Description
Technical field
The present invention relates to a kind of wastewater processing technologies, and in particular to a kind of flucculation process for removing particulate matter in waste water belongs to
In environment protection field.
Background technique
The strand of polyacrylamide is very long, its amide groups can, absorption affine with many substances form hydrogen bond, this just makes
It can build bridge between the particle of absorption, and several or even dozens of particle is made to link together, generation floc sedimentation, under accelerated particle
It is heavy.This is similar with general flocculation mechanism, i.e., a molecule can adsorb several particles simultaneously, is pulled together them, settles rapidly.
Flocculation is extremely complex physics, chemical process, and present majority think that Flocculation Mechanism is two kinds of cohesion and flocculation
Mechanism.Coacervation process is that colloidal solid takes off process that is steady and forming tiny condensate；And flocculation process is to be formed carefully
Small condensate generates the process of the flocculate (i.e. floc sedimentation) of large volume under bridging (bridge formation) effect of flocculant.But
Existing compound material for water treatment is to pollutant substantially based on physical action, and which results in its capacity that flocculates is small, absorption is up to full
The slow disadvantage with the time, and it is unable to satisfy the requirement of industrial application.
And due to the development of nanotechnology, many nano materials are widely used, such as inorganic additive, polymer nano
Rice corpuscles etc.；A large amount of uses of these nano-sized particles objects are also produced and are much received while promoting material property progress
Rice grain waste, these nano particles have and can much be discharged into water, form nanoparticles pollution, these tiny nanoparticles
Son is much larger than micron particles object to the harm of human body；But existing water treatment technology is substantially invalid to small sized particles object.
Summary of the invention
The object of the present invention is to provide a kind of wastewater treatment method based on flocculant, in the method, flocculant flocculation effect
Fruit is strong, effectively can form flocculant with the particulate matter of the various sizes in waste water, substantially increase sewage treating efficiency.
To achieve the above object of the invention, the technical solution adopted by the present invention is that：The flocculation of particulate matter in a kind of removal waste water
Method includes the following steps：
（1）The preparation of flocculant, boiled silk is soluble in water, tetramethyl-ammonium iodide, manganese acetate and nitric acid is then added
Cobalt is uniformly mixed, back flow reaction 8 hours, is then dried to obtain fibroin membrane；Then fibroin membrane is small in 190~200 DEG C of processing 2
When after Freezing smashing obtain silk fibroin powder；Then in ethanol by silk fibroin powder dispersion, methyl orthosilicate and 2- ammonia are added
Base butyric acid and diethyl phosphite stir 3 hours at room temperature, add silane coupling agent, filter after stirring 1 hour and obtain solid
Compound；Sodium acrylate, 2- acrylamide-2-methylpro panesulfonic acid are added to the water, stirred 10 minutes, bis- (2,3- rings are added
Oxygroup cyclopenta) ether, is stirred 15 minutes；Then solid chemical compound and azodiisobutyronitrile are added, 90 DEG C are reacted 4 hours, finally
It is dried to obtain flocculant；
（2）By step（1）Flocculant dispersion in ethanol, obtain mixed liquor；Then by mixed liquor according to 50~80g/
The additive amount of ton is added in waste water；The removal that floccule body completes particulate matter in waste water is then demultiplex out.
In the present invention, in step (1), the boiled silk, tetramethyl-ammonium iodide, manganese acetate, cobalt nitrate mass ratio be 1
:（0.1~0.2）:（0.3~0.5）:（0.4~0.6）.Manganese acetate during compatible with silk, can be reacted with cobalt nitrate
Corresponding manganese cobalt/cobalt oxide is generated, the flocculating effect of inorganic core in flocculant can be increased.
In the present invention, in step (1), the silk fibroin powder, methyl orthosilicate, 2-amino-butyric acid, diethyl phosphite, silicon
The mass ratio of alkane coupling agent is 1:（0.5~0.8）:（0.03~0.05）:（0.03~0.05）:（0.05~0.06）.Utilize phosphine
Hydrogenation can form stable, active organic matter layer in mineral surfaces, be conducive to flocculant outer layer copolymer and core
The promotion of the interface interaction power of inorganic matter, greatly improves the stability of flocculant.
In the present invention, in step (1), the sodium acrylate, 2- acrylamide-2-methylpro panesulfonic acid, bis- (2,3- epoxies
Cyclopentyl) ether, solid chemical compound, azodiisobutyronitrile mass ratio be 1:（0.7~0.8）:（0.08~0.09）:（0.3~
0.5）:（0.005~0.006）.By the addition of epoxy monomer, the flocculation ability of flocculant outer layer copolymer is increased；Simultaneously
Conducive to the promotion of the interface interaction power of polymer and inorganic core.
In the present invention, in step (2), the mass concentration of flocculant is 10%~15% in the mixed liquor.First by flocculant
Dispersion in ethanol, adds waste water, is conducive to the dispersed homogeneous degree for improving flocculant；Made simultaneously using the interface of ethyl alcohol and water
Firmly, increase the connection function between flocculating agent molecule, be conducive to the uniformity of particle removal；And increases particulate matter and form flocculation
The probability of body finally removes floccule body using conventional means, completes the removal of waste particles object.
The method of particulate matter is simple and effective in removal waste water disclosed by the invention, and the flocculant property utilized is stablized, dispersion
Floccule body can be formed with the particulate matter in waste water on a large scale in waste water, can especially remove the small particulate matter of partial size, go
Except rate is up to 95% or more.
