CN104084120A - Industrial waste-modified ammonia scavenger - Google Patents

Abstract

The invention aims to provide an industrial waste-modified ammonia scavenger. In order to achieve the purpose, the adopted technical scheme is that the ammonia scavenger is prepared by the following steps: crushing coal cinder; adding 1 to 5mol/L hydrochloric acid solution into a certain amount of coal cinder; stirring and soaking for 8 to 24 hours on a magnetic stirring device; washing the treated coal cinder by using clean water; soaking the soaked solid matter into a sodium chloride solution for 12 to 24 hours; pouring supernatant out; washing the solid matter to be neutral by using deionized water; drying the solid matter at 105 DEG C and bottling for later use.

Description

A kind of ammonia remover that utilizes trade waste modification

Technical field

The present invention relates to ammonia adsorbing domain, be specifically related to a kind of ammonia remover that utilizes trade waste modification.

Background technology

Ammonia, inorganic compound, is gas under normal temperature, the gas of colourless irritant stench, soluble in water, when ammonia is water-soluble, amino molecule becomes a hydration ammonia with hydrone by Hydrogenbond, one hydration ammonia energy fraction is ionized into ammonium ion and hydroxide ion, therefore ammoniacal liquor shows alkalescent, the mucous membrane of energy skin ambustion, eyes, respiratory apparatus, people sucks too much, can cause lung swelling, thus dead.

Due to a large amount of generations of municipal sewage and industrial wastewater, and exhaust emissions, cause environment more and more to worsen.Situation day by day serious, causes control imperative.

Absorption method is to process a kind of important physical chemistry method of harmful in waste water and waste gas and difficult degradation pollutant, and active carbon is the most frequently used sorbing material, but due to lack of material, cost is higher, regeneration is difficult etc., and reason is restricted its application.Taking industry and agricultural wastes as raw material, preparation and exploitation are cheap, to replace active carbon be the important directions that sorbing material is studied to efficient adsorption material.

Summary of the invention

The object of this invention is to provide a kind of ammonia remover that utilizes trade waste modification, the lack of material existing to overcome prior art, the shortcoming that cost is high.For achieving the above object, the technical solution used in the present invention is as follows:

By broken coal furnace ground-slag, get a certain amount of pulverized slag, add the hydrochloric acid solution of 1-5mol/L, on magnetic stirring apparatus, stir and soak 8-24h, then rinse with clear water, then soaked solid matter is put into sodium chloride solution and soak again 12-24h, pour out supernatant, extremely neutral with deionized water rinsing, 105 DEG C of oven dry, bottle for subsequent use, obtain this ammonia remover.

There is following distinguishing feature in the present invention:

(1) invent described ammonia remover, raw material sources are extensive, cheap;

(2) invent described ammonia remover preparation method simple, adsorption rate is high;

(3) invent the stable performance of described ammonia remover, the life-span is long, can preserve for a long time use.

detailed description of the invention:

Embodiment 1:

By broken coal furnace ground-slag, take 100 g flyash, add 10% phosphoric acid solution 2L, under room temperature, flood 3h, then dry.After dry, solid matter is risen to the 300 DEG C of insulation 2h of temperature that pre-set from room temperature, be cooled to room temperature, take out end product and be washed with distilled water to neutrality, dry, bottle for subsequent use, obtain this ammonia remover.

Embodiment 2:

By broken coal furnace ground-slag, take 100 g flyash, add 30% phosphoric acid solution 2L, under room temperature, flood 12h, then dry.After dry, solid matter is risen to the 500 DEG C of insulation 2h of temperature that pre-set from room temperature, be cooled to room temperature, take out end product and be washed with distilled water to neutrality, dry, bottle for subsequent use, obtain this ammonia remover.

Embodiment 3:

By broken coal furnace ground-slag, take 100 g flyash, add 50% phosphoric acid solution 2L, under room temperature, flood 24h, then dry.After dry, solid matter is risen to the 700 DEG C of insulation 2h of temperature that pre-set from room temperature, be cooled to room temperature, take out end product and be washed with distilled water to neutrality, dry, bottle for subsequent use, obtain this ammonia remover.

Claims (1)
