Specific embodiment
Purpose, technical scheme and advantage for making the embodiment of the present invention are clearer, below will be in the embodiment of the present invention
Technical scheme be clearly and completely described.In embodiment, unreceipted actual conditions person, builds according to normal condition or manufacturer
The condition of view is carried out.Agents useful for same or the unreceipted production firm person of instrument, being can be by the commercially available conventional product bought and obtain
Product.
Below the embodiment of the present invention is specifically described for processing fabric of dyeing waste water and preparation method thereof.
A kind of fabric for processing dyeing waste water, it includes fabric body, and the area load of fabric body has tio2/g-
c3n4Layer.tio2Inexpensive, nontoxic, and photocatalysis speed is fast, non-selectivity, degraded completely, g-c3n4Because of its unique electronics knot
Structure, special stratiform pattern and suitable bandwidth, show good absorption characteristic to visible ray.So, preparation
tio2/g-c3n4Layer composite nano materials are composite photocatalyst material, by tio2And g-c3n4Load to fabric body surface not only
The visible light-responded scope of composite photocatalyst material can be expanded, and using the internal electric field effect that physics hetero-junctions is formed, realize light
Raw electronics and the sharp separation in hole, thus significantly improving the Photocatalytic Degradation Property of composite, and realize multiple pollutant
Photocatalysis fall, and the easy recycling of this catalysis material.Nanometer tio2/g-c3n4Layer had both widened tio2Spectrum
Response range is so as to have visible light catalysis activity；Meanwhile, in fabric body area load nanometer tio2/g-c3n4, increase
tio2/g-c3n4With the contact area of dyestuff, improve the efficiency for the treatment of of dyeing wastewater；It is easy to a nanometer tio2/g-c3n4Recovery
Recycle, it is to avoid Conventional nano powder body material is easily reunited, lead to the problem that photocatalytic activity reduces；Raw material is cheap, no dirty
Dye, preparation cost is low, can effective process dyeing waste water, simple to operate, economical and efficient.
Fabric body can be chosen as polyacrylonitril fabrics body, dacron body or bafta body.It is preferably provided with:
Polyacrylonitril fabrics body can be selected as fabric body, polyacrylonitrile is that a kind of heat stability is high, radiation resistance is good, power
Learn the strong synthetic fibers of performance, it is more widely applied, and material cost is relatively low.
It is preferably provided with: in every square metre of fabric body, uniform load has the tio that weight is 1.0g～20.0g2/g-c3n4Layer.
Control nanometer tio2/g-c3n4The thickness of layer, prevents due to nanometer tio2/g-c3n4Layer is blocked up and make tio2/g-c3n4Layer load is not
Stable, it is susceptible to come off and tio2/g-c3n4Layer reunion, excessively thin and reduce fabric body process dyeing waste water efficiency.More
Goodly, tio2/g-c3n4The weight of layer is 1.0g/m2～15.0g/m2, wherein, tio2And g-c3n4Mass ratio be 20～5:1,
Fabric body is the most obvious to the treatment effect of waste water.
It is preferably provided with: fabric body is formed using plain weave weaving, makes fabric body have certain stiffness and guarantor
Holding property, extends the service life of fabric body.
As the process chart of the preparation method that Fig. 1 is the above-mentioned fabric for processing dyeing waste water, first pass through presoma
Reaction obtains g-c3n4, remove the impurity on fabric body surface, by clean fabric body, acetic acid, ethanol, butyl titanate meanwhile
And g-c3n4In addition ultrasonic reactor, ultrasonic reaction obtains the fabric for processing dyeing waste water, and is carried out, is dried
Remain to use.
A kind of preparation method of the fabric for processing dyeing waste water, comprises the steps:
(1), remove the impurity on fabric body surface.The impurity avoiding fabric body surface is to tio2/g-c3n4The formation of layer
Impact and can not uniformly form tio2/g-c3n4Layer, also avoids tio2/g-c3n4The formation of layer is unstable, is susceptible to
Desorption.
