Abstract
The invention relates to a high-hardness water-quality scale inhibition agent comprising organophosphate and a polymeric chemical substance, wherein the organophosphate is prepared by mixing the following components in percentage by weight: 10 percent of hydroxyethylidene diphosphonic acid, 10 percent of polyacrylic acid, 40 percent of citric acid and 40 percent of pure water. On the basis that the traditional scale inhibition and dispersion agent has chelating performance and complexation performance and by the configuration of new materials, the high-hardness water-quality scale inhibition agent increases a function of a PH-regulating scale inhibition method, has lower cost, scale inhibition and good cleaning effect at the same time, especially has better scale inhibition effect for high-hardness water and can not cause secondary pollution to a film system.
Description
Technical field
The present invention relates to a kind of dispersion agent that prevents the fouling of film system that is used for the embrane method water treatment, specifically a kind of high-hardness water scale inhibitor.
Background technology
Under the situation that is on the rise of development that present economy is advanced by leaps and bounds and environmental pollution, lack of water phenomenon and water quality deterioration problem are outstanding day by day, so the task of water treatment seems and becomes more and more important.Along with the continuous propelling of water technology, reverse osmosis membrane, nanofiltration membrane, ultra-filtration membrane are popularized gradually in the application in clean water treatment, reusing sewage field, are exactly one of most important medicament wherein for the dirt dispersion agent that prevents the fouling of film system wherein.The rear end precision processing of waste water recycling process generally adopts film to handle, and as ultra-filtration membrane, nanofiltration membrane, reverse osmosis membrane etc., the dirt of film system is stifled to be the biggest obstacle of its normal operation; The hardness of waste water is higher, and corresponding calcium magnesium is also corresponding higher, and the calcium magnesium scale is one of dirty stifled the biggest factor of film system, has therefore controlled the calcium magnesium scale and has also just controlled the dirty stifled greatest problem of film.The method of control calcium magnesium scale mainly contains: the ion exchange softening method, add acid and transfer the PH method, add method such as dirt dispersion agent; Ion exchange softening method wherein generally adopts the calcium magnesium in the sodium type sun resins exchange water, and its hardness is reduced, and after resin is saturated, regenerates with Industrial Salt, and the calcium magnesium in the resin is flowed out with regenerated liquid.The shortcoming of this method is to need to drop into bigger switching equipment, and periodic replacement aged resin, and cost is higher, has wasted great amount of water resources during regeneration; Add acid and transfer the PH method only to the good effect that has with carbonate bonded calcium magnesium scale, but to sulfate radical, fluoridize root bonded calcium magnesium scale and colloid dirt etc. and have little effect; Add the dirt dispersion agent method and utilize its good chelating, complex performance,, metallic pollution dirty stifled to colloid, Organic pollutants have good prevention effect; The main raw material of dirt dispersion agent is organophosphate, phosphoric acid ester, polymkeric substance etc. at present, in the high-hardness water of waste water recycling, generally adopts the amount of dirt dispersion agent bigger, and the organic composition of dirt dispersion agent itself is to the secondary pollution of film system.
Summary of the invention
At above defective, the invention provides a kind of cost lower, good to the high hardness water scale inhibition effect, can not cause the high-hardness water scale inhibitor of secondary pollution to the film system, thereby can be in effective scale inhibition and reach the purpose of good cleaning performance.
For achieving the above object, the present invention is by the following technical solutions:
A kind of high-hardness water scale inhibitor, its preparation comprises by hydroxy ethylene diphosphonic acid, polyacrylic acid, citric acid and pure water and is mixed and made into organophosphate and polymer chemistry material, and described hydroxy ethylene diphosphonic acid proportioning weight part is 10%, described polyacrylic acid weight part is 10%, described citric acid proportioning weight part is 40%, above-mentioned batching is mixed with the pure water of 40% weight part.
The beneficial effect of high-hardness water scale inhibitor of the present invention is: the configuration by type material makes it have on the basis of chelating, complex performance at traditional dirt dispersion agent, has increased to transfer the function of PH scale inhibition method, and has had cheap cost; In scale inhibition, have excellent cleaning effect again, especially better to the high hardness water scale inhibition effect; Cost is lower, can not cause secondary pollution to the film system.

Embodiment 2
The described high-hardness water scale inhibitor of the embodiment of the invention comprises by hydroxy ethylene diphosphonic acid, polyacrylic acid, citric acid and pure water being mixed and made into organophosphate and polymer chemistry material that described hydroxy ethylene diphosphonic acid proportioning weight part is 12%; Described polyacrylic acid weight part is 9%, and described citric acid proportioning weight part is 42%, and above-mentioned mix mixes with 37% pure water.
Embodiment 3
The described high-hardness water scale inhibitor of the embodiment of the invention comprises by hydroxy ethylene diphosphonic acid, polyacrylic acid, citric acid and pure water being mixed and made into organophosphate and polymer chemistry material that described hydroxy ethylene diphosphonic acid proportioning weight part is 9%; Described polyacrylic acid weight part is 11%, and described citric acid proportioning weight part is 39%, and above-mentioned mix mixes with 41% pure water.
More than show and described principal character of the present invention, ultimate principle; but above-described embodiment; the present invention embodiment a kind of more preferably just; under the prerequisite that does not break away from core texture and invention spirit; the present invention also has changes and improvements, so common variation and replacement that those skilled in the art carries out in the technical solution of the present invention scope all should be included in protection scope of the present invention.
