Abstract
The present invention relates to a scale inhibitor for water containing barium and strontium. The inhibitor is prepared by mixing 10 parts by weight of 1-hydoxy ethyidene-1.1-diphosphonic acid, 10 parts by weight of polyacrylic acid, 10 parts by weight of ammonium citrate, 25 parts by weight of 2-phosphonobutane -1,2,4-tricarboxylic acid and 45 parts by weight of pure water into chemicals of organophosphate and polymer. The scale inhibitor has low cost and favorable scale inhibition to hard water and water containing barium and strontium and has high iron-ion solubility. The scale inhibitor does not result in secondary pollution to a membrane system and can simultaneously realize effective scale inhibition and favorable corrosion inhibition.
Description
Technical field
The present invention relates to a kind of dirt dispersion agent that prevents the film scaling for the embrane method water treatment, specifically a kind of water antisludging agent be used to containing barium, strontium.
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 increasingly outstanding, 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 film scaling wherein; The rear end precision processing of waste water recycling process generally adopts film to process, and such 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; Dirty stifled main source is that the ion in the water loses due to the settling after concentrating through membrane element.Solution to the problems described above has; Ion-exchange, adjusting water inlet PH, adding Scale inhibitors; Yet only have the Scale inhibitors of interpolation and ion-exchange to deal with problems for unconventional ion barium, strontium, iron; And Scale inhibitors commonly used removal effect for barium, strontium, iron is arranged is not very desirable, and exist that chemical feeding quantity is large, take off steady shortcoming under the polluted membrane element, reconcentration condition; Iron ion has oxygenizement to make it lose effect for the resin of ion-exchange.
Summary of the invention
For above defective, the invention provides the water antisludging agent that a kind of cost is lower, effective to high rigidity and baric, strontium water resistance dirt, can not cause secondary pollution to the film system, thereby can be in effective scale inhibition and reach the purpose of good corrosion mitigating effect, have very high iron ion tolerance.
For achieving the above object, the present invention is by the following technical solutions:
A kind of water antisludging agent be used to containing barium, strontium, its preparation is by hydroxy ethylene diphosphonic acid, polyacrylic acid, ammonium citrate, 2 phosphonate groups-1,2, the organophosphate that 4-butane tricarboxylate and pure water are mixed and polymer chemistry material, described hydroxy ethylene diphosphonic acid proportioning weight part is 10%, described polyacrylic acid weight part is 10%, described ammonium citrate proportioning weight part is 10%, described 2 phosphonate groups-1, the pure water of 2,4-butane tricarboxylate weight part 25%, above-mentioned batching and 45% weight part is mixed.
The beneficial effect of the water antisludging agent be used to containing barium, strontium of the present invention is: cost is lower, effective to high rigidity and baric, strontium water resistance dirt, can not cause secondary pollution to the film system; Can be in effective scale inhibition and reach the purpose of good corrosion mitigating effect, have very high iron ion content.
