Background technology
Bodied ferric sulfate is a kind of new, high-quality, efficient iron salt class inorganic polymer flocculant, is mainly used in purifying water effect
Excellent, water quality is good, and without harmful substances such as aluminum, chlorine and heavy metal ion, also the water of non-iron-ion is nontoxic to transfer, harmless, peace
It is complete reliable, turbidity removal, decolouring, removing oil, dehydration, degerming, deodorization, except algae, remove COD, BOD and heavy metal ion in eliminating water the effects such as
Significantly etc..It is also used for Industrial Wastewater Treatment, such as dyeing waste water.
Attapulgite is a kind of aqueous magnalium carbonate clay mineral, and the basic structural unit of attapulgite is parallel to carbon
The silicon-oxy tetrahedron double-strand composition of axle, each interchain is connected by oxygen atom, and the interlayer up and down of each double-strand passes through one layer of magnesium original
The sexavalence coordination connection of son.The sensing (i.e. the angle top of silicon-oxy tetrahedron) of silicon-oxy tetrahedron active oxygen atom is upper and lower per tetrad
It is alternately arranged.Due to there is crystal duct in crystal structure, internal surface area is larger, thus with very strong physical absorption performance.
Road is reached in its Ph.D. Dissertation《Bodied ferric sulfate and ferric sulfate of polymerized silica are prepared and organically-modified research》In, utilize
Oxidizing process is prepared for a kind of bodied ferric sulfate, but its flocculating effect, turbidity removal rate need further raising.

Acrylamide VN835, shitosan, and carry the attapulgite of silver；
D. step c gained attapulgite is added in step a gained liquid, and adds aluminum sulfate, Polyethylene oxide, in 30-70
1h-6h is stirred at DEG C, is filtered, then in 30 DEG C of -50 DEG C of drying, grind to form powdery.
Described a kind of compound bodied ferric sulfate seawater flocculation agent and preparation method thereof, it is characterised in that curing time
It is all for 2-4.
The invention has the beneficial effects as follows：Add thiobacillus ferrooxidant as biocatalyzer in oxidizing process, safely may be used
By, energy-conserving and environment-protective；Bodied ferric sulfate is loaded using attapulgite, the intermolecular forces for causing flocculating agent molecule become
Change, so that adsorption layer is more firmly and tight, increase and improve the flocculating property of flocculant, flocculating effect strengthens；Heating
Attapulgite sulfuric acid waste immersion after activation can remove the impurity being distributed in attapulgite duct, dredge duct, carry
High attapulgite adsorptivity, decolourising property etc..Ethylene glycol can on attapulgite in-situ reducing silver nitrate, make the silver particles of generation
It is attached on attapulgite, gives the function of flocculant antibacterial, increases the service life, meanwhile, polyacrylamide VN835 not only may be used
To cooperate with turbidity removal together with bodied ferric sulfate, load of the silver particles on attapulgite can also be promoted；Tool prepared by the present invention
