Paper Title:
Study on Anaerobic Digestion Performance of Kitchen Wastes: Inhibition of Ammonia Nitrogen and Volatile Acid on the Anaerobic methanogenesis
  Abstract

The inhibition of ammonia nitrogen and volatile acid on anaerobic methanogenesis during the anaerobic digestion of kitchen wastes by way of digest fluid backflow was studied. The experiment was conducted at 35°C, and used kitchen wastes as organic carbon source .The results shows that the ammonia nitrogen inhibition concentration is 1400-1700 mg/L. When the ammonia nitrogen concentration rises to 2000 mg/L, the anaerobic methanogenesis efficiency decreased obviously, along with the accumulation of volatile acid. At the feeding organic load of 3.5-4.0kgVS/(m3.d), the anaerobic methanogenesis system was stable operation, the higher VS reduction (72.17%) and the higher methane production rate were obtained..
