Description
Technical field
The invention belongs to water environmental protection technical field, it is related to a kind of water purification PACS flocculant, more particularly to a kind of high-purity high
Basicity nanoscale PACS flocculant and preparation method thereof.
Background technique
PACS product is the high efficiency composition product that High-purity Polyaluminum Chloride introduces sulfate ion.Its existing production method is
Temperature-pressure in a kettle will contain Al2O364% or so gel aluminum hydroxide in a kettle be lower than the equivalent thickness of aluminium salt
Acid dissolves out molten aluminum under conditions of temperature-pressure, and one-step synthesis obtains limpid bright aluminium polychloride liquid after separation.Its
Reaction are as follows:
Al(OH)3+HCl→Al(OH)2Cl+H2O
2Al(OH)2Cl+HCl→Al2(OH)3Cl3+H2O
Al2(OH)3Cl3→〔Al2(OH)nCl6-n〕M
The aluminium polychloride general formula of M < 10.
The various compound states of hydroxyl polymeric aluminum belong to aluminium ion hydrolyze, be complexed in the solution, peptization, precipitating, crystallization
Reaction intermediate, it is also to be classified according to the molecular weight of the degree of polymerization.In earliest PAC solution be added sulfate radical from
Son is that Japanese studies, and charge density is slightly lower, and zero point is in PH7.5, and traditional PAC and aluminum sulfate, charge density
Lower, in pH value up to switching to negative electrical charge after neutral, it is many that the charge neutrality of flocculant and net catch function reduction, for this purpose, domestic
PAC product be also initially added into some sulfate radicals, form later PACS product.
As the domestic Chinese Academy of Sciences is in the modal developmental research of hydroxy Al, from the exploration of theory and practice, chemically product
By Al in the mechanism of purification13Research extraction risen to from the point of view of nanometer technology material, with Al13It is combined and detached from extraction
During, a part for being applied to nanometer technology synthesis of sulfate ion, and examine sulfate radical and hydroxy Al raw
The form composition of solution is detected at sediment, it may be assumed that Al13O4(OH)24(H2O)+7 12(general molecular formula), shows sulfate radical and hydroxyl
Aluminum solutions existing chemical dynamics process, fundamental reaction under different shape are as follows:
Ala+n SO2- 4→Al- a(SO4)nTransient response generates dissolution complex compound
Alb+n SO2- 4→Al- b(SO4)nSlow reaction generates crystal precipitation
Alc+n SO2- 4→Al- c(SO4)nFast reaction generates amorphous sediment object
Add BaProduct salt and calcium displace Alb material.
The crystalline structure formed are as follows:
Na〔Al13O4(OH)24(H2O)12(SO4)4〕
Al- b(SO4)n+nBa(NO3)2n→Al- b(NO3)2n+nBaSO4
Isolate BaSO4Precipitating obtains: Al- b(NO3)2n→Alb→Al13
In addition, the process of existing preparation method due to producing usually as shown in Figure 1, still, during the preparation process, synthesize
Condition and mode it is different, as soon as especially compounded in the production of step material, controlled in production basicity condition have it is very big
Difference.From the point of view of the production technology of Japan, it is to generate sodium aluminate by aluminium hydroxide alkali soluble, then by CO2Gas acidification generates hydrogen
Aluminium oxide, then one section of material with dissolving with hydrochloric acid polymerization as aluminium polychloride, add sulfate radical SO2 -4, fundamental reaction formula are as follows:
Al(OH)3+Na OH→NaAl(OH)4
2NaAl(OH)4+CO2→Al(OH)3↓+Na2CO3+H2O
2Al(OH)3+(6-n)HCl→〔Al2(OH)n Cl6-n〕+(6-n)H2O
So this technique produces the basicity adjustability of a step material with regard to larger.And China directly uses gel aluminum hydroxide
It is reacted with hydrochloric acid, liquid material basicity can not be done up, and the excessive hydrolytic polymerization degree for causing formation mechanism of acidity is inadequate, condensate
Molecular weight do not increase yet, then be added SO4Root improves AL13The content of nanotechnology is just highly difficult in actual production.Japan
It is also to have any problem that basicity, which reaches 60% or more, when same One-step production polymeric aluminum.Therefore, day originally provides basicity
Between 45%-60%, and containing sulfate radicals are no more than 3.5%, and the degree of polymerization of product is improved with sulfate radical.It is in fact, sulfur-bearing
Acid group AL/SO4Theoretical value basicity the most suitable degree of polymerization should be had in 70%-75%.For this purpose, every country is in reality
In water treatment applications, all make every effort to be improved the PACS product basicity that a step produces.
1 Japan of table is compared with China's PACS technical standard
Compare from the technical standard of Japan and China, in high-purity PACS product, gap is very big for we.It alkalizes first
Degree is since production technology is different, and actual variance has 15%, and the difference of sulfate radical is just bigger, because the molten aluminium hydroxide of acid is done
Method, the sulfate of addition is not only without improving basicity, instead due to SO4Hydrogen ion concentration, which increases, in root makes high-purity PAC liquid
The decline of body basicity, so that basicity be made to can not improve, the simple polymeric molecular weight and molecular weight of hydroxy Al is used in water process
Middle available hydroxyl degree aluminium polymerization degree of hydrolysis is inadequate, affects the charge neutrality in colloid chemistry, the function such as catches, builds bridge, adsorbs in net
It can be not so good as the products such as the PACV of high basicity in body.For this purpose, domestic many factories are in SO-4Addition in Japanese technology, all
SO-4Radical content has been increased between 2.0%-3.0%, and PACS product has apparent improvement, but the raising of basicity is still
The project of one tackling key problem.Because it is equally known that Al/SO4Synthesis be condition that PACV aluminium salt cannot have nanometer technology,
So capturing Al/SO4Changing basicity is a very big technical problem.Therefore, for current PACS product both domestic and external
Nanoscale crystalline structure form, improve hydroxyl polymeric degree and change basicity and increase inorganic polymer amount, here it is current
The very difficult break-through point of water purification agent PACS product.
