Abstract
The invention relates to a high-hardness water scale inhibitor, and the preparation comprises the following steps of mixing hexamethylene diamine tetramethylene phosphoric acid, 2-hydroxy phosphorus acetic acid, polyamino polyether methylene phosphonic acid and pure water for preparing an organic phosphate and a polymer chemical substance, wherein the weight percent of the hexamethylene diamine tetramethylene phosphoric acid is 10%, the weight percent of the 2-hydroxy phosphorus acetic acid is 20%, the weight percent of the polyamino polyether methylene phosphonic acid is 20%, and the components are mixed with 50% by weight of pure water. The high-hardness water scale inhibitor has the beneficial effects that the configuration of novel materials leads the high-hardness water scale inhibitor to increase the functions of specially complexing dispersed iron and silicon salt and retarding corrosion on the basis of having the chelating and the complexing performances of the traditional signal scale inhibitor and dispersant; furthermore, the high-hardness water scale inhibitor has low cost and can not cause the secondary pollution to a membrane 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 development that present economy is advanced by leaps and bounds and environmental pollution are on the rise, 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.Iron compound in the water all can cause expendable pollution to the present conventional membrane element that uses, and the influence of control iron ion in water becomes a difficult problem, yet control iron ion method mainly contains: ion-exchange, add flocculation agent, add method such as dirt dispersion agent; Ion exchange softening method wherein generally adopts the iron in the sodium type sun resins exchange water, and its concentration degree is reduced, and after resin is saturated, regenerates with Industrial Salt, and the iron ion 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, and iron also has irreversible destruction for resin in addition; Add the flocculation agent method to having good effect with iron ion, but be easy to make flocculation agent to enter the film system if any operational issue; Add the dirt dispersion agent method and utilize its good chelating and complex performance, dirt is blocked up to colloid, calcium magnesium pollutes, Organic pollutants reach good prevention effect; The main raw material of dirt dispersion agent is organophosphate, phosphoric acid ester, polymkeric substance etc. at present, in containing the water quality of a large amount of iron ions, generally adopts the amount of dirt dispersion agent bigger, and the organic composition of dirt dispersion agent itself pollutes the film secondary system.
Summary of the invention
At above defective, the present invention is lower, good to high iron-bearing water scale inhibition effect for a kind of cost, 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 corrosion mitigating effect.
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 hexamethylene-diamine tetramethylene phosphoric acid, 2-hydroxyl phosphorus guanidine-acetic acid, polyamino polyether methylene phosphoric acid and pure water and is mixed and made into organophosphate and polymer chemistry material, described hexamethylene-diamine tetramethylene phosphorylated ligand weight/power ratio part is 10%, described 2-hydroxyl phosphorus guanidine-acetic acid weight part is 20%, described polyamino polyether methylene phosphorylated ligand weight/power ratio part is 20%, and above-mentioned batching is mixed with the pure water of 50% 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 the single dirt dispersion agent of tradition, has increased the function that special complexing disperses iron and silicon salt and inhibition; Cost is lower, can not cause secondary pollution to the film system.
