Decompose a variety of dyestuffs, the reusable, manufacturing method of fiber that is easy to separate with water body.The manufacturing method integrated use is heavy
Technologies, the gained fibers such as shallow lake polymerization, wet spinning, penetrating power promotion, iron ion complexing, heat cross-linking can be used for waste water from dyestuff etc.
The processing of the water body containing organic matter.
Background technique
It is constantly progressive with the rapid development of society with industrial, the water pollution problems being on the rise is to the existence of the mankind
Safety constitutes significant threat, becomes the major obstacles of human health, economy and society sustainable development.And textile printing and dyeing industry is made
For typical highly water intensive industry, production process process is sufficiently complex, need to consume nearly hundred million tons of water every year, thus generate a large amount of dyestuff
Waste water causes serious environmental problem.(Guangwei Zhang, Idzumi Okajima, Takeshi Sako,
Decomposition and decoloration of dyeing wastewater by hydrothermal
Oxidation, The Journal of Supercritical Fluids, 2016,112 (1): 136-142;Terinte N,
Manda B M K, Taylor J, et al, Environmental assessment of coloured fabrics and
Opportunities for value creation:Spin-dyeing versus conventional dyeing of
Modal fabrics, Journal of Cleaner Production, 2014,72 (6): 127-138).Waste water from dyestuff at
It is point sufficiently complex, have the characteristics that water is big, change of water quality is big, high organic content, coloration height, biodegradability are poor, and contain more
Organic matter with bio-toxicity or " three cause property " (carcinogenic, teratogenesis and mutagenicity), direct emission can bring living environment
High risks, while the waste of water resource is caused, and as state and society is to the pay attention to day by day of environmental protection requirement, it is traditional
Dye waste water treatment method have been unable to meet production and environmental protection requirement, therefore, at present dye wastewater treatment field there is an urgent need to
Seek efficient, inexpensive processing material and technology (Ay F, Catalkaya E C, Kargi F, A statistical
experiment design approach for advanced oxidation of Direct Red azo-dye by
Photo-Fenton treatment, 2009,162 (1): 230-236).
Since the 1980s, countries in the world environmental science and technology has been caused to generate the high-level oxidation technology that OH is mark
The attention on boundary, due to high-level oxidation technology have the characteristics that oxidability by force and it is without secondary pollution, so be considered as processing water
Middle hardly degraded organic substance most has the technology of application prospect.Compared with other high-level oxidation technologies, Fenton method is due to having reaction
Rapidly, oxidability is strong, good decolorizing effect and the features such as strong flexibility, it is considered to be is widely used at present and with development potential
One of dye waste water treatment method.Fenton system passes through Fe2+With H2O2Reaction generates the OH with high reaction activity,
And OH has the Strong oxdiative ability for being only second to fluorine, can be produced with oxygenolysis organic pollutant, intermediate as oxidation process
Object can induce subsequent chain reaction, and the substance of certain difficult for biological degradation is made to be transformed into the substance of easy biological treatment, and
The chromogenic or auxochrome group for destroying dyestuff, makes it lose color development ability, so that coloring matter is made to degrade, organic pollutant is thorough
It is harmless to turn to carbon dioxide and water.Chemical reaction condition needed for Fenton system is mild, easy to accomplish, and oxidation reaction does not have
Have introduce other poisonous and harmful substances, for waste water from dyestuff improvement open new approach (Ayoub K, N é lieu S,
Hullebusch E D V, et al., TNT oxidation by Fenton reaction:Reagent ratio effect
On kinetics and early stage degradation pathways, Chemical Engineering
Journal, 2011,173 (2): 309-317).
Currently, Fenton reaction system mainly includes the homogeneous and big reaction system of out-phase two, to further increase organic matter
Removal effect, by optics, ultrasonic technology and electrochemical techniques etc. be dissolved into Fenton reaction in form novel homogeneous
Fenton reaction system (Babuponnusami A, Muthukumar K, A review on Fenton and
Improvements to the Fenton process for wastewater treatment, Journal of
Environmental Chemical Engineering, 2014,2 (1): 557-572;Han Z, Dong Y, Dong S,
Copper-iron bimetal modified PAN fiber complexes as novel heterogeneous
Fenton catalysts for degradation of organic dye under visible light
Irradiation, Journal of Hazardous Materials, 2011,189 (1-2): 241-248), but it is common homogeneous
Fenton reaction system is still that Fenton method processing dyestuff is useless with the absolute predominance in terms of cost and technical feasibility
Common reaction system when water.But for common homogeneous Fenton reaction system, because its only at lower pH
It can be effectively carried out, need to adjust waste water repeatedly pH value to acidity, increase processing cost, and homogeneous Fenton reaction system
Catalyst it is miscible in waste water in the form of an ion, homogeneous catalyst and reactant, reaction product mixing, cause using rear catalysis
Agent is difficult to separate, and generates a large amount of iron cements, and post-processing is complicated, waste reaction resource, and improves use cost, limits homogeneous
The application of Fenton reaction system.
