Abstract
The invention discloses a fly ash composite polyferric sulfate flocculating agent and a preparation method thereof. The fly ash composite polyferric sulfate flocculating agent is characterized by being prepared from the following raw materials in parts by weight: 2 to 4 parts of fly ash, 25 to 30 parts of FeS04 7H20, 1 to 2 parts of red soil, a proper amount of sulphuric acid waste liquid, 2 to 3 parts of thiobacillus ferrooxidans, 4 to 6 parts of hydrogen peroxide, 3 to 5 parts of silver nitrate, 1 to 2 parts of iron chloride, 3 to 5 parts of polyacrylamide VN835, 15 to 25 parts of attapulgite, 25 to 35 parts of glycol and 25 to 30 parts of water. The attapulgite is used for loading the polyferric sulfate, so that the acting force between flocculating agent molecules changes, so that an adsorption layer is firmer and compactor; the flocculating performance of the flocculating agent is increased and improved; the flocculating effect is enhanced. The fly ash and the high-molecular flocculating agent are compounded, i.e., the sewage treatment effect of the agent is enhanced; the fly ash is changed from waste materials into valuable materials; the integral utilization is realized.

Preparation Method, belongs to field of environment engineering technology.
Background technology
Bodied ferric sulfate is a kind of new, high-quality, efficient molysite class inorganic polymer flocculant, is mainly used in purifying water effect
Excellent, water quality is good, and without harmful substances such as aluminium, 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, de-oiling, dehydration, it is degerming, deodorant, 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.
The content of the invention

C. step b gained attapulgite and flyash, red soil are added in ethylene glycol solution, suspension are obtained after ultrasonic disperse,
Silver nitrate, polyacrylamide VN835 are added, after immersion 2-5h, centrifugation, washing is vacuum dried under the conditions of 25-55 DEG C, obtains
Absorption polyacrylamide VN835, and carry attapulgite, flyash, the red soil mixture of silver；
D. step c gained mixture is added in step a gained liquid, 1h-6h is stirred at 30-70 DEG C, filtered, then
In 30 DEG C of -50 DEG C of drying, powdery is ground to form.
A kind of described flyash composite polymeric ferric sulfate flocculant 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 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；The present invention is by flyash
With high polymer coagulant compounding, that is, the effect of chemicals treatment sewage is enhanced, make flyash turn waste into wealth again, obtained comprehensive profit
With.
