Description
Technical field
The present invention relates to a kind of methods for realizing advanced nitrogen by denitrifying ammoxidation MBBR technique, belong to sewage treatment
Technical field is suitable for sanitary sewage disposal and handles containing nitrate wastewater, improves nitrogen removal efficiency, solve nitrogen and phosphorus pollution, protect

Background technique
Eutrophication caused by China's water body nitrogen and phosphorus pollution is serious.
Common sanitary sewage belongs to the low ammonia nitrogen concentration waste water of low temperature, and conventional short distance nitration+Anammox technology exists
Bottleneck, short distance nitration are difficult to realize and maintain, anaerobic ammonia oxidizing bacteria slow growth, and the generation cycle is long.
Denitrifying ammoxidation carries out part anti-nitration reaction (NO3- NO2-) and anaerobism i.e. in single-reactor
Ammoxidation reaction, electron acceptor NO2--N in anaerobic ammonium oxidation process from denitrification process NO3--N reduction,
It can be difficult to the problem of obtaining with effective solution anaerobic ammonium oxidation process NO2--N, and can be by anaerobic ammonium oxidation process
The NO3--N of generation is removed in situ, thus TN removal rate is higher, while being coupled Anammox reaction and being enabled this technique
Carbon source and aeration energy consumption are further saved, can be used for strengthening the nitrogen phosphorus ligands effect of conventional activated sludge process.
