Abstract
The invention provides an integrated anaerobic ammonia oxidation reinforced endogenous denitrification SBBR advanced nitrogen removal method, and belongs to the field of biological treatment of sewage. The system comprises a domestic sewage tank and an SBBR. The method is characterized in that domestic sewage enters the SBBR; the organic matter in sewage is utilized for removing nitrate nitrogen produced by previous reaction cycle through denitrification by denitrifying bacteria; the rest organic matters are stored in bacteria to be synthesized into an internal carbon source; aeration is carried out after the reaction is finished; the integrated anaerobic ammonia oxidation reaction (synchronous short-process nitrifying anaerobic ammonia oxidation reaction) is performed on a biomembrane, thus ammonia nitrogen in sewage can be removed, and little nitrate nitrogen can be produced; the stirring is carried out after the reaction is finished, and the denitrifying bacteria are subjected to internal carbon source denitrification, so as to further reduce the concentration of nitrate nitrogen in water. According to the method, the advantages of the integrated anaerobic ammonia oxidation method and a sequencing batch biofilm reactor process are played; meanwhile, the organic matters in incoming water are fully utilized. Therefore, advanced nitrogen removal of the low-carbon-nitrogen-ratio domestic sewage can be achieved through single system; the operation is simple; the energy is saved.
Description
technical field [0001] The invention relates to a method for integrated anaerobic ammonium oxidation enhanced endogenous denitrification SBBR deep denitrification method, which belongs to the technical field of sewage biological treatment. Background technique [0002] With the increasing eutrophication of water bodies and the increasingly stringent water quality index system, denitrification and phosphorus removal of sewage, especially denitrification, has become a hot spot in water pollution control. The biological denitrification process of traditional multi-stage equipment is widely used in sewage denitrification, but there are problems such as easy loss of nitrifying bacteria, need to add carbon source or alkalinity, prone to sludge bulking, long process flow, and high infrastructure investment costs. question. For this reason, the present invention provides a method of combining the advantages of integrated anammox (i.e. synchronous short-range nitrification anammox) ...
