Description
Technical field
The invention belongs to water-treatment technology fields, and in particular to a kind of composite flocculation agent and preparation method thereof.
Background technique
It is shifted along with global electronic complete product to China, semiconductor also accelerates the paces to China's transfer.Partly lead
Body market brings various demands and opportunity to China, and many Semiconductor enterprises establish production base in China.Semiconductor is raw
It produces to the transfer of China and not only brings economic interests, while also bringing new environmental problem.In semiconductor production process,
Some waste water and exhaust gas can be generally generated, wherein especially the most serious with the harm of fluoride waste.
The content of existing composite flocculation agent, sulfate radical is big, increases the difficulty of subsequent biochemical processing；And the corruption to pipeline
Corrosion is stronger.
Summary of the invention
Technical problem to be solved by the present invention lies in view of the above shortcomings of the prior art, provide a kind of composite flocculation
The content of agent, sulfate radical meets industrial requirements, small to pipeline corrosion, and flocculating effect is good.
In order to solve the above technical problems, the technical solution adopted by the present invention is that, a kind of composite flocculation agent is contained by following quality
The raw material of amount is prepared: aluminum sulfate 30-45%, aluminium polychloride 5-10%, phosphoric acid 5-10%, hydrochloric acid 10-15%, and surplus is
Water, gross mass content 100%.
Further, it is prepared by the raw material of following mass content: aluminum sulfate 40%, aluminium polychloride 7%, phosphoric acid
7%；Hydrochloric acid 13%, surplus are water, gross mass content 100%.
The invention also discloses above-mentioned preparation method, this method is as follows: weighing above-mentioned each raw material, water is added in aluminum sulfate
In stir evenly, then sequentially add phosphoric acid and hydrochloric acid, stir evenly, be eventually adding aluminium polychloride, stir evenly, filtering is
Obtain filtrate finished product.
A kind of composite flocculation agent of the present invention has the advantages that (1) coagulation performance is good, and precipitating is fast, high-efficient, defluorination effect
It is good.(2) content of sulfate radical meets industrial requirements, and treated, and trade effluent meets discharge standard, is not required to increase additional place
Science and engineering sequence.(3) chloride ion content is in safe range, small to pipeline corrosion compared with conventional flocculant.
Specific embodiment
A kind of composite flocculation agent of the present invention, is prepared by the raw material of following mass content: aluminum sulfate 30-45%, polymerization
Aluminium chloride 5-10%, phosphoric acid 5-10%, hydrochloric acid 10-15%, surplus are water, gross mass content 100%.
Further, it is prepared by the raw material of following mass content: aluminum sulfate 40%, aluminium polychloride 7%, phosphoric acid
7%；Hydrochloric acid 13%, surplus are water, gross mass content 100%.
A kind of above-mentioned composite flocculation agent the preparation method is as follows: weigh above-mentioned each raw material, aluminum sulfate is added to the water and is stirred
It mixes uniformly, then sequentially adds phosphoric acid and hydrochloric acid, stir evenly, be eventually adding aluminium polychloride, stir evenly, filter up to filtering
Liquid finished product.
In the present invention, technical hydrochloric acid, concentration 36% are selected；What phosphoric acid was selected is industrial phosphoric acid, concentration 85%.
Each implementation such as table 1 of composite flocculation agent in the present invention:
Each embodiment of table 1
Using the composite flocculation agent and current market sales of flocculant prepared in embodiment 3 respectively to fluorine-containing useless
Water is handled, and fluorinion concentration is 240PPM in the fluoride waste of processing, and first adding calcium hydroxide tune PH is 9.0 or so, then
Various concentration composite flocculation agent and flocculant available on the market are added, after putting into each flocculant, is measured fluorine-containing in waste water
Amount, contrast test data are as shown in table 2:
2 contrast test data of table
From 2 data of table it is found that under same dosage, the defluorination effect of the composite flocculation agent in the present invention is substantially better than city
The two kinds of flocculants sold.
Then the composite flocculation agent prepared in embodiment 3 and two kinds of flocculants of market sale are compared, test sedimentation
Speed, fluoride waste fluorinion concentration 240ppm, the pH=2.8 used, first adding calcium hydroxide tune PH is 9.0 or so, then is thrown
Add 2000ppm embodiment 3 and market sale flocculant, observes floc settling velocity, shown in experimental data table 3:
The test of 3 sinking speed of table
As can be seen from Table 3, after the flocculant of isodose is added, composite flocculation agent wadding body in embodiment 3 it is heavy
Reduction of speed degree is obviously faster than commercially available flocculant speed.
Use the composite flocculation agent and market sale flocculant process fluoride waste of embodiment 4, after processing, SO in waste water4 2-
And Cl-The data of content are as shown in table 4:
4 SO of table4 2-And Cl-The data of content
As shown in Table 4, fluoride waste, after processing, SO in waste water are handled using the composite flocculation agent in embodiment 44 2-With
Cl-Content is lower.