Specifically, remove fabric body surface impurity can carry out as follows: by fabric body 60 DEG C～
At 80 DEG C, concentration is the na of 0.2mol/l～2mol/l2co3Clean 5min～30min in solution, then fabric body is existed successively
It is cleaned by ultrasonic 5min～15min in dehydrated alcohol and deionized water, be finally putting into baking oven and dry at 60 DEG C～120 DEG C.Use
na2co3Solution has good dissolubility, impurity and oil preparation can carry out dissolving quickly and chemical reaction occurs and is washed
Wash, then fabric body is cleaned by ultrasonic in dehydrated alcohol, remove impurity and the oil preparation on fabric body surface further, and
By the effect of supersonic vibration, so that the fine impurities on fabric body surface is removed, finally fabric body is entered in deionized water
Row is cleaned by ultrasonic, and makes the cleaning of fabric body more thorough.Fabric body is dried, it is to avoid the moisture shadow in fabric body
Ring follow-up tio2/g-c3n4The load of layer.Dried at 60 DEG C～120 DEG C, in the case that moisture evaporation is relatively fast,
Fabric body is avoided burning to occur or burns.
(2), by fabric body, butyl titanate, acetic acid and g-c3n4It is placed in ultrasonic reactor, add ethanol to adjust ultrasonic
The volume of the material in reactor accounts for the 60%～80% of ultrasonic reactor volume, it is to avoid the solution in ultrasonic reactor very few and
Damage instrument, excessively sputter at outside ultrasonic reactor, impact reaction.g-c3n4For solid, in order that g-c3n4Dispersion is more equal
Even, first fabric body is mixed with a part of ethanol, add butyl titanate, acetic acid, be subsequently adding g-c3n4It is made to divide in the solution
Dissipate uniformly, the convenient surface being supported on fabric body, finally in the material being adjusted by ethanol in ultrasonic reactor
Volume.
Ultrasonic reaction obtains the fabric for processing dyeing waste water, in ultrasonic reactor, provides reaction by ethanol
Environment is it is possible to suppress the hydrolysis of butyl titanate to a certain extent, it is to avoid what butyl titanate was too fast is hydrolyzed into tio2, its
In, the ratio of fabric body and ethanol is (1:2～10) g/ml, so that fabric body complete wetting, in ethanol solution, is beneficial to
tio2/g-c3n4Uniform load is on the surface of fabric body.It is preferably provided with: ethanol is dehydrated alcohol.More preferably: butyl titanate with
g-c3n4Ratio be (1:0.5～2) ml/g, tio can be controlled2And g-c3n4Relative amount, make the fabric that finally obtains this
The photocatalysis effect of body is more preferably.Meanwhile, the volume adding acetic acid is the 0.6%～0.8% of ultrasonic reactor volume, can suppress
The too fast hydrolysis of butyl titanate, makes the tio of generation2Even particle size is controlled, and is uniformly supported on g-c3n4Surface.Profit
In in the surface of fabric body formation tio2/g-c3n4Layer obtains the fabric for processing dyeing waste water.
Start ultrasonic reactor so that the substance reaction in ultrasonic reactor is carried out in such a way, first 60 DEG C～
At 100 DEG C, ultrasonic constant temp reacts 2h～10h, then at 110 DEG C～160 DEG C, isothermal reaction 12h～48h, last 60 DEG C～
80 DEG C of ultrasonic constant temps keep 1/6h～1h, make the material mixing in ultrasonic reactor uniform, then at 110 DEG C～160 DEG C first
Under react, make tio2/g-c3n4Layer combines on the surface of fabric body, finally fabric body surface is combined unstable
tio2/g-c3n4Layer removes, it is to avoid its tio when processing dyeing waste water2/g-c3n4Layer is reunited, comes off.Wherein, temperature
The lifting of degree is all at the uniform velocity carried out, and can control tio2Granule is uniform, dispersion will not be reunited.During the course of the reaction, g-c3n4Quilt
Gradually peel off as lamellar structure, butyl titanate gradually hydrolyzes to form a nanometer tio simultaneously2Granule, loads to g-c3n4On lamella, lead to
Cross supersonic, water-heating method one layer of nanometer tio of area load in fabric body2/g-c3n4Layer, makes a nanometer tio2/g-c3n4Layer and fabric
