Embodiment Construction

[0034] Refer to the attached figure 1 Specific embodiments of the present invention will be described in detail.

[0035] The present invention is provided with an incinerator 1, the bottom of the incinerator 1 is provided with a hydrogen inlet 2 and an air inlet 3, the upper part of the incinerator 1 is connected with a heat exchanger 4, and the heat exchanger 4 is connected with a second section through a gas delivery pipeline 7 The heat exchanger 5 and the second-stage heat exchanger 5 are connected with the exhaust fan 6 . Hydrogen and air enter from the bottom of the incinerator 1 respectively, and the high-temperature furnace gas generated after being ignited by the electronic igniter is discharged from the upper part of the incinerator 1, and passes through the first-stage heat exchanger 4 and the second-stage heat exchanger 5 in turn, and is discharged in the exhaust fan 6 discharged under the guidance.

[0036] The present invention is also provided with a waste wat...

Abstract

The invention provides a high-ammonia-nitrogen wastewater treatment method and device and solves technical problems of poor treatment effects, poor environment protection effects and high cost in existing high-ammonia-nitrogen wastewater treatment. Salt-containing high-ammonia-nitrogen wastewater is subjected to two-stage heat exchange by heat generated in hydrogen and air combustion, and heated wastewater is subjected to gas-solid separation to obtain double-salt solid used as a fertilizer; after a heat exchange process, ammonia-nitrogen-containing gas is mixed with hydrogen and air combustion flame to continue combustion at a certain temperature and decomposed into nitrogen and water, and part of furnace gas is exhausted through a draught fan after second-stage heat exchange. The high-ammonia-nitrogen wastewater treatment method and device can be widely applied to high-ammonia-nitrogen wastewater treatment.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a method and device for treating high ammonia nitrogen waste water. Background technique [0002] High ammonia nitrogen wastewater mainly comes from the disposal enterprises of chemical industry, metallurgy and circuit board etching waste liquid. Ammonia nitrogen is based on ammonium salt or NH 4 The form of OH exists in wastewater, and its NH 3 -N content is usually between 1-50g / L, which is highly polluted wastewater that is strictly prohibited to be discharged directly. There are currently two main domestic methods for the treatment of wastewater containing ammonium chloride, sodium chloride and organic ammonia nitrogen compounds: physicochemical method and biological denitrification method. [0003] 1. Physical and chemical method [0004] Physical and chemical methods are mainly divided into the following two types: [0005] (1) blow off method [0006] Under alkali...
