The biomass energy is the fourth largest energy with the total energy consumption lower than that of coal, petroleum and natural gas at present, has the characteristics of wide distribution, low cost, cyclic regeneration and the like, and is an ideal novel energy material. The anaerobic digestion technology is a common means for converting and utilizing biomass energy, and polysaccharides, proteins and fats in the biomass can be converted into methane gas which is clean energy. However, in the anaerobic digestion process, nitrogen-rich substances such as protein and polypeptide can cause the accumulation of ammonia nitrogen, and when the content of ammonia nitrogen is too high, the activity of methanogenic bacteria can be inhibited, so that the methanogenic efficiency is low. Free ammonia nitrogen has greater toxicity to methanogenic flora, and temperature is a factor that affects the concentration of free ammonia nitrogen.

The domestication period of the biological domestication is long, and the labor cost is high; the mixed digestion has requirements on the mechanism mixing proportion, and the operation is more complex; the addition of inorganic materials may cause side effects to the inside of the reactor.
