Abstract
The invention discloses a preparation method of a hard-hardness high-iron and silicon water scale inhibitor and relates to the technical field of water treatment, in particular to a scale inhibitor for water treatment. The preparation method comprises the following steps of: firstly taking 17-19 mass parts of sodium hexametaphosphate, dissolving into pure water, agitating for 25-35 minutes till a solid is completely dissolved, adding pure water to dilute till 1000 mass parts are achieved; and then taking 3.5-4.5 mass parts of polyaspartic acid, adding into solution, agitating for 1.5-2.5 hours, adding 4-6 mass parts of hydroxy ethylidene diphosphate and 1.5-2.5 mass parts of zinc salt into the solution, agitating for 1.5-2.5 hours and standing for 3-5 hours to prepare the novel reverse osmosis membrane scale inhibitor. Through the preparation method, the problems existing in the existing scale inhibitor adopted in the water treatment that the water yield is reduced, the quality of produced water is reduced, the water inlet pressure boosts and the like are solved.
Description
Technical field
The present invention relates to water-treatment technology field, be specifically related to a kind of water treatment and use Scale inhibitors.
Background technology
Nowadays reverse osmosis system is usually seen in pure water process field right and wrong; Therefore the maintenance work of carrying out film is essential, but some enterprises often add the reverse osmosis membrane antisludging agent of single matter difference in order to practice thrift cost; Reverse osmosis membrane is caused great irreversible infringement; Descend like water production rate, produce water water quality and reduce intake pressure rising etc.
To above-mentioned defective, the present invention be to various medicaments carry out compound, the new formulation of developing has extraordinary dispersion sequestering action to calcium, magnesium, iron, silicon, through too much company is on probation, effect is very good.
Summary of the invention
The present invention provides the preparation method of the water antisludging agent of a kind of high firmness high ferro, silicon, the invention solves the water production rate that adopts existing Scale inhibitors to exist in the water treatment and descends, and produces water water quality and reduces problems such as intake pressure rising.
For addressing the above problem; The present invention adopts following technical scheme: the preparation method of the water antisludging agent of a kind of high firmness high ferro, silicon; At first get 17-19 mass fraction Sodium hexametaphosphate 99 and be dissolved in pure water, stir and dissolved fully to solid in 25-35 minute, be diluted to 1000 mass fractions adding pure water; Secondly; Getting 3.5-4.5 mass fraction SAP 73 adds in the solution; Stirred 1.5-2.5 hour; In solution, add 4-6 mass fraction hydroxy ethylidene-diphosphate and the stirring of 1.5-2.5 mass fraction zinc salt 1.5-2.5 hour again, leave standstill and be made into a kind of novel reverse osmosis membrane antisludging agent after 3-5 hour.
This Scale inhibitors is metals ions such as chelating complexing calcium, magnesium, silicon, iron, barium effectively, and clay particle, suspended substance etc. is had dissemination.
Because reverse osmosis system moves for a long time, materials such as various organism, metals ion, oxide compound, suspended substance can be deposited on the film surface in the former water, make film forming water production rate decline and produce the reduction of water water quality.The present invention is composite through using hydroxy ethylidene-diphosphate, SAP 73, Sodium hexametaphosphate 99 and zinc salt to carry out, and generates a kind of novel reverse osmosis antisludging agent.
The present invention is settling such as metals ion such as the calcium in the disperse water, magnesium, iron, silicon, barium and clay particle, suspended substance effectively, and can stop the formation of dirt.
Embodiment
With illustrated embodiments the present invention is done detailed explanation
below.
The preparation method of the water antisludging agent of a kind of high firmness high ferro, silicon at first gets the 18kg Sodium hexametaphosphate 99 and is dissolved in pure water, stirs to dissolve fully to solid in 30 minutes, is diluted to 1000kg adding pure water; Secondly, get the 4kg SAP 73 and add in the solution, stirred 2 hours, in solution, add 5kg hydroxy ethylidene-diphosphate and the stirring of 2kg zinc salt 2 hours again, leave standstill and be made into a kind of novel reverse osmosis membrane antisludging agent after 4 hours.
This Scale inhibitors is metals ions such as chelating complexing calcium, magnesium, silicon, iron, barium effectively, and clay particle, suspended substance etc. is had dissemination.
Method of use: before this Scale inhibitors is added in security personnel's strainer; In the dosing pump input channel, He Yuanshui gets into reverse osmosis system together, adds dose and mainly confirms according to water hardness: (hardness * 3)/200; Can draw the general dose that adds, take the circumstances into consideration increase and decrease according to system's particular case again.
Prove through experiment: adopt Scale inhibitors of the present invention and existing conventional Scale inhibitors to handle respectively; Handle metals ions such as calcium, magnesium, silicon, iron, barium in the water that back Scale inhibitors of the present invention handles than existing conventional Scale inhibitors, and decline 50-80% such as clay particle, suspended substance.
What should explain at last is: obviously, the foregoing description only be for clearly the present invention is described and is done for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among protection scope of the present invention.
Claims (1)
1. the preparation method of the water antisludging agent of a high firmness high ferro, silicon is characterized in that: at first get 17-19 mass fraction Sodium hexametaphosphate 99 and be dissolved in pure water, stir and dissolved fully to solid in 25-35 minute, be diluted to 1000 mass fractions adding pure water; Secondly; Getting 3.5-4.5 mass fraction SAP 73 adds in the solution; Stirred 1.5-2.5 hour; In solution, add 4-6 mass fraction hydroxy ethylidene-diphosphate and the stirring of 1.5-2.5 mass fraction zinc salt 1.5-2.5 hour again, leave standstill and be made into a kind of novel reverse osmosis membrane antisludging agent after 3-5 hour.
