At present, in the conventional A O sewage biochemical treatment process, three pool body areas with different characteristics and functions of anaerobic property, anoxic property and aerobic property are always arranged. Wherein the anaerobic zone is a non-aerobic zone of the biological reaction tank and is an area without nitrate or nitrite, and the phosphorus-accumulating microorganisms carry out the processes of absorbing organic matters and releasing phosphorus in the anaerobic zone; the anoxic zone is a non-aerobic zone of the biological reaction tank and is an area where nitrate or nitrite exists, and denitrification reaction can be carried out when sufficient organic matters are obtained; the aerobic zone is an oxygen charging zone of the biochemical reaction tank, the oxygen content in water is usually up to more than 1.0mg/L through aeration, and microorganisms in the zone can carry out degradation and nitration reactions of organic matters. The three areas are mutually matched, so that the sewage can complete the process of removing nitrogen and phosphorus and reducing pollutants such as BOD, COD and the like.
According to the above requirement for dissolved oxygen, the anaerobic zone and the anoxic zone cannot be oxygenated, and nitrate nitrogen is produced by the aerobic reaction, while the denitrification is completed in the anoxic zone and a certain amount of organic matter is required, so that the nitrate nitrogen produced in the aerobic zone needs to be returned to the anoxic zone. In the conventional design at present, the reflux amount of nitrifying liquid is generally 100-300% due to the limitation of reflux equipment, and the energy consumption is large.
For example, in a biochemical process without strict zoning such as an oxidation ditch, oxygen in a flowing aerobic zone of water is easily brought into an anoxic zone, so that the anoxic zone is difficult to form a stable anoxic environment, and therefore, although a certain denitrification effect is achieved, the achievement of the stable denitrification effect is difficult to achieve.
In the related technology, air lifting equipment with a large section and a low lift is adopted to promote the reflux of the nitrified liquid, but meanwhile, the air lifting mode is adopted, so that part of bubbles can be carried in the nitrified liquid.
