[0002] Short - cut nitrification, also known as nitrosation, is the first step of the nitrification process. It only oxidizes ammonia nitrogen to nitrite nitrogen during the nitrification stage, causing the accumulation of nitrite nitrogen. Then, processes such as denitrification or anaerobic ammonium oxidation can be connected to achieve the nitrogen removal effect. During the short - cut nitrification stage, the dissolved oxygen concentration is usually controlled at 0.3 - 1.0 mg / L. At a lower dissolved oxygen concentration, the activity of nitrite - oxidizing bacteria is inhibited, making ammonia - oxidizing bacteria the dominant population in the nitrifying flora, thus achieving the accumulation of nitrite nitrogen. The operation condition of low DO reduces the aeration energy consumption of the biological nitrogen removal system by 50 - 60%.

[0003] However, during the existing short - cut nitrification reaction process, since the liquid stored inside is prone to be corrosive or toxic during the treatment process, it is easy to cause corrosion inside the reaction device, resulting in a problem of reduced use effect.
