Abstract
The invention provides a preparation method of a dyeing waste water treating agent, comprising the following steps: (1) mixing bentonite, corn starch and wheat starch uniformly, adding water and extruding into particles 1-2mm in diameter; (2) calcining the particles obtained in step (1) for 5-7h, cooling to room temperature; (3) mixing the calcined particles with an acrylamide solution and stirring; (4) adding an initiator into the mixture system to initiate polyreaction, then adding a cross-linking agent to initiate cross linking reaction to obtain a mixture; and (5) baking the mixture in step (4) to obtain the dyeing waste water treating agent. The dyeing waste water treating agent provided by the invention fully utilizes the expandability and absorbability of the bentonite, has strong absorption on chroma, phosphorus, heavy metal ions, organic matters and the like, and can be used as a purifying agent in waste water treatment.
Description
Technical field
The invention belongs to printing technology field, be specifically related to a kind for the treatment of of dyeing/printing wastewaters and preparation method thereof.
Background technology
Though dyestuff has very strong acute virus action unlike agricultural chemicals, people dye at azo dyes, anthraquinoneThe kind of finding tool mutagenicity and carcinogenesis in material, kiton colors, the catabolite of dyestuff mostly also is benzidineDeng some carcinogenic aromatic compounds. Dyestuff is as the stable organic compound of a class formation, have antiacid, alkali resistant,The characteristic such as anti-light, antimicrobial has longer demurrage in environment, and the dyestuff of extremely low concentration in water body, also can shadowRing the normal function of receiving water body, to aquatic microorganisms and also toxic effect of fish, make whole aquatic ecosystemDiversity declines. Therefore the negative effect of Dyes on Environment is not only its colourity and COD, but also is that it is rightThe potential hazard of human health and growth and development of plants and animals. Thereby waste water containing dye is China's main noxious industry at presentOne of waste water, is also the difficult point of sewage disposal, and dyestuff and treatment of dyeing wastewater are the important contents of Environmental Engineering research.
At present mainly contain adsorption bleaching, redox decolouring, coagulation decoloration processing etc. for the method for the treatment of of dyeing wastewater,Ion-exchange decolouring, milipore filter decolouring and biological decolouring technology are also carried out to certain research both at home and abroad. But, traditionCoagulation decoloration process waste water, resulting cost is higher, and is invalid to some special high-concentration printing and dyeing wastewaters etc.The too high operating costs such as oxidation-reduction method, ion-exchange, ultrafiltrationmembrane process also affected said method in practice shouldWith. Therefore, existing method is considered to have from economy, technical and usability for the various discoloration methods of dyeing waste waterCertain deficiency. Most of printworks still adopt charcoal absorption decolouring, but active carbon has selectively dyestuff, valencyLattice are higher, and regeneration difficulty, is restricted in the application aspect dyeing waste water adsorption bleaching, is generally only applied to concentration lowerTreatment of dyeing wastewater or advanced treating.
Therefore, need badly a kind of with low cost, treatment of dyeing/printing wastewaters that treatment effect is good is provided.
Summary of the invention
Goal of the invention: the treatment of dyeing/printing wastewaters that a kind for the treatment of effect is good is provided.
Technical scheme: the preparation method for the treatment of of dyeing/printing wastewaters, comprises the steps:

(2) particle obtaining in step (1) is placed under 500～600 DEG C of conditions and calcines 5～7h, be cooled to room temperature;
(3) particle after calcining is mixed with acrylamide solution, stir;
(4) in step (3) mixed system, add initator, initiated polymerization, then add crosslinking agent, cross-linking reaction,Obtain mixture;
(5) mixture in step (4) is dried, obtain treatment of dyeing/printing wastewaters.
Bentonite main component is montmorillonite, is a kind of function admirable, the clay that economic worth is higher, range of application is widerResource. Bentonite is as the important nonmetallic mineral of a class, through lot of domestic and foreign scholar's joint research for many years, moreMore demonstrate the feasibility of applying in field of Environment Protection. Research shows, bentonite, particularly modified product have higherIon exchangeable, larger dilatancy and adsorptivity preferably, to the colourity in water, phosphorus, heavy metal ion, haveMachine thing etc. all has stronger suction-operated, can be used as the cleanser of sewage disposal.
As preferably, in described acrylamide solution, the concentration of acrylamide is 10～50g/L.
As preferably, described stirring, whipping temp is 30～45 DEG C, mixing time is 2～5h.
As preferably, described initator is peroxidized t-butyl perbenzoate or cumyl peroxide.
As preferably, the addition of described initator is 5～8g/L.
As preferably, the reaction temperature of polymerisation is 45～65 DEG C, and the reaction time of polymerisation is 4～8h.
As preferably, described crosslinking agent is N hydroxymethyl acrylamide.
As preferably, the addition of described crosslinking agent is 1～3g/L.
As preferably, the reaction temperature of described cross-linking reaction is 35～55 DEG C, and the reaction time of cross-linking reaction is 2～6h.
The treatment of dyeing/printing wastewaters that the preparation method of above-mentioned treatment of dyeing/printing wastewaters prepares is in protection scope of the present inventionWithin.
Beneficial effect:
Treatment of dyeing/printing wastewaters prepared by the present invention has that preparation method is simple, high treating effect.
