The research takes low C/N ratio sewage as the research object, and quickly realizes the accumulation of nitrite nitrogen by adding inhibitors into the SBBR reactor, and realizes the nitrogen removal by anaerobic ammonia oxidation in the reactor. Determining the optimal operating parameters is of farreaching significance for the treatment of wastewater with high ammonia nitrogen and low C/N and achieving economical and efficient nitrogen removal. Control the ammonia oxidation reaction, keep the nitrification process in the nitrosation stage, and realize the rapid accumulation of NO2--N is the problem that the reactor needs to solve. This experiment uses a combination of batch test and periodic test to conduct experimental research on various influencing factors in the partial nitrosation process: temperature, pH, DO and find the best operating conditions to achieve high-efficiency accumulation of NO2--N and optimize the reaction conditions.
