Background
In the current biochemical treatment system, biological denitrification is a process of finally converting nitrogen-containing compounds in water into nitrogen gas through ammoniation, nitrification and denitrification so as to be removed. Wherein the ammoniation is carried out under aerobic or anaerobic conditions, the nitrification is carried out under aerobic conditions, and the denitrification is carried out under anoxic conditions. In order to ensure the removal rate of the total nitrogen, a relatively high reflux amount of nitrifying liquid is generally needed, and the nitrifying liquid at the tail end of the aerobic zone is refluxed to the anoxic zone for denitrification.
However, the nitrified liquid carries with it a part of oxygen to enter the anoxic zone, and with the increase of the reflux amount of the nitrified liquid, the oxygen entering the anoxic zone inevitably increases, and finally, excessive oxygen destroys the anoxic environment, and inhibits the denitrification action, thus being not beneficial to removing the total nitrogen.
