Abstract
The invention discloses a kind of recycling techniques of non-water soluble dye commercialization technique waste water, include the following steps: to wash through filter bag passes through ceramic membrane filter containing dyestuff and auxiliary agent waste water, remove the biggish suspended matter of partial size, the mixture containing dyestuff and auxiliary agent is concentrated to get using nanofiltration membrane, the mixture puts into sanding-pan as when being sanded, it reuses, the water after nanofiltration supplements water as technique and washing filter bag water is reused.Through technique of the present invention, effective concentration can achieve 2 ~ 5% after waste water from dyestuff concentration；And the useful component contained in waste water can be all of not generating new solid waste.
Description
Technical field
It is especially non-aqueous the present invention relates to a kind of recycling technique of the waste water generated in commercialization of dyes process
The recycling technique for the waste water that the commercialization of dyes process of dissolubility generates.
Background technique
Former dyestuff is subject to a certain number of fillers and auxiliary agent working process into commercial dye by mixing, grinding, makes
Dyestuff reaches standardized process and commercialization of dyes is claimed to process, such as Fig. 1.Commercialization of dyes processes the matter to stabilizing dye finished product
Amount, the application performance for promoting dyestuff and product quality are most important.To non-water soluble dye such as disperse dyes, reducing dye requirement
It can spread rapidly in water, become uniform and stable colloidal suspension, the average grain diameter of dye granule is in 1mm or so.It is sanded
Process is typically all to carry out in bead, some tiny glass powders are inevitably understood in sand grinding process and are generated, while also having portion
The grain fineness of requirement, while former Dyestuff synthesis and drying are not reached after dividing dyestuff to be sanded, the processes such as handling can also carry one secretly
A little mechanical admixtures etc., so having one of filtration system after sand milling, to remove bulky grain dyestuff and mechanical admixture.It is filtered
Filter bag needs periodic cleaning in journey, and cleaning process generates the waste water from dyestuff of the high COD of a large amount of high chromas.This kind of waste water a part can be with
It adds to inside sanding system, but bigger due to measuring, it is most of all using endless, pass through exhaustless part all
Biochemical system progress biochemical treatment is arrived again after adding flocculant sedimentation filtration.On the one hand the dyestuff and auxiliary agent of high added value are wasted,
In addition new solid waste is also created to need to handle.
Summary of the invention
The object of the present invention is to provide a kind of recycling techniques of non-water soluble dye commercialization technique waste water, reach dye
Material and auxiliary agent and water reuse, have the advantages that the combination of economy and environmental benefit.
Realizing the technical solution of the object of the invention is: a kind of recycling benefit of non-water soluble dye commercialization technique waste water
With technique, include the following steps: to wash through filter bag passes through ceramic membrane filter containing dyestuff and auxiliary agent waste water, removes biggish suspension
Object is concentrated to get the mixture containing dyestuff and auxiliary agent using nanofiltration membrane, which puts into sanding-pan as when being sanded,
It reuses, the water after nanofiltration supplements water as technique and washing filter bag water is reused.
In above-mentioned steps, the effective concentration containing dyestuff and auxiliary agent waste water be 0.005% ~ 1%(effective concentration refer to containing auxiliary agent and
The sum of dye component), invalid components are that 0.05%(refers to ash content and tiny sand milling pearl etc inorganic constituents).
In above-mentioned steps, the aperture of ceramic membrane is 5 microns.
In above-mentioned steps, the aperture of nanofiltration membrane is 0.5 micron.
In above-mentioned steps, the volume after nanofiltration membrane nanofiltration concentration is 2 ~ 1000 times before nanofiltration.
Compared with prior art, the invention has the advantages that effective concentration can achieve 2 ~ 5% after the concentration of (1) waste water from dyestuff.
(2) useful component contained in waste water can be all of.(3) new solid waste is not generated.
Detailed description of the invention
Fig. 1 is the process flow diagram of prior art.
Fig. 2 is the flow diagram of technique of the present invention.
Specific embodiment
The present invention is further elaborated with reference to the accompanying drawings and examples.
Such as Fig. 2, the recycling technique of technique waste water is commercialized in non-water soluble dye of the present invention, including walks as follows
It is rapid: to pass through ceramic membrane filter containing dyestuff and auxiliary agent waste water through filter bag washing, remove biggish suspended matter, using nanofiltration membrane mistake
Filter is concentrated to get the mixture containing dyestuff and auxiliary agent, and the mixture is smaller due to measuring after nanofiltration membrane is concentrated, and can be used as
Sanding-pan is put into when sand milling, is reused, and the water after nanofiltration is the clear water without dyestuff and auxiliary agent, can be used as technique supplement water
And washing filter bag water is reused.
Embodiment 1: collecting filter wash bag waste water 500KG in disperse blue 60 commodity process, and detection effective component is
0.23%, invalid components 0.10% are collected into water 444KG by ceramic membrane after nanofiltration membrane, 2.28% high concentration containing effective component
500 grams of invalid components, 5KG moisture is lost in dyestuff and auxiliary agent 50.5KG in operating process.
Embodiment 2: collecting filter wash bag waste water 500KG in reduced olive T commodity process, and detection effective component is
0.41%, invalid components 0.15% are collected into water 394KG by ceramic membrane after nanofiltration membrane, 2.09% high concentration containing effective component
750 grams of invalid components, 5.25KG moisture is lost in dyestuff and auxiliary agent 98KG in operating process.
