Acrylamide VN835, and carry the attapulgite of silver, lanthanum；
D. by step c gained attapulgite, Fe3O4Powder, cyclodextrin are added in step a gained liquid, at 30-70 DEG C
Stirring 1h-6h, filters, and then in 30 DEG C of -50 DEG C of drying, grinds to form powdery.
Described a kind of Magnaglo composite polymeric ferric sulfate flocculant and preparation method thereof, it is characterised in that during curing
Between for 2-4 it is all.
The invention has the beneficial effects as follows：Add Thiobacillus ferrooxidans as biocatalyst 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
