Embodiment Construction
[0029] The reactors used in this method are all SBR, made of plexiglass, with an effective volume of 10L. Aeration devices are installed at the bottom of some short-path nitrification reactors, which can control constant dissolved oxygen by adjusting flow meters and DO online feedback. Part of the short-path nitrification SBR reactor and the anammox SBR reactor are equipped with agitators to ensure uniform mixing of mud and water. The water is fed by the peristaltic pump, and the water is discharged by the electric drain valve. The time of water in and out is controlled by the online platform.
