Description
Technical field
The present invention relates to a kind of composite water disposal agent, belong to water-treatment technology field.
Background technology
Water is human being's production and the indispensable natural resources of life, is also the environmental resources that biology is depended on for existence, and along with the aggravation of water resources crisis and quality of water environment constantly worsen, shortage of water resources has developed into one of resources and environment problems that the world receives much attention.Therefore, water saving, to administer sewage, mining new source of water very important, and greatly develop water treatment method and will play vital effect for this technical problem of solution shortage of water resources.
The method of water treatment has a lot, but existing water treatment method has physical treatment process, method of chemical treatment and biological treatment.Physical treatment process is the simplest water treating method, and it reclaims the undissolved suspended contaminant in sewage by physical sepn effect, and physical treatment process can only process some simple wastewater treatments, but process is very incomplete, is difficult to reach emission standard; Biological treatment is the pollutant dissolution made by microbial metabolism in sewage, but the method investment is large, and running cost is high.Therefore, chemical treatment method is more satisfactory method.Chemical treatment method is with water conditioner process pollutent, wherein water conditioner Main Function be control incrustation scale and mud formation, reduce foam, reduce contact with water material corrosion, except suspended solids and toxic substance, the deodorization and discoloration in anhydrating, soften and stabilizing water quality etc.Therefore water conditioner comprises flocculation agent, flocculation agent, inhibiter, Scale inhibitors, sterilant, dispersion agent, clean-out system, prefilming agent, defoamer, discoloring agent, sequestrant, oxygen scavenger and ion exchange resin etc.
Chinese patent literature discloses the water conditioner that a kind of name is called " a kind of sewage-treating agent " (publication number: CN104030377 A, publication date: on 09 10th, 2014).It is by sodium phosphate 20 ~ 40 parts, ethylene diamine tetra methylene phosphonic acid 10 ~ 15 parts, sodium phosphate 10 ~ 20 parts, tripoly phosphate sodium STPP 4 ~ 8 parts, Silver Nitrate 2 ~ 4 parts, and sodium polyacrylate 4 ~ 8 parts is made.Although it effectively can remove the pollutent in water, cost is low, can reach the standard of discharge, and the compound containing phosphorus due to it is more, easily makes body eutrophication, promotes bacterium algae propagation and forms public hazards such as " red tides ".And for example Chinese patent literature discloses the water conditioner that a kind of name is called " composite water disposal agent " (publication number: CN103663738 A, publication date: on 03 26th, 2014).It is by sodium wolframate 15 ~ 45 parts; Poly aspartic acid 5 ~ 25 parts; Zinc salt 1 ~ 5 part; Sodium Benzoate 2 ~ 15 parts; Carboxylate salt 2 ~ 25 parts is made.Sodium wolframate is as its inhibiter, and functional and low toxicity, but cost is high, consumption is bigger than normal.How reducing costs, strengthening usefulness will be research direction from now on.Therefore, in order to solve the technical problem that above-mentioned water conditioner exists, develop a kind of newly, the water conditioner of environmental protection is very important to water resources protection.
Summary of the invention
For above-mentioned the deficiencies in the prior art, technical problem to be solved by this invention proposes the low and composite water disposal agent that decontamination effect improving is good of a kind of environmental protection, cost.
The present invention for the taked technical scheme that solves the problem is:
A kind of composite water disposal agent, is made up of each component of following weight: polyacrylamide 1 ~ 5 part, aluminium iron polychloride 10 ~ 20 parts, starch 10 ~ 20 parts, sodium lignosulfonate 2 ~ 8 parts, poly aspartic acid 3 ~ 9 parts, alkyl epoxy carboxylic acid sodium 2 ~ 8 parts, sodium alginate 1 ~ 5 part, Trisodium Citrate 2 ~ 6 parts, 1 ~ 5 part, zinc sulfate, water glass 10 ~ 15 parts, 1 ~ 3 part, phosphorus lime, clorox 1 ~ 7 part.
Its weight is as follows:
Polyacrylamide 3 parts, aluminium iron polychloride 15 parts, starch 15 parts, sodium lignosulfonate 5 parts, poly aspartic acid 6 parts, alkyl epoxy carboxylic acid sodium 5 parts, sodium alginate 3 parts, Trisodium Citrate 4 parts, 3 parts, zinc sulfate, water glass 13 parts, 2 parts, phosphorus lime, clorox 4 parts.
In the present invention, aluminium iron polychloride is a kind of inorganic composite flocculant; Polyacrylamide, is a kind of Syn-Organic flocculants, belongs to flocculant in non-ion type.By the removing of inorganic flocculating agent or reduce turbidity or suspended substance in water, the effect of quickening impurities in water and sludge settling speed and the charge neutralization of organic floculant, adsorption bridging effect combine, make water conditioner increase flocculating effect, improve clean level.In addition, starch, is a kind of natural organic high-molecular modified flocculant, originates abundanter, greatly lower the cost of water conditioner.
Because sodium lignosulfonate itself is containing functional groups such as hydroxyl, carboxyl, carbonyls, therefore, sodium lignosulfonate has certain dispersion, bonding, chelating ability, in water treatment, can be used as flocculation agent, rust-preventive agent, dispersion agent, ion exchange resin etc., water purifying effect can be improved further.
Poly aspartic acid, has excellent scale inhibition and dispersion performance and good biodegradability, is the green polymer and water conditioner of generally acknowledging at present.Alkyl epoxy carboxylic acid sodium is nontoxic, energy chlorine-resistant, heatproof, very excellent to the scale inhibition effect of calcium carbonate.When composite with zinc salt, in addition there is corrosion inhibition.Poly aspartic acid and alkyl epoxy carboxylic acid sodium have good Concord Action, greatly enhance the scale-inhibiting properties of water conditioner.
The linear macromolecule structure of sodium alginate can pass moisture film, by contained functional group, and adsorption bridging between particle and particle.By sodium alginate and aluminium iron polychloride composite, good flocculation treatment effect can be obtained.
Trisodium Citrate, zinc sulfate, water glass is good inhibiter.Compare with sodium wolframate, these compounds are inexpensive, nontoxic, and corrosion mitigating effect is pretty good.Although water glass can generate silicon dirt, sodium lignosulfonate and Trisodium Citrate dispersible these silicon dirts, thus improve the corrosion inhibition of water conditioner.
Phosphorus lime is as the auxiliary of water conditioner, and it can remove Pb in the aqueous solution
2+the heavy metal ion such as ion, reduce the content of heavy metal, improve Water warfare grade.
Clorox plays the effect of biocide in water conditioner.Its consumption is few, lasting medicine, and do not work with the ammonia in water and most of amine, sterilization effect does not affect by pH value, very appropriate alkaline water treatment system.
The invention has the beneficial effects as follows:
The present invention takes full advantage of flocculation agent, the Scale inhibitors of water conditioner, inhibiter, and the synergy of auxiliary and biocide improves the function of water conditioner, thus improves water purifying effect.Also use the dissemination of the throwing out of starch, sodium lignosulfonate and Trisodium Citrate simultaneously, reduce the cost of flocculation agent and inhibiter, thus reduce the cost of water conditioner.In addition, the material not containing phosphorus in water conditioner, avoids body eutrophication.Therefore, water conditioner environmental protection provided by the present invention, cost are low and decontamination effect improving good, can be applicable to the water treatment of waste water, sewage etc.
