Abstract

The invention relates to a scale inhibitor for reverse osmosis of concentrated water of printing and dyeing industry and a preparation method thereof. Along with the high-speed development of economy and society of China, the living standards of people are greatly improved and increased. Whereas, we should have a sight of that many problems exist in the development of economy of our country at the same time, for example, the environmental pollution is severe. At present, environmental pollution of our country has already been extended to various aspects such as atmosphere, water and soil, the pollution of each aspect is unoptimistic, and the water pollution is most outstanding. Industries which may cause huge pollution to the water include chemical industry, printing, smelting, mineral products, paper making textile and the like. Sewage generated from the printing and dyeing industry contains a large number of contaminants and can cause serious pollution to environment water. The scale inhibitor for the reverse osmosis of the concentrated water of the printing and dyeing industry is prepared through combining styrene sulfonic acid (SSS), polyepoxysuccinic acid (PESA), polyaspartic acid (PASP) and 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), wherein the mass ratio of SSS to PESA to PASP to PBTC is (30 to 50): (15 to 25): (20 to 30): (5 to 10).

Description

A kind of antisludging agent for the dense water counter-infiltration of dyeing and preparation method thereof
Technical field
The present invention relates to the antisludging agent of the dense water counter-infiltration of dyeing.
Background technology
Along with the increase of expanding economy and population, the mankind constantly increase the demand of water resource, add and exist waterUnreasonable exploitation and the utilization of resource, there is water shortage problem in various degree in a lot of countries and regions, this phenomenon is called water moneySource shortage.
It is also the major reason that causes shortage of water resources that water pollutes, and textile printing and dyeing wastewater is owing to having large, the organic dirt of the water yieldDye the features such as thing content is high, alkalescence is large, change of water quality is large, belong to difficult, endanger one of strong industrial wastewater, the tribute that water is pollutedOffer quite large. Thereby treatment of dyeing wastewater plays considerable left and right in overall water pollution control.
Dense water counter-infiltration is a kind of important method for the treatment of of dyeing wastewater, and dense water counter-infiltration requires ten for antisludging agentPoint high, the present invention is exactly the efficient scale inhibitor for this kind of water quality.
Summary of the invention
Invention, for the problem and shortage of above-mentioned existence, provides the antisludging agent of the dense water counter-infiltration of a kind of dyeing
And preparation method thereof, dirt dispersion agent is by styrene sulfonic acid (SSS), poly-epoxy succinic acid (PESA), poly-aspartate(PASP), 2-phosphonic acids butane-1,2,4-tricarboxylic acids (PBTC) combination, the mass ratio of SSS, PESA, PASP, PBTC is 25～40:15～25:20～30:5～10; The invention provides the preparation side of the antisludging agent of the dense water counter-infiltration of a kind of dyeingMethod, puts into successively stirring and dissolving in stirred vessel by four kinds of materials according to certain mass ratio and gets final product to obtain product of the present invention. ThisAntisludging agent is hyperconcetration type liquid preparation, can infinite dilution use. In the present invention, four kinds of materials are pressed certain mass than composite use,Scale inhibition effect is obviously better than wherein any material and uses separately, can save the reagent cost of desalinization. In the present inventionThe antisludging agent of the dense water counter-infiltration of dyeing is stable in high rigidity, high alkalinity, the effect of high-temperature Water Under solution, to calcium carbonate,Calcium phosphate has good scale inhibition peptizaiton, has good dispersing iron oxide and stable zinc salt effect simultaneously, can extensively useIn fields such as cold water process, low-pressure boiler water treatment and reverse osmosis water processing.
The technical solution adopted in the present invention is as follows:
Antisludging agent of the dense water counter-infiltration of dyeing and preparation method thereof, antisludging agent is by styrene sulfonic acid (SSS), poly-epoxy succinicAcid (PESA), poly-aspartate (PASP), 2-phosphonic acids butane-1,2,4-tricarboxylic acids (PBTC) combination.
Described SSS, PESA, the mass ratio of PASP, PBTC are 25～40:15～25:20～30:5～10.
The invention provides the preparation method of the antisludging agent of the dense water counter-infiltration of a kind of dyeing, by SSS, PESA, PASP,Tetra-kinds of materials of PBTC are put into successively stirring and dissolving in stirred vessel according to certain mass ratio and are got final product to obtain product of the present invention. This resistanceDirt agent is hyperconcetration type liquid preparation, can infinite dilution use.
The present invention compared with prior art has the following advantages:
Antisludging agent of the present invention adopts SSS, PESA, PASP, tetra-kinds of materials of PBTC to drop into successively according to certain mass ratioGet final product to obtain product of the present invention to stirring and dissolving in stirred vessel. This antisludging agent is hyperconcetration type liquid preparation, can infinite dilution makeWith.
In the present invention, four kinds of materials are pressed certain mass than composite use, and scale inhibition effect is obviously better than wherein any materialUse, and the antisludging agent use amount of the dense water counter-infiltration of the domestic existing dyeing of amount ratio separately will be lacked, and can save desalinizationReagent cost.
