Abstract
The present invention relates to water-treatment technology fields, particularly disclose a kind of environmentally protective medicament for recirculated water zero blowdown.This is used for the environmentally protective medicament of recirculated water zero blowdown, it is characterized in that, add water to be mixed according to certain weight proportion by antisludging agent, corrosion inhibiter, dispersant, surfactant and fluorescent tracer.The present invention not only solves sewage handling problem, but also meets industrial recirculated water demand, and water consumption is greatly saved；Selected raw material is environmentally friendly without phosphorus raw material, is not easy that microorganism, especially algae is caused to overgrow in sewage, and has certain bactericidal effect.
Description
（One）Technical field
The present invention relates to water-treatment technology fields, more particularly to a kind of environmentally protective medicament for recirculated water zero blowdown.
（Two）Background technology
With China's industrialization, urbanization, intensive agriculture fast development, it is multiple to generate large amount of sewage, especially ingredient
If miscellaneous sewage brings tremendous influence without processing direct emission to water resource environment.These sewage are by simple place
Reason, it is the significant problem for solving water resources problems to be back to industrial circulating cooling water.
Due to containing a large amount of inorganic ions in waste water（Such as Ca2-、Mg2-、SO4 2-、Cl-）And organic matter, as system is transported
Row, cycles of concentration are got higher, and system equipment surface is readily formed indissoluble salt, makes equipment scaling and vertical view, is influencing system just
Often operation.The patent report that corrosion inhibiting and descaling agent is added in recirculated cooling water is less.The invention of the patent No. 201410559323.4
A kind of power plant effluent fully recovering is disclosed in patent in the anti-incrustation corrosion inhibitor of recirculated water, has that safety is safe and reliable, is easy to
The features such as configuring, is easy to use, still, the water treatment product accommodation is relatively narrow, only effective to power plant effluent；And it is formulated
In contain phosphorus, in the sewage containing organic matter be easier grow biotinylated biomolecule growth, increase foundry loam attachment probability.
（Three）Invention content
In order to compensate for the shortcomings of the prior art, the present invention provides one kind to have a wide range of application, preparation is simply to recycle
The environmentally protective medicament of water zero blowdown.
The present invention is achieved through the following technical solutions：
A kind of environmentally protective medicament for recirculated water zero blowdown adds water to be mixed by the raw material of following parts by weight：
20-35 parts of antisludging agent, 15-30 parts of corrosion inhibiter, 10-15 parts of dispersant, 0.5-1 parts of surfactant, fluorescent tracing
0.5-1 parts of agent, water surplus amount to 100 parts.
The weight proportion of its preferred each raw material is：
27-32 parts of antisludging agent, 20-28 parts of corrosion inhibiter, 12-15 parts of dispersant, 0.5-0.8 parts of surfactant, fluorescence show
0.5-0.7 parts of track agent, water surplus amount to 100 parts.
The antisludging agent is chitosan-hyperbranched poly acrylamide grafted copolymer or carboxymethyl chitosan.
The corrosion inhibiter is one or both of cinnamic acid, furfural and vanillic aldehyde.
The dispersant is sulfamic acid.
The surfactant is Sodium Sulfo-succinate or fatty alcohol polyoxyethylene ether.
The fluorescent tracer is 1,3,6,8- pyrene sodium salts, and adding consistency is controlled by fluorescent tracer.
Main component chitosan-hyperbranched poly acrylamide grafted copolymer of the present invention, according to free radical polymerization principle,
Using redox initiation system, structurally-modified auxiliary agent N,N methylene bis acrylamide (MBA) and methacrylic sulfonic acid are introduced
Sodium (SMAS) carries out acrylamide monomer (AM), MethacryloyloxyethylTrimethyl Trimethyl Ammonium Chloride (DMC), acrylic acid (AA)
Aqueous free radical copolymerization prepares a series of branched hyperbranched poly acrylamide of different molecular weights, then again
Itself and chitosan graft are copolymerized, finally obtain chitosan-hyperbranched poly acrylamide grafted copolymer, it has hyperbranched polymerization
Feature more than object active group can efficiently chelate ion, while introduce chitosan, both increase molecular weight, and
And there is certain bactericidal effect.
Beneficial effects of the present invention are：
（1）The effect of medicament through the invention can realize waste water recycling in recirculated water, and run intermediate not outer one drop of row
Sewage really realizes zero blowdown；
（2）Not only it solves sewage handling problem, but also meets industrial recirculated water demand, be greatly saved and use water
Amount；
（3）Selected raw material is environmentally friendly without phosphorus raw material, is not easy to cause microorganism, especially algae is in sewage
Overgrowing, and there is certain bactericidal effect；
（4）Have a wide range of application, the wastewater application of different leech can be realized in circulation.
