Abstract
The invention discloses a high-efficient composite powder-shaped sewage treating agent for desizing waste water and preparation method of the high-efficient composite powder-shaped sewage treating agent. The sewage treating agent comprises tartaric acid, ursodesoxycholic acid, 2- chloromandelic acid, calcium sulfate, magnesium carbonate, calcium carbonate, ferric trichloride, calcium oxide, sodium borate. The method is to orderly and evenly mix above matters. Compared with the prior art, the treating agent treats the desizing sewage containing 1-10 g/l PVA, wherein the COD (chemical oxygen demand) concentration of the desizing sewage reaches 5x104-10x104 mg/L, and chromaticity is 400 times; the removal rate reaches 80-85%, and recycle rate of PVA is 85-90%, and the chromaticity is 100 times below; the composite powder-shaped sewage treating agent is featured by wide adaptive temperature scale, good treatment effect, high recycle rate, and obvious decoloration.
Description
Technical field
The invention belongs to sewage-treating agent and preparation method thereof, particularly belong to for PVA desized wastewater inorganic agent and
Preparation method.
Background technology
Desized wastewater is that produced waste water removed by the slurry carried by fabric with chemical agent, usually contains substantial amounts of
PVA (polyvinyl alcohol), the complicated components of this kind of waste water, and PVA, the COD concentration containing 1-10g/l reach 1 × 104-100×
104Mg/L, colourity reaches more than 400 times, owing to PVA is Non-ionic organic polymeric, common containing aluminium chlorhydroxide (PAC)
The electric charge that sewage-treating agent produces is difficult to adsorb it, and the clearance of COD can only achieve the response rate of 60-70%, PVA and can only reach
To 60-70%, do not reach the requirement of environmental protection and recovery.
Summary of the invention
The technical problem to be solved is to provide the clearance of a kind of COD and reaches the response rate of 80-85%, PVA
Reach the composite powder inorganic agent of 85-90%.
Another one technical problem to be solved by this invention is to provide the preparation side of above-mentioned composite powder sewage-treating agent
Method.
The present invention solves the technical scheme of technical problem: a kind of efficient composite powdery sewage disposal for desized wastewater
Agent, including following material and weight portion:
The particle diameter of above-mentioned various material is 80-400 mesh.
In order to increase the decoloring ability of sewage-treating agent, it is also possible to add the weight ratio of activated carbon, activated carbon and calcium sulfate
For 10-20:60-70.
The preparation method of the present invention is: by tartaric acid and ursodesoxycholic acid mixing 50-120 minute, add 2-chlorine almond
Acid, mixes 50-120 minute, adds calcium sulfate, mixes 50-120 minute, adds magnesium carbonate, mixes 40-60 minute, then adds
Enter calcium carbonate mixing 40-60 minute, add ferric chloride, mix 40-60 minute, add calcium oxide mixing 40-60 minute,
Add Borax, mix 120-150 minute,.
The present invention, by controlling and change the order that the inorganic molecule material of different functional groups adds, sends out in recombination process
Condition that is raw and that do not react, reaches these components and keeps good fractions distribution and stability thereof before adding, after adding
There is form transformation quickly and efficiently condense flocculability.
The present invention compared with prior art, has the following characteristics that
1, high efficiency energy potion multiple-effect, has the multiple medicines such as flocculant, corrosion inhibiter, antibacterial concurrently the most simultaneously
Effect of agent, the advantage integrating numerous water treatment product, coagulation performance is more excellent, and alumen ustum is big and tight, the dirt of removal
Mud densification volume is little and sedimentation velocity is fast.There is multiple efficacies such as significantly decolouring, degerming.
2, the material used by environmental protection is natural organic acid and inorganic mineral, inorganic chemical composition,
So product is nontoxic, non-secondary pollution.
3, powder, Composite, it is simple to produce and production process is pollution-free, product packaging is simple and is readily transported, comprehensively
Low cost.
4, under conditions of 20-50 DEG C, the PVA containing 1-10g/l that the present invention processes, COD concentration reaches 5 × 104-10
×104Mg/L, the desizing sewage of colourity 400 times, its clearance reaches the response rate of 80-85%, PVA and reaches 85-90%, colourity
Reaching less than 100 times, have adaptive temperature wide ranges, high treating effect, the response rate are high, obvious feature of decolouring.
