Description
Technical fieldThe present invention relates to processing method of industrial waste water, particularly relate to method for treating ammonia-nitrogen wastewater and device.
Background technologyAmmonia nitrogen waste water mainly shows two aspects for the harm of human and environment: first ammonia nitrogen is to health effects; Ammonia nitrogen in the water can convert nitrite under certain condition to; If long-term drinking; Nitrite in the water will become NSC 223080 with protein bound, and this is a kind of strong carcinogen, and is totally unfavorable to HUMAN HEALTH.It two is ammonia nitrogen influences to ecotope, and it mainly is free ammonia that ammonia nitrogen plays damaging effect to aquatic organism, and its toxicity is bigger tens times than ammonium salt, and increases with alkalescence.PH value and the water temperature of ammonia nitrogen toxicity and Chi Shui have substantial connection, and generally speaking, pH value and water temperature high toxicity more are strong more, to the similar nitrite of the harm of fish.Ammonia nitrogen has acute and chronic branch to the harm of aquatic organism.Chronic ammonia nitrogen is poisoned to endanger and is the reduction of ingesting, poor growth, tissue injury and the conveying of reduction oxygen between tissue.Fish are relatively more responsive to ammonia nitrogen in the water, but ammonia-nitrogen content Gao Shihui causes fish kills.Acute ammonia nitrogen poisons to endanger: aquatic organism shows as excited, and balance in water is twitched severe patient even death.Ammonia nitrogen has caused pollution to water body, makes fish kills, forms the health of nitrite harm humans.So ammonia nitrogen is an important indicator of estimating water pollution and " self-cleaning " situation.
The existing ammonia nitrogen waste water treatment process methods that add alkali ammonia still process that adopt do not reclaim and put into atmosphere more, and this is polluted-water not just, but still atmosphere pollution.

Compared with prior art, the present invention adopts the bipolar membrane electrodialysis process, have the integrated level height, energy-conservation, do not consume any soda acid salt, do not produce technique effects such as waste liquid, environmental benefit and remarkable in economical benefits.
Description of drawings
Fig. 1 is the present invention produces acid and ammoniacal liquor with ammonia nitrogen waste water method and a device synoptic diagram.
EmbodimentBelow in conjunction with preferred embodiment the present invention is done further detailed description.
Present embodiment is to use ammonium chloride waste-water to be raw material production hydrochloric acid and ammoniacal liquor.As shown in Figure 1; Produce the device of acid and ammoniacal liquor with ammonia nitrogen waste water; Comprise electrolyzer, ammonia nitrogen waste water circulation groove, sour circulation groove and ammoniacal liquor circulation groove (ammonia nitrogen waste water circulation groove, sour circulation groove and ammoniacal liquor circulation groove are not shown in the figures), said electrolyzer is divided into three compartments with Bipolar Membrane BP, cationic exchange membrane A, anion-exchange membrane C and Bipolar Membrane BP successively.Said ammonia nitrogen waste water circulation groove communicates with compartment between anion-exchange membrane and the cationic exchange membrane; Ammonium chloride concentration electrolysis in the ammonia nitrogen waste water circulation groove is up to standard to emit during to emission concentration 10ppm; When not reaching emission concentration, electrolysis in the compartment between anion-exchange membrane and the cationic exchange membrane is delivered in circulation.Said ammoniacal liquor circulation groove communicates with compartment between Bipolar Membrane and the cationic exchange membrane; Ammonia concn in the ammoniacal liquor circulation groove surpasses 10%; Deliver to the production scene and use, ammonia concn does not reach at 10% o'clock, and then circulation is delivered in the compartment between Bipolar Membrane and the cationic exchange membrane.The acid circulation groove communicates with compartment between Bipolar Membrane and the anion-exchange membrane; Acid concentration in sour circulation groove surpasses 10%; Just deliver to the production scene and use, the acid concentration in the sour circulation groove does not reach 10%, in the compartment between the Bipolar Membrane that then circulates and the anion-exchange membrane.Bipolar Membrane is also claimed bipolar membrane, is specific ion exchange membrane, and it is by an anode membrane and the compounded yin, yang composite package of cavity block.The characteristics of this film are under the effect of DC electric field, the H between yin, yang film composite bed
2O is dissociated into H
+And OH
-And respectively through cavity block and anode membrane, as H
+And OH
-Ion source.Bipolar Membrane is divided by macroscopical film bulk structure can be divided into homogeneous phase Bipolar Membrane and out-phase Bipolar Membrane.
Ammonium chloride is the salts solution of easily ionizable, and the waste water that will contain ammonium chloride feeds the compartment between anion-exchange membrane and cationic exchange membrane.After applying direct current, the interfacial layer generation water of Bipolar Membrane (BP) dissociate positively charged ion NH
4 +Pass through the same OH of cationic exchange membrane C
-In conjunction with forming ammoniacal liquor, negatively charged ion Cl
-Pass through the same H of anion-exchange membrane
+In conjunction with forming hydrochloric acid.Reaction when Bipolar Membrane is dissociated: 2H
2O → 2H
++ 2OH
-Because H
2→ 2H
++ 2e, theoretical current potential are 0V; 2H
2O+2e → H
2↑+2OH
-, theoretical current potential is 0.828V, so this reaction potential is two reaction sum: 2H
2O → 2H
++ 2OH
-, theoretical current potential is 0.828V.And O is arranged
2And H
2The electrolysis theoretical voltage of water is 2.057V when separating out, and wherein the 1.229V voltage consumption is at O
2And H
2Generation on, the 0.828V voltage consumption is on the dissociation reaction of water.
Theoretical value needs the voltage of 0.828V to act on the Bipolar Membrane both sides, just can make water decomposition become H
+And OH
-, but actual existence owing to membrane resistance, interfacial layer resistance, actual potential is higher than theoretical value.However, Bipolar Membrane water decomposition method is produced soda acid and is still had clear superiority because it not energy expenditure in unwanted side reaction.Therefore have following advantage: handling for ammonia nitrogen waste water provides new thinking and terms of settlement, utilizes the combination of Bipolar Membrane and one pole film dexterously, and less energy-consumption ground changes ammonium chloride waste-water into hydrochloric acid and ammoniacal liquor is reused for the production scene; Process non-oxidation and reduction reaction; No side reaction product such as O
2And H
2Only need 1 counter electrode, practice thrift investment; Need not insert electrode at every compartment, device volume is little.
Instance: use the bipolar membrane electrodialysis device of specification as 300mm x 100mm; Totally 6 groups (1 pair of yin, yang film and 1 Bipolar Membrane are 1 group) membrane stacks, anode is that titanium is coated with ruthenium electrode, negative electrode is a stainless steel plate; Ammonium chloride solution is carried out the electrodialysis test; Process 10% hydrochloric acid and 10% ammoniacal liquor from 10% ammonium chloride solution, chloride solid power consumption 1600kwh per ton has obtained good effect.
Above content is to combine concrete optimal technical scheme to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
