Description
Technical field
The utility model relates to wastewater treatment equipment, especially relates to a kind for the treatment of unit of ammonia-containing water.
Background technology
Develop rapidly along with industrial or agricultural, water resource pollution problem is day by day serious.Ammonia nitrogen is one of principal pollutant of industrial and life contaminated water.Ammonia nitrogen enrichment can cause body eutrophication, makes microorganism amount reproduction in water, reduces dissolved oxygen in water, causes fish kill, lake even can be caused to dry up and wait environmental pollution, have great harm to ecotope and human body health.
Current researchist both domestic and external has carried out a lot of research to process ammonia nitrogen waste water, and the method for conventional process ammonia nitrogen waste water comprises: air stripping method, chemical precipitation method, break point chlorination method, biological denitrificaion method and membrane separating method etc.
Air stripping method blasts in ammonia nitrogen waste water by air, makes the ammonia nitrogen in waste water transfer to gas phase through liquid-gas interface from liquid phase, finally reach the effect removed.Patent CN102030438A adopts air stripping method and coupled ion exchange operation processes ammonia nitrogen waste water, the method overcomes simple blow-off method inefficient shortcoming when low ammonia nitrogen concentration.Patent CN104261501A is processed city garbage percolate ammonia nitrogen by air stripping method, and ammonia-nitrogen desorption rate is more than 80%.But it is high that air stripping method exists running cost, equipment is perishable, easily causes the shortcomings such as secondary pollution.
Chemical precipitation method mainly utilizes Mg
2+, PO4
3-react to generate precipitate Deng the ammonia nitrogen in material and waste water, then filtering will be precipitated, thus remove the ammonia nitrogen in waste water.Patent CN100384754C utilizes chemical precipitation method for treating ammonia nitrogen waste water, and the method can operate continuously and treatment effect is high.Patent CN1493528A is by chemical precipitation method for treating ammonia nitrogen waste water, and ammonia nitrogen removal frank is more than 95%.Patent CN102690001A is by fused(calcium magnesium)phosphate process high ammonia-nitrogen wastewater, and ammonia-nitrogen removal rate can reach 70% ~ 80%.Chemical precipitation method treatment process is simple, but rises due to the expensive processing cost that causes of the precipitation agent added.
Break point chlorination method adds the materials such as clorox in ammonia nitrogen waste water, by the NH in waste water
3-N is oxidized to nitrogen thus the processing method of removal of ammonia and nitrogen.Patent CN103011441A is by break point chlorination method process ammonia nitrogen waste water.Patent CN102863109A is by break point chlorination method and in conjunction with stripping process and electrochemical reaction, and this technique ammonia nitrogen removal is effective, process structure is simple.Break point chlorination method can process Low Concentration Ammonia Containing Wastewater well, and simple to operate, but high-concentration ammonia nitrogenous wastewater treatment effect is poor.Meanwhile, because the method needs to use the oxygenants such as clorox, processing cost is caused to increase.
Biological denitrificaion method mainly utilizes microorganism under biochemical condition, is nitric nitrogen, then becomes gaseous nitrogen to overflow from water nitrate-nitrogen reduction by denitrification process, finally reach the object of denitrogenation by the mineralized nitrogen in waste water.
Patent CN1562806A utilizes bio-denitrification technology to devise corresponding operational path, makes treated ammonia-nitrogen sewage reach the emission standard of national regulation.Patent CN103508615A is by biological denitrificaion method and in ammonia nitrogen waste water, add biologic packing material improve NH_3-N treating effect.Patent CN101549907A utilizes biological deamination method, designs a kind of membrane biologic reaction equipment process ammonia nitrogen waste water of industrial waste water with high ammoniac nitrogen process.Biological denitrificaion method needs to use a large amount of microorganism, so require high to waste water quality, occupation area of equipment is large, and operational condition is harsh.
Film absorption dehydrogenating technology is based on membrane separation technique and in conjunction with chemical absorption process, the general acidic solution that adopts, as absorption agent, absorbs ammonia nitrogen by the chemical reaction of absorption agent and ammonia.Patent CN104609588A adopts film absorption technique and removes high salt high ammonia-nitrogen wastewater in conjunction with reverse osmosis and positive cementation process flow process, and the method ammonia nitrogen rate of recovery is high, and product water water quality is good.Patent CN104609587A by film absorption process process ammonia nitrogen waste water, and to permeate and absorption liquid after cooling and crystallizing process processing reaction by nanofiltration, just.Patent CN104058519A adopts Using Multistage Membranes assembly series connection process ammonia nitrogen waste water, and the decreasing ratio of total ammonia nitrogen can reach 50 ~ 99%.Patent CN101508500A utilizes film coagulate contact reactor to reclaim ammonia nitrogen from percolate.Film absorption dehydrogenating method treatment effect is good, and ammonia-nitrogen removal rate is high.Free ammonia in ammonia nitrogen waste water to be separated by vacuum diaphragm deamination technology and Ammonia recovery is become the ammoniacal liquor of high density by patent CN103896354A.Patent CN103183393A, by vacuum diaphragm deamination technical finesse ammonia nitrogen waste water, achieves the recycling of resource.
This kind of patent is owing to adopting the acidic solutions such as sulfuric acid as absorption agent, a large amount of ammonium sulfate dilute solution containing dilute sulphuric acid can be formed in treating processes, can not directly be recycled as fertilizer, also be difficult to be processed by other techniques, to a certain extent, secondary pollution is caused.
