Technology and device for continuously removing light-component ammonia nitrogen organic matters and salts

Abstract

The invention belongs to the technical field of wastewater treatment, and particularly relates to a technology and a system for continuously removing light-component ammonia nitrogen organic matters and salts. A technological method for removing the ammonia nitrogen and the salts from wastewater is characterized by comprising the following technological steps: 1, distilling in a rectifying tower;2, performing first-stage evaporation; 3, performing second-stage evaporation; ...n, performing nth-stage evaporation; n+1, performing final-stage evaporation. An equipment system used by the technology for removing the ammonia nitrogen and the salts from the wastewater comprises the rectifying tower, a first-stage evaporation tank, a second-stage evaporation tank and an nth-stage evaporation tank. The invention has the beneficial effects as follows: 1), the light-component organic matters, especially ammonia water, in the wastewater, are recycled, and the purity is high; 2), the salts in thefinal wastewater are finally converted into solid powder, so that emission of solid wastes is reduced; 3), through coupling of light component removal and heavy component removal, the running energy consumption of a device is reduced by 40-70%; 4), After the light components and the salts are removed from the wastewater, the obtained clean water can return to the system as technological water andis recycled, so that the water consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, and in particular relates to a method for removing ammonia nitrogen and desalting waste water and an equipment system used therefor. Background technique [0002] Industrial wastewater is a common industrial pollutant in the chemical production process. If it is discharged directly, it will damage our living environment and seriously threaten our health. The common alkaline chemical wastewater containing NH4 can reduce its pollution to the environment through optimized treatment, but the traditional treatment process is not thorough in the treatment of alkaline chemical wastewater containing NH4, and the processed products are not pure, which cannot achieve waste purpose of use. Contents of the invention [0003] In order to solve the above-mentioned problems and make up for the deficiencies of the traditional technology, the present invention provides an efficient, thorough, saf...
