Abstract
The invention discloses a potato-residue-containing composite polyferric sulfate flocculant and a preparation method thereof. The invention is characterized in that the potato-residue-containing composite polyferric sulfate flocculant is prepared from the following raw materials in parts by weight: 2-4 parts of potato residue, 25-30 parts of FeSO4.7H2O, 1-2 parts of starch, a right amount of sulfuric acid waste liquid, 2-3 parts of iron protoxide Thiobacillus, 4-6 parts of oxydol, 3-5 parts of silver nitrate, 3-5 parts of polyacrylamide VN835, 15-25 parts of attapulgite, 25-35 parts of ethanediol and 25-30 parts of water. The attapulgite is utilized to support the polyferric sulfate, so that the acting force among flocculant molecules changes; and thus, the adsorption layer is firmer and tighter, thereby increasing the flocculability of the flocculant and enhancing the flocculation effect. The bioflocculant extracted from potato residues is matched to enhance the water purification effect of the composite flocculant.

Acrylamide VN835, starch, and carry the attapulgite of silver；
E. step d gained attapulgite, step a gained biological flocculant are added in step b gained liquid, at 30-70 DEG C
Lower stirring 1h-6h, filters, and then in 30 DEG C of -50 DEG C of drying, grinds to form powdery.
Described a kind of composite polymeric ferric sulfate flocculant containing potato residues and preparation method thereof, it is characterised in that ripe
The change time is that 2-4 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
To cooperate with turbidity removal together with bodied ferric sulfate, load of the silver particles on attapulgite can also be promoted；Coordinate from potato residues
