Description
Technical field
The present invention relates to dyeing and printing sewage processing technology field, and in particular to a kind of processing method of dyeing and printing sewage.
Background technology
Water process is the eternal problem of the mankind.With China's economic development, national water consumption rises year by year, and discharge of wastewater is total
Amount increases, and increased wastewater emission amount causes the increase of water process pressure year by year.Textile industry is the traditional pillar industry in China,
" three wastes " discharged in dyeing production process, especially waste water, environment will be caused seriously to pollute if improvement is improper.
According to incompletely statistics, dyeing waste water daily discharge capacity in China's is 400~600 ten thousand steres.Dyeing waste water has water big, organic
The features such as pollutant concentration is high, colourity is deep, alkalescence is high, change of water quality is big, complicated component, belong to industrial wastewater difficult to deal with it
One.
Traditional sewage water treatment method is such as sterilized, purified, the high strength chemical processing of desalination can solve many pollutions and ask
Topic.However, these methods are generally required for consuming substantial amounts of manpower and energy, and can only be by needing substantial amounts of fund, work
Larger processing system that journey technology and infrastructure are supported and realize, therefore many places can not all make to carry out dirt in this way
Water process, hamper its promotion and application worldwide.In addition, the chemical treatment of high intensity (such as is related to ammonia, chlorination
Thing, hydrochloric acid, sodium hydroxide, ozone, potassium permanganate, alum and molysite, coagulating agent and help and consider agent, the corrosion control such as antisludging agent chemistry
Medicament, and ion exchange resin and regenerative agent etc. chemical treatment) and its residue (sludge, bittern, toxic waste etc.) all can
Become a source of fresh water pollution and salinization of soil.
In recent years, iron/water micro electrolysis tech is used for sewage disposal, and this method, which almost can be used in handling, all can not give birth to
Change the waste water of processing, while can also water-borne pathogens be played with killing action, and ferro element reserves in the earth's crust are huge, valency
Lattice are cheap, and this method without strong oxidizer, therefore is considered as a kind of environment-friendly processing without additional equipment in addition
Method.At present, iron powder and cast iron scrap have been widely used in the processing of dyeing waste water.
But during reduced iron powder processing dyeing waste water, there are the following problems：(1) iron powder is often business and mark
Brick；Compared with reduced iron powder, the index such as the purity of cast iron scrap, activity is poor, results in the need for longer processing time and can be only achieved
The standard of subsequent treatment；(2) this method be there are certain requirements to the pH value of dyeing waste water, and this is just needed to large batch of printing and dyeing
Waste water carries out pH value adjustment, causes practical application inconvenient；(3) there is serious hardened problem in iron/water light electrolysis；Using receiving
It is both to possess bigger specific surface area although rice iron powder can prevent hardened to a certain degree, the manufacture of nanometer iron powder is difficult
Degree is very high, it is difficult to industrialized production is realized, it is with high costs；(4) because reduced iron powder and cast-iron scrap are in actual dyeing waste water
Serious oxidation can occur in processing procedure, cause the corrosion of iron to consume, and due to iron easily with acid reaction, by pickling and
The poor operability of the recovery of its surface reduction ability is realized, the recycling to reduced iron powder or cast iron scrap brings difficulty, past
Toward wastewater treatment of progress is only capable of, the cost rise of this method is caused, limits its extensive use.
In order to make up dyeing waste water handle using reduced iron powder or cast iron scrap existing treatment conditions it is more,
Treatment effect is bad, and the shortcomings of repeatable usability difference, Fe base amorphous ribbons are made by amorphization techniques in scientific research personnel,
The research using Fe bases amorphous ribbon processing dyeing waste water is carried out.Iron exists with atomic state in Fe base noncrystal alloys, remains
What Zero-valent Iron had in itself removes color function, and has Fe-based amorphous and strip sample advantage concurrently, is a kind of good printing and dyeing water
Except color material.But the efficiency of Fe bases amorphous ribbon processing dyeing and printing sewage is still relatively low, is not met by dyeing and printing sewage processing
Actual demand.
The content of the invention
For the above-mentioned state of the art, the present invention is intended to provide a kind of new method of dyeing and printing sewage processing, this method are simply easy
OK, it is higher to the treatment effeciency of dyeing and printing sewage.
In order to realize above-mentioned technical purpose, the present invention has carried out many experiments exploration.One of which method is：Utilizing
During iron/water micro electrolysis tech is handled dyeing and printing sewage, Fe base amorphous ribbons are replaced with Fe-based amorphous alloy powder.Should
Method is intended to improve the specific surface area of Fe-based amorphous alloy, so as to improve the treatment effect of dyeing and printing sewage.But using this method
When, present inventors have surprisingly found that：Fe base amorphous ribbons are replaced with Fe-based amorphous alloy powder, it is non-iron-based can not only to be effectively improved
The specific surface area of peritectic alloy, and the Fe-based amorphous alloy powder with the mistake of (degraded azo dyes) of being reacted to dyeing and printing sewage
Cheng Zhong, surface can form nano-porous structure, and the nano-porous structure not only further increases the ratio of the Fe-based amorphous alloy
Surface area, and play a part of adsorbing azo dyes and reaction product during the course of the reaction, it is dirty so as to substantially increase printing and dyeing
The treatment effeciency of water.
That is, the technical scheme is that：A kind of processing method of dyeing and printing sewage, from ferrous alloy raw material, the iron-based
Alloy raw material possesses ferrum-based amorphous alloy strip Forming ability；Raw material is prepared as ferrum-based amorphous alloy strip, after embrittlement processing
Crush, obtained Fe-based amorphous alloy powder, its a diameter of 10 μm~200 μm；Fe-based amorphous alloy powder is used for dyeing and printing sewage
Processing.
In the component of described Fe-based amorphous alloy, the atomic percent of iron is preferably between 60%~90%
Preferably, to play the reduction-decolor ability of iron atom, other elements are unlimited, choose according to the actual requirements, can be Si, B, Nb, Cu,
One kind in the element for advantageously forming Fe-based amorphous alloy that rare earth elements RE and existing literature and technical data are related to or
It is several.
As a kind of implementation, the molecular formula of described Fe-based amorphous alloy is FeaSibBcMd, wherein subscript a, b, c,
D represents the atomic percentage conc of corresponding element, and span is 60≤a≤90,0≤b≤20,5≤c≤30,0≤d≤30, and

It is several.Preferably, the purity of Fe, Si, B and M element is not less than 99% (percentage by weight).For example, the Fe-based amorphous conjunction
The molecular formula of gold is Fe78Si9B13、Fe77Si9B13La1、Fe73Si7B17Mo3、Fe73Si7B17Nb1Gd2、Fe75Si9B13Nb2Tb1、
Fe75Si9B13Tm3、Fe77Si9B13Y1Deng.
The method for preparing ferrum-based amorphous alloy strip using the ferrous alloy raw material is：Melting iron-based closes in electric arc furnaces
Golden raw material, melting uniformly, after cooling obtain mother alloy ingot；Then, mother alloy ingot is sensed in induction melting furnace
Molten metal, after substantially uniformity is molten into molten metal, is sprayed onto on the disk roller for get rid of carrying device and carries out getting rid of band by fusing by instantaneous differential pressure,
Obtain ferrum-based amorphous alloy strip.According to the amorphous formation ability of ferrous alloy composition, the roller speed for getting rid of carrying device typically selects
Select in 25~38m/s.
Described brittle processing method is unlimited, including carries out embrittlement using annealing process, and annealing temperature is less than Glass Transition
