Abstract
The invention discloses a treatment method for high-concentration ammonia nitrogen in urine waste water. The treatment method comprises the following steps of: smashing and sieving limonite, immersing particles in concentrated hydrochloric acid and a saturate potassium hydroxide methanol solution sequentially, separating the particles under the action of an applied magnetic field to obtain a sediment, adding oxygen malononitrile in the sediment to perform polarization on the sediment, then immersing the sediment in an organic composite denitrifier containing methyl ten-butyl ether, ethylene oxide and the like for 30-50 minutes, washing the sediment for three times with deionized water, and drying the sediment in the presence of nitrogen protection to obtain a magnetic adsorption nanometer material with the organic composite denitrifier. The treatment method for the high-concentration ammonia nitrogen in the urine waste water can be used for realizing the effect of high removing capacity of the combination of the organic composite denitrifier and an air stripping method, and further solving the problem of secondary pollution caused by ammonia emissions in the treating process of the organic composite denitrifier.
Description
Technical field
The present invention relates to a kind of processing waste water middle and high concentration ammonia nitrogen method, particularly a kind of processing urine waste water middle and high concentration ammonia nitrogen method.
Background technology
Today of 21 century, water closet has but become a main root of contaminate environment.Water closet makes the Urban water supply of lack of water more nervous on the one hand; People drop into a large amount of funds again and build sewage collecting and treatment system on the other hand, and nitrogen and phosphorus account for about 80% and 50% of nitrogen in the municipal effluent, phosphorus load respectively in the human urine, and most of the nitrogen exists with the form of ammonia nitrogen in the urine; Though the composition of urine can satisfy the demand of plant-growth to nutritive substance; But will cause body eutrophication when a large amount of ammonia nitrogen waste waters enter water body, cause water body black smelly, even to crowd and biological generation toxic action; So ammonia nitrogen waste water has caused the attention of environmental protection territory to the influence of environment.
At present, people have adopted the whole bag of tricks to handle urine waste water middle and high concentration ammonia nitrogen, and gas-phase catalysis and supercritical water oxidation method are wherein arranged; Though these two kinds of methods have and can fundamentally improve water quality, defectives such as the big and heat dissipation capacity of oxygen-consumption is big are arranged, in addition; Advantages such as kind method has clearance high in addition, and denitrogenation method is simple, but have the place of blemish in an otherwise perfect thing to exist; For example, patent publication No. is CN101475251, and title is that " the compound denitrfying agent and the denitrogenation method of concentration ammonia nitrogen waste water in a kind of the processing " is to be joined in the waste water by organism and the composite compound denitrfying agent that forms of inorganics through handle; Carry out in the aeration tank or in the stripping tower; Though have the denitrfying agent raw material to be easy to get, dosage is little, denitrogenation method is simple; Can drop to the middle concentration ammonia nitrogen waste water that is lower than 10000mg/L below the 0.5mg/L, clearance is up to the characteristics more than 99.99%.But be to combine with blow-off method, this method can cause ammonia to get into atmosphere and cause secondary pollution, and because other waste water complicated component does not have concrete specific aim, also not enough to some extent aspect environmental protection.
Based on sustainable development idea; Aspect the high-concentration ammonia nitrogenous wastewater processing; Not only to pursue the environmental improvement target of efficient denitrification; Also to pursue energy-conservation province and consume, avoid higher level environmental economical profit targets such as secondary pollution, be only and administer the more satisfactory technological development direction of high-concentration ammonia nitrogenous wastewater.
Summary of the invention
The object of the present invention is to provide a kind of processing urine waste water middle and high concentration ammonia nitrogen method; Can reach on the basis of compound denitrfying agent combination blow-off method effect at above-mentioned " the compound denitrfying agent and the denitrogenation method of concentration ammonia nitrogen waste water in a kind of the processing "; Method through the organic compound denitrfying agent nano adsorption material treatment of high concentration ammonia nitrogen of magnetic; Overcome the discharging of ammonia nitrogen; Both do not had deposition and generated, solved the secondary pollution problem that organic compound denitrfying agent combines blow-off method treatment of high concentration ammonia nitrogen waste water to be caused again.
For achieving the above object, the concrete technical scheme that the present invention takes is:
(1) gets limonite earlier and pulverize, sieve, get 100～120 order particles;
(2) particle of pulverizing is soaked through concentrated hydrochloric acid, saturated potassium hydroxide methanol solution successively, and under externally-applied magnetic field, separate, get throw out;
(3) add the oxygen propane dinitrile in the throw out and carry out polar, to strengthen throw out surface hydrogen bond action power;
(4) pickling, alkali are soaked and polarize after nano material immerse in organic double solvents, stir 30～60min;
(5) post precipitation is dried under the nitrogen protection condition with washed with de-ionized water 3 times;
(6) absorption of the magnetic after will drying nano material is that 50～100ppm is added in the gourmet powder waste water by mass ratio, stir 15～30min after, separation gets final product under externally-applied magnetic field.
Said organic compound denitrfying agent be in methyl tert-butyl ether, oxyethane, ethyl vinyl ether, trityl alcohol, propyl carbinol, crotonaldehyde, octanal, the capraldehyde more than three kinds or three kinds.
Said organic compound denitrfying agent, by quality ratio:
Methyl tert-butyl ether 10～60%, oxyethane 10～70%, octanal 20～70%,
Trityl alcohol 20～70%, propyl carbinol fourth 10～70%, olefine aldehydr 10～60%,
Capraldehyde 10～60%, ethyl vinyl ether 10～60%.
The present invention with the clear superiority that organic compound denitrfying agent combines blow-off method treatment of high concentration ammonia nitrogen waste water to be had is:
(1) can not produce ammonia entering atmosphere does not have the deposition generation yet, has avoided secondary environmental pollution;
(2) through the oxygen propane dinitrile magnetic Nano material is polarized after, strengthened surperficial hydrogen bond action power, strengthened with waste water in the binding ability of ammonia or ammonia radical ion;
(3) to gourmet powder waste water water quality situation, selected for use organic compound denitrfying agents such as methyl tert-butyl ether, oxyethane, ethyl vinyl ether, trityl alcohol, propyl carbinol, crotonaldehyde, octanal, capraldehyde that its magnetic Nano material is carried out modification, with strong points.
