Description

Flow the apparatus and method of municipal sewage short distance nitration Anammox coupling denitrification dephosphorization continuously
Technical field
The present invention relates to flow continuously the method and apparatus of municipal sewage short distance nitration Anammox coupling denitrification dephosphorization, belong to Sewage treatment area.
Background technology
Along with the raising of people's living standard, the phenomenon of body eutrophication is day by day serious, this be primarily due in a large number rich in nitrogen, The sanitary sewage of the elements such as phosphorus and industrial wastewater discharge are in the natural water such as river, lake, beyond water body self-purification ability. Water quality deteriorates, and productive life and sustainable development on people cause serious impact.Therefore, water eutrophication Change problem has caused to be paid close attention to widely and payes attention to.In recent years, China has put into substantial contribution and has administered the water such as Taihu Lake, Dian Chi The eutrophication of body.But, the situation wanting to return to before polluting is the most difficult.Solve body eutrophication problem Basic method, is discharged into natural water after being sewage is carried out advanced nitrogen dephosphorization again.At present, how efficient taking off is being realized Energy consumption, expense is reduced while nitrogen dephosphorization, significant to Sewage Biological Treatment.
Short distance nitration is under aerobic condition, and ammonium oxidation is become nitrite nitrogen, Anammox to be to be with ammonia nitrogen by ammonia oxidation bacteria Electron donor, nitrite nitrogen is electron acceptor, and two kinds of nitrogens are converted into the bioprocesses of nitrogen and nitrate nitrogen simultaneously. The energy that this process produces is available for anaerobic ammonia oxidizing bacteria and under anaerobic survives.Anammox is the microorganism of autotrophy Journey, it is not necessary to adding Organic substance to maintain denitrification, sludge yield is low.Short distance nitration and anaerobic ammonia oxidation process, it is adaptable to High ammonia-nitrogen wastewater and the process of low COD/N stain disease.But, short distance nitration anaerobic ammonia oxidation process also can generate and about intake The nitrate nitrogen of total nitrogen concentration 10%, this not only increases water outlet total nitrogen concentration, also can cause the wasting of resources.
The principle of denitrification dephosphorization is then that Denitrifying Phosphate Accumulating Organisms under anaerobic utilizes the Organic substance in former water to synthesize interior carbon Source PHA, the simultaneously P elements in releaser, and under anoxic conditions, with nitrate for electron acceptor decomposer in PHA Complete excess and inhale phosphorus reaction, complete " carbon is dual-purpose " process, thus realize purpose nitrogen, phosphorus simultaneously removed from water. The proposition of denitrifying phosphorus removal technique solves polyP bacteria and denitrifying bacterium in the competition existed owing to carbon source in urban sewage is not enough Contradiction.
Stream municipal sewage short distance nitration Anammox coupling denitrification dephosphorization process is by denitrification dephosphorization and short distance nitration continuously Anammox organically combines, it is achieved that the purpose of sewage synchronous denitrification dephosphorizing.Denitrifying Phosphate Accumulating Organisms utilizes in sewage Organic substance and Anammox react the product nitrate nitrogen generated and carry out denitrification dephosphorization, complete " carbon is dual-purpose " process, Realize the efficient utilization of carbon source, save the expense adding outer carbon source, it is therefore prevented that the Organic substance suppression to anaerobic ammonia oxidizing bacteria, The product nitrate nitrogen that Anammox reaction generates is removed at anoxia section denitrifying phosphorus uptake simultaneously, efficiently utilize resource and reduce Effluent nitrate-nitrogen concentration.Therefore, stream municipal sewage short distance nitration Anammox coupling denitrification dephosphorization process is suitable for me continuously The low C/N of state, than city domestic sewage present situation, is advantageously implemented city domestic sewage and synchronizes advanced nitrogen dephosphorization.
Summary of the invention
The purpose of the present invention is exactly to reduce energy resource consumption and the expense of municipal wastewater treatment plant in removing sewage while nitrogen, P elements With, and propose the method and apparatus flowing municipal sewage short distance nitration Anammox coupling denitrification dephosphorization continuously.This device In, first sanitary sewage is entered the anaerobism section of biological carbon and phosphorous removal AA/O reactor by raw water box, and the denitrification of anaerobism section gathers Phosphorus bacterium utilizes PHA in the organic synthesis body in sanitary sewage, carries out anaerobic phosphorus release simultaneously；Then mixed liquor enters anoxia section, NO in Denitrifying Phosphate Accumulating Organisms recycling nitrification liquid backflow3 -Denitrifying phosphorus uptake is carried out, subsequently into aerobic section as electron acceptor Occur the part i.e. short distance nitration bacterium of short distance nitration reaction by part NH4 +It is converted into NO2 -, subsequently enter anoxia section, anchor at Anaerobic ammonia oxidizing bacteria on filler utilizes NH in mixed liquor4 +And NO2 -Anammox reaction is occurred to generate N2And NO3 -, so After sequentially enter follow-up aerobic section and anoxia section again, alternately realize autotrophic denitrification by short distance nitration and Anammox.? In good/hypoxia response district alternation procedure, Denitrifying Phosphate Accumulating Organisms continues to inhale phosphorus, and final realization removes nitrogen, the purpose of phosphorus in water.This side Method realizes short distance nitration with device under conditions of low-oxygen aeration, good anoxia replace, and utilizes filler effectively to hold simultaneously and stays enrichment to detest Anaerobic ammonium oxidation bacterium, is effectively increased biological carbon and phosphorous removal effect in the case of not additional carbon.
