The short-cut nitrification technology is characterized in that the nitrification process is controlled at a nitrite nitrogen stage by a certain means without further oxidation, and the generated nitrite nitrogen can be used as a substrate of anaerobic ammonia oxidation reaction. The denitrification can also be directly carried out, which not only saves the aeration quantity, but also correspondingly saves a great part of carbon source. According to the anaerobic ammonia oxidation technology, ammonia nitrogen is directly used by anaerobic ammonia oxidation bacteria to react with nitrite nitrogen to generate nitrogen, so that not only is the oxidation process of ammonia nitrogen omitted, but also the oxidation process of nitrite nitrogen into nitrate nitrogen is omitted, and obviously, the anaerobic ammonia oxidation reaction is an energy-saving and efficient denitrification mode.
The shortcut nitrification process can provide a substrate for the anaerobic ammonia oxidation process, so the coupling of the two is a research hotspot, but the balance of the two is difficult to maintain in the integrated process, not only can dissolved oxygen required by the shortcut nitrification process generate an inhibition effect on anaerobic ammonia oxidation bacteria under certain conditions, but also organic matters in inlet water exceed a certain content and generate adverse effects on the anaerobic ammonia oxidation bacteria, and the anaerobic ammonia oxidation bacteria are autotrophic bacteria, have slow growth speed and are easily influenced to be in a disadvantage position, so the advantages of the shortcut nitrification and anaerobic ammonia oxidation cannot be played at all.
The partial nitrification process and the anaerobic ammonia oxidation process are separated in the partial nitrification and anaerobic ammonia oxidation sectional process, and ammonia oxidizing bacteria and anaerobic ammonia oxidizing bacteria can grow in respective optimal growing environments by adjusting parameters in the two reactors, so that the treatment efficiency is improved, and a source can be conveniently and quickly found and treated when the effluent quality is in problem.
