Abstract
The invention provides a producing method of removing sulfate ion agent from water, the raw materials for production is aluminum ash, renamed as cast aluminums production residue and lime, among, the content of Al2O3 in aluminum ash is over 50% and CaO in lime is equal to or more than 80%. The producing steps are: first disintegrate the aluminum ash and lime to 200 order, then mix them homogeneously at the weight rate of 1:1-1.4, calcine for 2-3 hours at the temperature of 720-950 Deg C. The method of removing sulfate ion agent from water in said invention is characterized by: the gain of raw material is easy, calcining heat is mild, manufacturing technique is simple, manufacturing time is short, the cost of production is low; said agent could effectively make drug-effect after being put into water in suspension and mixed for 30 minutes, the removing quantity of sulfate ion and the release quantity of said agent are stable, which could effectively control the content of sulfate ion in water after treatment.
Description
Affiliated technical field
The present invention relates to a kind of method of producing water treatment agent, especially a kind of method of producing sulfate ion medicament in the treating water.
Background technology
According to national water quality standard for drinking water, sulfate ion should be less than 250mg/L in the water, and many source qualities can not satisfy this index request both at home and abroad.The existence of sulfate ion is to cause the high one of the main reasons of permanent hardness index in the water in the water, it is the main nutrition source that sulphate reducing bacteria is grown fast in the water, also cause easily other metal ions particularly heavy metal ion dissolve in the water, therefore, along with the raising of people, remove the method for sulfate ion in the water and will more be paid attention to water quality requirement.
Process is to the literature search relevant with water treatment both at home and abroad, the method of sulfate ion mainly contains osmosis, reverse osmosis, ion-exchange etc. in the existing removal water, the medicament aspect has polymerize aluminum chloride, polymeric biacid iron ferro-aluminum, polymeric aluminium ferrum silicate etc. to play the flocculation agent of throwing out, these methods and flocculation agent can effectively be removed suspended substance and the colourity in the water, but sulfate ion is not almost had removal effect.
Summary of the invention
The purpose of this invention is to provide a kind of production method of removing sulfate ion medicament in the water.
The object of the present invention is achieved like this: with the aluminium ash is that cast aluminium products production waste residue, lime are raw material, wherein AL in the aluminium ash
2O
3Content more than or equal to 50%, in the lime CaO content more than or equal to 80%.
Further, the production stage of this medicament is: at first with two raw material separated pulverizing to 200 orders, back even in thorough mixing after the ratio proportioning of aluminium ash and lime weight ratio 1: 1～1.4, under 720～950 ℃ of temperature environments, calcined 2～3 hours then, discharging of calcining back and cooling the made medicament of the inventive method.
Further, the ulking thickness during the mixture calcining of aluminium ash and lime in stove is during greater than 50mm, and mixture must stir while calcine, and is even with assurance mixture sintering.
Further, mixture calcining is after 2～3 hours, should be after discharging chilling, the encapsulation in time of cooling back.
Because having adopted technique scheme, the mixture of aluminium ash, lime to generate a kind of in calcination process is the inorganic complex of main component with aluminium, calcium constituent, promptly with Ca
12Al
14O
33, Ca
4Al
2O
7, Ca
3Al
2O
6Be the mixture of main component, this mixture medicament efficiently sulfate ion in the planar water can make the sulfate ion concentration in the water drop to less than 10mg/L in conjunction with corresponding water technology.Utilize the inventive method to produce the medicament of removing sulfate ion in the water, raw material is obtained easily, and calcining temperature is moderate, concise production process, and the production time is short, and product cost is low; This medicament is thrown in pending water thorough mixing can bring into play drug effect about 30 minutes fully, and the injected volume ratio of the removal amount of sulfate ion and medicament is stable in the water, can control the content of water sulfate ion after processing effectively.
