Abstract
The invention relates to a method of treating printing and dyeing wastewater through flocculation oxidation, which comprises the following steps: adding a Co (III) phosphate coordination compound and an oxidizing agent into the printing and dyeing wastewater, stirring, decoloring, static settlement or settling to obtain the treated printing and dyeing wastewater. According to the method, disclosed by the invention, the adding and reaction sequences of various reagents are not needed to consider; the method can be realized through conventional equipment and devices, and special modification is not needed for the equipment; the method can be carried out on natural conditions without illumination.
Description
Technical field
The invention belongs to the method for wastewater treatment field, particularly a kind of method of flocculation oxidation treatment of dyeing and printing.
Background technology
Development along with dyestuffs industries, its problem of environmental pollution brought also becomes increasingly conspicuous, these motley fine chemicals, when bringing our visual enjoyment, also become the source of pollution of welding at a large amount of coloured sewage of the industries such as DYE PRODUCTION, textile printing and dyeing, paper pulp, papermaking generation.
The removal that great environmental problem is exactly colourity that waste water containing dye faces, even because the dyestuff in water body affects the normal function of receiving water body, hinder the purification voluntarily of water body, to water microorganisms and also toxic effect of fish; Simultaneously, the dyestuff in water body has weakened the transmission of sunlight in water, suppresses the photosynthesis of waterplant in water body, affects the growth that it is grown also and then has influence on human consumers at different levels, and the diversity of whole aquatic ecosystem is descended.In addition, dyestuff, as the stable organic compound of a class formation, has long residence time in environment, human health and growth and development of plants and animals are had to potential harm.
With regard to the improvement of waste water from dyestuff, decolouring is the problem that at first will solve.Dyestuff and printing and dyeing industrial waste water kind are many, composition is complicated, and different water quality need be processed with diverse ways.The oxidative decoloration method is by means of redox reaction, to destroy conjugated structure or the chromophoric group of dyestuff, the organism in waste water can be become to carbonic acid gas, water and oxynitride etc. simultaneously.In the decolouring of dyestuff was processed, the superoxide such as hydrogen peroxide were the oxygenants often used, but while using separately oxidation capacity a little less than, oxidation rate is slow, and the mineralising poor effect.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method of flocculation oxidation treatment of dyeing and printing, and the method is without considering adding and reaction sequence of all ingredients; This invention gets final product with conventional equipment and device, without equipment is carried out to special transformation; This invention, without illumination, can be carried out under natural condition.
The method of a kind of flocculation oxidation treatment of dyeing and printing of the present invention comprises:
In dyeing waste water, add respectively cobalt (III) phosphate complex flocculation oxidation catalyzer and oxygenant, the stirring processing of decolouring, staticly settle or sedimentation, dyeing waste water after being processed, wherein the volume ratio of dyeing waste water and oxygenant is 4～8:1, and the proportioning of cobalt (III) phosphate complex and dyeing waste water is 1.0～20g:1L.
Described cobalt (III) phosphate complex is that phosphoric acid six cobaltammines (III), tricresyl phosphate (quadrol) close one or both in cobalt (III).
Described oxygenant is one or more in hydrogen peroxide, hydrogen persulfate aqueous solutions of potassium, peroxide acetate aqueous solution.
The mass percent concentration of described oxygenant is 0.9%-9%.
Described churning time is 10-60min.
Described precipitation or settling time are 20-60min.
The preparation method of cobalt (III) phosphate complex:
Prepare respectively trivalent cobalt complex and aqueous phosphatic, then the trivalent cobalt complex aqueous solution and aqueous phosphatic are mixed to (trivalent cobalt complex and phosphatic mol ratio are 1:1-1.5), under 20-50 ℃ of condition, stir 10-30min, be precipitated, filter, obtain cobalt (III) phosphate complex.
The technique that the present invention has avoided traditional first flocculation to reoxidize, the cobalt adopted (III) phosphate complex has flocculation agent and oxide catalyst concurrently, oxidizing reaction and flocculation reaction can occur simultaneously after adding cobalt (III) phosphate complex, and has a synergetic property, can the Quick Oxidation disperse dyes, can reach high oxidation efficiency, make the dyestuff permineralization, in the processing of dyeing and finishing wastewater, have application prospect preferably.
Beneficial effect
(1) at first prepared cobalt (III) phosphate complex of the present invention is a kind of effective flocculation agent, can make most anionic dyestuff flocculations, integrates decolouring, flocculation, removes COD, and the treatment time is short, and percent of decolourization is high, and the COD clearance is high;
(2) prepared cobalt (III) phosphate complex of the present invention is again a kind of effective oxide catalyst, but the quick catalysis superoxide produces the strong oxidizing property free radical, makes it and dyestuff generation redox reaction, and speed of reaction is fast, and percent of decolourization is high;
(3) the present invention is without considering adding and reaction sequence of all ingredients;
(4) the present invention uses conventional equipment and device to get final product, without equipment is carried out to special transformation; The present invention, without illumination, can carry out under natural condition.
