Abstract
The invention discloses a device, a structure and a process for processing ammonia-nitrogen sewage by an aeration zeolite fluidized bed, wherein the device comprises an upward flow filter; a filter plate is arranged in the filter; a zeolite filling material is arranged above the filter plate, and an air pipe and a water feeding pipe are arranged below the filter plate; a water outlet is arranged above the zeolite filling material; and an exhaust pipe is arranged at the top of the filter. According to the device, the zeolite filling material is made to flow in water by aeration, in order to absorb the ammonia and nitrogen in the water by zeolite; meanwhile, zeolite absorbers rub against each other to result in surface peeling off, and the fallen fine particles with ammonia and nitrogen absorbed flow away along with the flow, so the surface of the zeolite filling material is continuously renewed to develop a sustainable absorption, and the zeolite filling material is not regenerated; therefore, the problems of limited absorption capacity, frequent regeneration in processing high-concentration ammonia-nitrogen sewage and limited application of the zeolite in the prior art are solved.
Description
Technical field
The invention belongs to the ammonia-nitrogen sewage process field, be specifically related to device, structures and technique that a kind of aeration zeolite thermopnore is processed ammonia-nitrogen sewage.
Background technology
The excessive emissions of ammonia nitrogen causes ocean and terrestrial water environment eutrophication, and ammonia-nitrogen sewage is processed and more and more caused concern.Ammonia and nitrogen pollution comes from sanitary sewage, garbage leachate and the trade effluent draining, and analysis is wide, and it is great to solve ammonia nitrogen processing question meaning.
The main method of processing ammonia nitrogen dirt, waste water has biochemical process and physico-chemical process.At present, biochemical process mainly is biological denitrificaion, and physico-chemical process mainly contains break point chlorination, air lift stripping and ion exchange method etc.
Sanitary sewage and the trade effluent that biodegradability is arranged are processed ammonia nitrogen and are mainly selected bio-denitrification technology.Biological denitrificaion requires sewage that suitable carbon-nitrogen ratio is arranged, otherwise not only denitrification effect is bad, also can affect organic matter removal.The sewage ammonia nitrogen excessive concentration, biological process is suppressed, such as coking chemical waste water, gourmet powder waste water, garbage leachate etc.Organic matter of sewage concentration is excessively low, does not have sufficient carbon source, and biological denitrification process can not carry out, and such as ammonium nitrate wastewater, containing wastewater from catalyst etc., has and takes to add methyl alcohol etc. as the method for carbon source, and running cost is very high.
Break point chlorination is the method for utilizing the ammonia react generation ammonia deamination in strong oxidizer chlorine and the water, causes the pollution of air, and the chlorine residue meeting of generation is influential to fish, so must set up except the chlorine residue facility.The air lift stripping need be adjusted the pH value of water in the strong basicity scope, also needs acid adding to adjust pH value after the processing and reaches emission standard, and the waste gas that the air lift stripping produces need absorb and wait processing, and absorption liquid reclaims or processing, complex process.Ion-exchange is to utilize positively charged ion in the material and the NH4 in the waste water
+Exchange to reach the purpose of removing ammonia nitrogen, but need to consider regeneration, and the processing of regeneration waste liquid.
Natural zeolite is because its special structure and characteristics has very strong selective adsorption capacity to ammonia nitrogen, and this point is familiar with by people already, and is used for the ammonia-nitrogen sewage processing.Its exchange capacity is much larger than gac and ion exchange resin.The processing up to standard and the lower ammonia-nitrogen sewage of city B-grade sewage advanced treatment isoconcentration that are mainly used at present sewage are processed, and main technique adopts filters or BAF.
China's natural zeolite is contained and is enriched quality better, and price is low, and natural zeolite has very strong Selective adsorption to ammonia nitrogen, it is the ideal material that ammonia-nitrogen sewage is processed, but the natural zeolite adsorptive power is limited, and it is frequent to process regeneration for high concentration ammonia nitrogen sewage, and its application is restricted.
