Especially for the high concentration of denitrification wastewater in the actual operation process, when using the traditional process, if there is a poor mode of operation or poor control of the operating conditions, it is easy to cause the accumulation of nitrate, and when there is nitrate accumulation, it will greatly affect the efficiency of denitrification and nitrogen removal. However, in adopting a high-efficiency denitrification tower, due to the unique bacterial colony, sludge concentration, operation principle, and denitrification mode, it is resistant to high nitrite concentration to ensure high-efficiency denitrification efficiency.
