Description
Technical field
The invention belongs to water, waste water, technical field of sewage, be specifically related to the flocculation or the precipitation of suspended impurity.
Background technology
Used flocculation agent mainly contains five big classes in the processing of trade effluent at present, comprises low-molecular inorganic flocculation agent, inorganic polymer flocculant, natural organic high-molecular flocculant, synthetic organic polymer flocculation agent, microbial flocculant.The low-molecular inorganic flocculation agent mainly contains ferrous sulfate, iron protochloride, Tai-Ace S 150, aluminium chlorohydroxide etc., inorganic polymer flocculant mainly contains polymerize aluminum chloride, bodied ferric sulfate, because the inorganic flocculating agent raw material sources are abundant, cost is low, easy to use, effect is obvious, occupy an leading position in flocculant product always.
However, still there are shortcomings such as consumption is big, flocculation rate is slow, performance is single, PH subject range is narrow, the low temperature result of use is bad in inorganic flocculating agent, very inapplicable as the sewage big to sewage quantity, that flow velocity is fast, very not obvious etc. to the tap water that contains heavy metal ion and wastewater treatment efficiency.
On the other hand, many flocculation agents are liquid, store in the tank filling usually and transportation, are not easy to transportation, and have intensive corrodibility to be easy to etching apparatus.For industrial sewage, oilfield sewage, contain heavy metal ion sewage processing very inapplicable.
Summary of the invention
One object of the present invention is to overcome the shortcoming of above-mentioned flocculation agent, provides that a kind of flocculation rate is fast, flco is closely knit, precipitate and separate efficient height, inorganic polymer flocculant that use range is wide.
Another object of the present invention is to provide the inorganic polymer flocculant that a kind of dissolution rate is fast, be convenient to storage and transport.
Further purpose of the present invention is to provide a kind of preparation method of inorganic polymer flocculant.
For achieving the above object, it is to be that raw material is made by following component and weight proportion for the solution that the present invention adopts:
The A component is the hydrochloride of Mg, the hydrochloride of Fe, 10～30% hydrochloric acid soln compositions of the polysalt hydrochlorate of Al, in its proportioning, the polysalt hydrochlorate of the hydrochloride of the hydrochloride of Mg: Fe: Al: the weight ratio of 10～30% hydrochloric acid solns is 1: 1～3: 1～3: 7～15, or the A component is the vitriol of Mg, the vitriol of Fe, 10～30% sulphuric acid soln compositions of the polymerised sulphur hydrochlorate of Al, in its proportioning, the polymerised sulphur hydrochlorate of the vitriol of the vitriol of Mg: Fe: Al: the weight ratio of 10～30% sulphuric acid solns is 1: 1～3: 1～3: 7～15, and the A components contents is 20～70%.
The B component is the polysalt hydrochlorate of Al or the polymerised sulphur hydrochlorate of Al, and its content is 10～60%.
The C component is 10～30% acidic solutions of soluble silicate, and its content is 20～60%.
The preferred weight proportioning of each raw material of the present invention is:
A component 20～50%
B component 20～60%
C component 20～30%
The optimum weight proportioning of each raw material of the present invention is:
A component 50%
B component 20%
C component 30%
C component soluble silicate of the present invention is water glass or potassium silicate, and the acidic solution of C component soluble silicate is hydrochloric acid soln or sulphuric acid soln.
In proportioning of the present invention, its main ingredient is that the content of the hydrochloride of the polysalt hydrochlorate of Al or polymerised sulphur hydrochlorate and iron or vitriol is higher, accelerated to be suspended in the flocculation rate of dirt in the sewage, increased the alumen ustum settling velocity, reduced sludge volume, and the flco after flocculation is closely knit, has added soluble silicate in proportioning of the present invention, improved the stability and the flocculating effect of product, be applicable to that low temperature uses.
Another solution that the present invention adopts is: this flocculation agent be shaped as ointment shape.
Its preparation method of solution that also has that the present invention adopts is: the A component of liquid state is joined in the reactor, add the C component with heater heats to 30 ℃～110 ℃, being stirred to agitator becomes homogeneous solution, add the B component then, stir with agitator again, make its uniform mixing, stop to stir cooling gradually and become the ointment shape, after quality control standards (QCS) check of the present invention, packing gets product of the present invention.
To join the preferred Heating temperature scope after the A component be 40 ℃～100 ℃ to the C component among the preparation method of the present invention.
To join the optimum heating temperature after the A component be 70 ℃ to the C component among the preparation method of the present invention.
Adopt the ointment shape flocculation agent of the present invention consignment test unit of preparation method of the present invention preparation to carry out simultaneous test, test-results shows: it is fast that flocculation agent of the present invention has flocculation rate.Flco is closely knit.Precipitate and separate efficient height.Advantages such as use range is wide can be used for the processing of oilfield sewage.The processing of trade effluent, and the removal of arsenic and fluorine is handled in the tap water.
