Embodiment Construction

[0030] Accompanying drawing is a kind of specific embodiment of the present invention.

[0031] The technique for continuously removing ammonia nitrogen light component organic matter and salt of the present invention comprises the following process steps:

[0032] Step 1: Distillation in the rectification tower kettle: the waste water from outside the boundary area is heated by the preheater, and then transported to the rectification tower kettle for rectification treatment. The ammonia vapor is introduced into the condenser from the top of the rectification tower kettle to condense After treatment, it is evaporated through the evaporating tank of the tower kettle, and the ammonia gas outlet and the upper part of the rectification tower kettle are branched and pressed into the ammonia gas outlet and the upper part of the rectification tower kettle through the tower kettle. ; The bottom liquid of the rectification tower kettle is pressed into the rectification tower kettle thr...

Abstract

The invention belongs to the technical field of wastewater treatment, and in particular relates to a process and system for continuously removing ammonia nitrogen light component organic matter and salt. A method for removing ammonia nitrogen and desalination of waste water, characterized in that it comprises the following process steps: step 1: distillation in a rectification tower; step 2: primary evaporation; step 3: secondary evaporation; ... Step n: n-stage evaporation: Step n+1: final evaporation. The invention relates to an equipment system used in the ammonia nitrogen removal and desalination process of waste water, which comprises a rectification tower kettle, a primary evaporation tank, a secondary evaporation tank and an n-stage evaporation tank. Beneficial effects of the present invention: 1) recovery of light component organic matter in waste water, especially ammonia water, and high purity; 2) final salt in waste water is finally converted into solid powder, reducing solid waste discharge; 3) light and light removal Re-coupling reduces the energy consumption of the device by 40% to 70%; 4) After the waste water is delightened and desalted, the clean water obtained can be used as process water and returned to the system for recycling, reducing water consumption.

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...
