a batch anaerobic fermentation reactor. The results showed that the average methane content of sunflower straw reached 62.55% at 37°C, which was 20.41% higher than that of sunflower straw at 52°C.The cumulative methanogenic yield of corn stalks was higher than that of sunflower stalks at different temperatures. The cumulative methane production of corn stalks was the highest at 52°C, and 67.99 L of methane was produced in 54 days. The cumulative methane production of sunflower stalks was the lowest at 52 °C, and the methane production was 34.09 L in 53 days. The results showed that corn stalks produce more methane than sunflower stalks and are more suitable for high temperature anaerobic fermentation. On the other hand, sunflower stalks were found suitable for medium temperature fermentation. [ABSTRACT FROM AUTHOR] |
