Technical field
The present invention is a kind of novel environment friendly medicament reducing various heavy leaching concentration, belongs to heavy metal-polluted soil processing skill
Art field.
Background technology
The situation is tense for heavy metal pollution at present, and improvement is carried out to it and has become current very urgent problem.Using steady
The leaching concentration for determining chemical drug agent to reduce the heavy metal in soil and all kinds of danger wastes is considered a kind of effective
Restorative procedure almost accounts for the 20-30% of all heavy metal pollution class rehablitation projects, therefore the use of stabilization agent becomes the skill
The key factor of art.The General Principle of chemical stabilization method is by the way that chemical stabilization medicament is added into pollutant, is allowed to and dirt
Dye object chemically reacts, and free state heavy metal is allowed to form stable substance and lose toxicity.This method is to chemical agent
It is more demanding.For a long time, most chemical stabilization medicaments can only continue some months even several days to the stablizing effect of soil,
It can not ensure that the compound generated after administering can steadily in the long term exist in nature, in environmental change, heavy metal is easy quilt
It reactivates, generates secondary pollution.
Meanwhile the stabilization agent of current domestic and international market production is mainly solid powder medicament, uses solid powder
Medicament is repaired at end, and there is also following disadvantages：1. when using powder medicine processing contaminated soil, medicament and soil incorporation time are longer,
Uniformity is poor, and additive amount of medicament is larger, and curing time is relatively long.2. powder medicine is used for heavy metal soil treatment, lead to
Showering can only be often used, due to using showering, quantities is big, and engineering time is long, and rehabilitation cost is higher.
Invention content
In view of the deficienciess of the prior art, reducing the new of various heavy leaching concentration it is an object of the present invention to provide a kind of
Type ring protects medicament, to solve the problems mentioned in the above background technology.
To achieve the goals above, the present invention is to realize by the following technical solutions：A kind of reduction various heavy
The novel environment friendly medicament of leaching concentration, is made of following raw material：Calcium sulfide, bloodstone, vulcanized sodium, iron powder, ferrous sulfide, chlorination

Further, the bentonite be one kind using bentonite as raw material, utilize the lamellar knot of montmorillonite in bentonite
Structure and its it can be swollen in water or organic solvent and be dispersed into colloid clay characteristic, organic covering is inserted by ion exchange technique
Agent, manufactured organobentonite.
Further, to produce a concentration of 4% or so sodium sulfide solution of blanc fixe byproduct in process as raw material,
Double effect evaporator inspissation is squeezed into after 23% with pump, into after the deferrization of people's agitator tank, carbon removal treatment, is squeezed into evaporator with pump and is evaporated alkali
Liquid reaches concentration, after being sent to roller internal water cooling but formula pelleter being made, through screening, obtains the vulcanized sodium in raw material.
Further, iron content pickle or waste hydrochloric acid are placed in reaction kettle device, while iron powder or iron filings are added, acid with
Iron occurs the thermal energy that exothermic reaction generates and is preheated to material, and catalyst is then added and is passed through oxygen, is then turned on circulating pump, makes
Reaction solution recycle 3-5 hours, it is to be polymerized that the reaction was complete, by reaction solution be transferred to precipitation tank for precipitation or with filter type to product into
Row separation and enrichment, form the iron chloride in raw material.
Further, the raw materials such as lime stone are calcined and generates lime and carbon dioxide, water digestion lime is added to generate hydroxide
Calcium, then be passed through carbon dioxide, carbonization milk of lime generate precipitation of calcium carbonate, then precipitation of calcium carbonate after being dehydrated, drying again through stone
Grey flour mill crushes the lime being just made in raw material.
Further, using potato dry powder, the starch dregs of rice and amyloid agricultural and sideline product as raw material, match culture medium, under normal pressure
Boiling is cooled to inoculation temperature, accesses koji, is packed into koji plate fermentation, the technique for then using calcium carbonate neutralization and sulfuric acid solution
Zymotic fluid is extracted, the citric acid in raw material is obtained.
Further, it using quartzy rock powder and caustic soda as raw material, in autoclave, is reacted under 0.6~1.0 MPa steam,
Generate the sodium metasilicate in raw material.
Beneficial effects of the present invention：A kind of novel environment friendly medicament of reduction various heavy leaching concentration of the present invention, can
So that the heavy metal in contaminated soil is reduced to the heavy metal of low price immobilization, to lose its biological effectiveness, soil is realized
The reparation of earth, the soil environment quality after reparation meet China's GB15618-1995 secondary standards requirement.
Specific implementation mode
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
The present invention provides a kind of technical solution：It is a kind of reduce various heavy leaching concentration novel environment friendly medicament, by with
Lower raw material is constituted：Calcium sulfide, bloodstone, vulcanized sodium, iron powder, ferrous sulfide, iron chloride, lime, bentonite, citric acid and silicic acid
Sodium.
Bentonite is one kind using bentonite as raw material, using montmorillonite in bentonite lamellar structure and its can in water or
Swelling is dispersed into colloid clay characteristic in organic solvent, and organic coverture is inserted by ion exchange technique, manufactured organic
Bentonite.
Using a concentration of 4% or so the sodium sulfide solution for producing blanc fixe byproduct in process as raw material, squeezed into pump double
Evaporator inspissation is imitated to after 23%, into after the deferrization of people's agitator tank, carbon removal treatment, evaporator evaporation lye is squeezed into pump and reaches concentration,
After being sent to roller internal water cooling but formula pelleter being made, through screening, the vulcanized sodium in raw material is obtained.
Iron content pickle or waste hydrochloric acid are placed in reaction kettle device, while iron powder or iron filings are added, acid is put with iron
