Description
Technical field
The utility model belongs to sewage treatment equipment field, is specifically related to a kind of device with Integrated Membrane Technology treatment of nitric acid ammonium waste water.
Background technology
Treatment of nitric acid ammonium waste water mainly contains following several at present: blow-off method, biochemical process, ion exchange method and electroosmose process etc.Stripping rule need to add chemical agent and regulate pH value, and after stripping in waste water ammonium salt residual quantity too high, the secondary pollution problems to atmosphere in addition.Biochemical process be by wastewater collection to biochemistry pool, with bacterium, ammonium salt is decomposed, finally form nitrogen.In biochemical reaction process, need to add carbon source and bacterial classification, and ammonium salt concentration is slightly high in water, when ammonia nitrogen reaches 500mg/L, bacterial classification will be dead, cannot carry out biochemical reaction.Ion exchange method is spent ion exchange resin absorption ammonium nitrate, but regenerative operation is frequent, also will process rinse water, not too convenient.Electroosmose process can be by the most of recover ammonium nitrate in waste water, but after processing, ammonia nitrogen concentration residual in water is also too high, can not reach the index of ammonia nitrogen 10mg/L and total nitrogen≤30mg/L in the water of promulgating national requirements for environmental protection for 2011.Can not discharge also and cannot reuse ，Gei manufacturing enterprise cause very large puzzlement.
Electrodialysis is the old technology of decades of having used in desalination field, and many investigators find that electrodialyzer is in the situation that water intermediate ion is few, can be in the intermembranous generation water decomposition reaction of ion-exchange, and water decomposition becomes H
+and OH
-ion, the ion being used in make up water, they become the carrier of electric charge, and this reaction is referred to as polarization reaction.After electrodialyzer polarization reaction occurs, can consume a large amount of electric energy, cause the working efficiency of electrodialyzer to reduce, effluent quality declines, power consumption increases, it is not high that therefore general electrodialyzer makes pure electrical conductivity of water, and therefore present desalination field electroendosmosis is analysed technology and progressively by reverse osmosis technology, replaced.But in the field for the treatment of of nitric acid ammonium waste water, electrodialytic technique is compared still and is had comparative advantage with additive method.
When electrodialytic technique is processed waste water, at the electrodialyzer latter end of plural serial stage, due to the most of ammonium nitrate in water, conductive ion is removed, and in water, conductive ion seldom, polarization reaction just very easily occurs.Make like this ammonium nitrate in water remove not exclusively, can not reach national requirements for environmental protection, the seal means of electrodialyzer film is simpler in addition, mainly by the resilient seal between film and film, after work for some time, different film convergent-divergents are inhomogeneous, cause the distortion of electrodialyzer membrane stack, intermembranous string water, dense hydroecium solution crossfire is to freshwater room solution, make effluent quality variation, these are all its shortcomings that is difficult to overcome.
Reverse osmosis is the membrane separation technique growing up in nearly decades, aspect seawater and brackish water desalination, the processing of large-sized boiler supplementary feed, be used widely, also for the separated and concentrated aspect of dairy products and fruit juice and biological and biochemical preparation, and the preparation aspect of tap water and high purity water.Reverse osmosis technology is also applied in field of waste water treatment in recent years, but while having people to attempt reverse osmosis technology to be applied to ammonium nitrate wastewater and to process, finds that reverse osmosis membrane is very high to the transmitance of ammonium nitrate.According to Introduction of Literatures, reverse osmosis membrane is to NH
4 +the clearance of ion is 70～90%, to NO
3 -the clearance of ion is 50～75%.That is to say that reverse osmosis membrane is to NH
4 +the transmitance 10～30% of ion, to NO
3 -the transmitance of ion is 25～50%.This is 99% to compare with reverse osmosis membrane to the clearance of NaCl, and this brings very large difficulty to the engineering that will realize the wastewater treatment that all removes ammonium nitrate, makes China there is no so far reverse osmosis applications in the precedent for the treatment of of nitric acid ammonium waste water.
China patent of invention ZL200910177557.1 discloses a kind of electric deionizing method and device that ammonia nitrogen waste water is used that reclaim, the case history that reclaims ammonium nitrate wastewater shows, electric deionizer is more adapted to the ammonium nitrate wastewater of low concentration and processes, and high density ammonium nitrate wastewater concentrated aspect, from concentrated effect, reverse osmosis technology is more applicable.
At present during electrodialytic technique treatment of nitric acid ammonium waste water, filter and adopt fiber rod to filter in its pretreatment technology in addition, can remove the particulate matter that is greater than 5 μ m, its filtering accuracy awaits further raising.In administering ammonium nitrate wastewater field, not yet used ultra-filtration membrane art breading.
In pre-treatment, adopt left and right, acid-base neutralisation regulator solution pH value to 6.5～7.Acid-base neutralisation also has the complicated defect with increasing ammonium nitrate concn in waste water of adjustment operation.
