Description

Integrated short-cut nitrification-anaerobic ammoxidation reaction device

Technical Field

The utility model relates to the technical field of sewage treatment, in particular to an integrated short-cut nitrification-anaerobic ammonia oxidation reaction device.

Background

The treatment of high ammonia nitrogen wastewater has been one of the important research directions in the field of industrial wastewater treatment, and the denitrification treatment is performed on the high ammonia nitrogen wastewater by using an anaerobic ammonia oxidation (Anaerobic ammonium oxidation, anammox) reaction, and under the anoxic condition, ammonia is used as an electron donor, nitrous nitrogen is used as an electron acceptor, so that the ammonia is oxidized into nitrogen, and the oxygen supply amount is saved by more than 60% compared with the whole-process nitrification (ammonia oxidation into nitrate). The short-cut nitrification-anaerobic ammonia oxidation (PN/A) process derived on the basis can realize autotrophic denitrification under the condition of no carbon source, and breaks through the basic theoretical concept in the traditional biological denitrification process.

Currently, short-cut nitrification-anaerobic ammoxidation processes are roughly divided into two-stage and one-stage processes. In the two-stage short-cut nitrification-anaerobic ammonia oxidation reaction process, two reactors with different operation conditions are usually required in the high ammonia nitrogen water treatment process, for example, a Chinese patent application with publication number of CN116282528A is provided with a short-cut nitrification tank and an anaerobic ammonia oxidation tank, sewage pumped into a control system firstly enters the short-cut nitrification tank, ammonia nitrogen in water is converted into nitrite nitrogen under the condition of inputting oxygen, and the nitrite nitrogen and the rest ammonia nitrogen enter the anaerobic ammonia oxidation tank together and are converted into nitrogen under the action of anaerobic ammonia oxidation bacteria (AnAOB).

The one-stage short-cut nitrification-anaerobic ammoxidation process is to perform short-cut nitrification and anaerobic ammoxidation in one reactor simultaneously and to realize denitrification treatment in sewage through the combined action of Ammonia Oxidizing Bacteria (AOB) and AnAOB. An integrated short-cut nitrification-anaerobic ammoxidation sewage treatment domestication device provided in chinese patent application publication No. CN109987703a, for example, adopts an intermittent step aeration operation mode in one reactor, and implements sewage treatment and domestication in a multistage aerobic/anoxic alternate operation reaction mode.

In the prior one-stage process, two bacteria, namely AOB and AnAOB, play an important role together, the AOB performs a short-range nitrification function, ammonia nitrogen is converted into nitrosamine, and the AnAOB converts the ammonia nitrogen and the nitrosamine into nitrogen, thereby performing a denitrification function. Therefore, the biomass stabilization of AnAOB and AOB is a key factor for realizing efficient denitrification and stable operation of PN/A. But AOB grows relatively fast, with doubling times typically around 10 days, while AnAOB grows very slowly, with doubling times typically between 20 and 30 days. The problem with this one-stage process is that on the one hand, AOB grows faster than AnAOB and more short-cut nitrification occurs to convert ammonia nitrogen to nitrous nitrogen, which is not consumed by AnAOB; on the other hand, the generated nitrogen drives the sludge to float upwards and simultaneously drives AnAOB to drain and run away along with the effluent; the nitrosamine is continuously accumulated, and then the AnAOB is inhibited, and finally the whole system is crashed.

Accordingly, it is desirable to provide an apparatus that enables a one-stage short-cut nitrification-anaerobic ammonia oxidation reaction system to be stably operated.
