- Abstract:
- Anaerobic digestion is an important technology for harmless and resource treatment of food waste, and temperature is an important affecting parameter. The fermentation technology at mesophilic and thermophilic temperature (43-45 ℃) adopted in the anaerobic section of Xi’an food waste biogas project (phase Ⅰ) is introduced, and the stable operation data of the project are analyzed and summarized. The results show that by using the anaerobic digestion technology at mesophilic and thermophilic temperature, the organic load rate is high, the gas production rate of volatile solid (VS) of waste is 1 170 m3/tVS, and the volume gas production rate of full mixed CSTR fermentation unit is more than 3.0 m3/(m3·d), so that good operation results are achieved.
