Abstract

This paper studies on the biogas production yield of which use the lily straw as raw material and the fermentation is batch by batch at 30°C. In the third day of fermentation, fermented liquid became acidic. But it can be back to normal with the action of the anaerobic microbe. Its biogas yield is higher than the other group to adjust pH value. So gas production potential of the lily straw is 475ml/gTS and 573ml/gVS with 31 days of anaerobic digestion. The volumetric biogas production rate reaches 0.19ml/ml/d.
