Low-carbon and high-efficiency amino acid wastewater treatment process

The invention relates to a low-carbon and high-efficiency amino acid wastewater treatment process. The treatment process comprises the following steps: discharging amino acid wastewater into a comprehensive wastewater regulating tank for regulation; then the wastewater is lifted to an IC reactor, anaerobic reaction effluent enters an aerobic tank to deeply remove COD (Chemical Oxygen Demand), and the nitration process of half of NH4 < + >-N is controlled in the step of NO2 -N by inoculating nitration sludge; reacting the other half of NH4 < + >-N with NO2 -N through an anaerobic ammonia oxidation strain to generate N2 and NO3 -N; effluent of the anaerobic ammonia oxidation reactor enters a synergistic short-cut denitrification reactor, heterotrophic short-cut denitrifying bacteria and sulfur autotrophic short-cut denitrifying bacteria are jointly and synergistically used, NO3 -N is denitrified and controlled to be NO2 -N, and the effluent flows back to the anaerobic ammonia oxidation reactor, s