With in Fenton reaction system catalyst research deeply and the enhancing of mankind's environmental consciousness, by divalent or
Ferric ion, other ions and compound ion are supported on certain carrier, form heterogeneous Fenton catalyst, different
Phase Fenton reaction system can handle waste water from dyestuff within the scope of wide pH, i.e., organic molecule is adsorbed onto catalyst table first
Face, in active component and H2O2Under the action of, organic molecule decomposes, and the product desorption after degradation simultaneously returns in solution, in turn
Pollutant process is completed, and heterogeneous Fenton catalyst can be separated with aqueous systems easily, and then can be repeatedly used, In
During this, since the iron ion amount of elution is few, therefore a large amount of iron cements (Zeng X, Lemley A T, Fenton will not be generated
Degradation of 4,6-Dinitro-o-cresol with Fe2+- Substituted Ion-Exchange Resin,
Journal of Agricultural&Food Chemistry, 2009,57 (9): 3689-3694).It follows that out-phase
Fenton reaction system had not only remained the advantages of homogeneous Fenton reaction, but also significantly compensated for its deficiency, was greatly simplifying processing
On process base, it can greatly expand wastewater treatment range, it has also become an important development of Fenton method processing organic wastewater
Direction will also play a positive role in the treatment of waste water, have fabulous application prospect.
Currently, heterophase Fenton catalyst mainly includes load typed iron catalyst, iron powder or iron ore catalyst etc..Load
Sections catalyst can preferably solve the secondary pollution problems of iron ion in homogeneous Fenton system, and carrier is either have
Airborne body, is also possible to inorganic carrier, and Nafion membrane is a kind of cation exchange being made of perfluorinated sulfonic acid anionic polymer
Film has many advantages, such as that heat-resisting, corrosion-resistant and intensity is high, but since Nafion membrane is expensive, also needs to consider film in practical application
Oxidation resistance and (Wu Wei, Wu Chengcheng, Zhao Yaping, heterogeneous Fenton technology degradable organic pollutant the problems such as fouling membrane
Progress, Environmental science and technology, 2010,06:99-104);In addition, some macromolecular organic compounds such as sodium alginate
Deng also can be used as immobilization carrier (Cruz A, Couto L, Esplugas S, et al., Study of the
contribution of homogeneous catalysis on heterogeneous Fe(III)/alginate
Mediated photo-Fenton process, Chemical Engineering Journal, 2016,318:272-280),
But such carrier is difficult to be subjected to the oxidation corrosion of OH.In inorganic material, aluminium oxide is a kind of common catalyst carrier, molecule
Sieve be also commonly used as catalyst carrier (Zhou Yaliang, Huang Dongyue, the type and progress of Fenton's reaction technology, Guangdong chemical industry,
2013,40 (1): 74-74);Clay, main component are kaolin, frequently as iron ion carrier (Li Huanyu, it is heterogeneous
The progress of Fenton reaction treatment organic pollutant, building and budget, 2015,06:47-50), using inorganic material as carrier
Heterogeneous Fenton catalyst there is at low cost, the advantages such as specific surface area height and adsorption capacity are strong, but catalyst preparation mistake
Journey is complicated, and fine catalyst is difficult to recycle, and application is restricted.Iron powder or iron ore catalyst are primarily present in nature ore
In, magnetic material has magnetic iron ore, maghemite, perovskite, lepidocrocite and spinelle etc., and non-magnetic material has bloodstone and needle iron
Mine etc., iron powder and these mineral materials itself can be with H2O2Constitute Fenton system come degradation of organic substances (Khataee A,

Catalysts and their application in heterogeneous Fenton oxidation-A review,
Applied Catalysis B Environmental, 2015,176:249-265), but ferriferous oxide Fenton reaction system
It is affected by pH, in acid condition, the dissolution of iron ion can induce H2O2OH is generated, but the iron ion dissolved out is eventually given birth to
At iron cement, cause secondary pollution, and ore iron type is less and limited source, limit it and further apply.
In the above context, novel carriers material is researched and developed, keeps iron ion or iron oxide securely and equal
It loads evenly on it, is easily isolated solid-liquid while improving catalytic performance;On the other hand, in the same of selection suitable carrier
When iron species are modified, be made excellent combination property heterogeneous Fenton catalyst, become great real value.
The present invention selects suitable polymerized monomer first, using precipitation polymerization method synthesis rich in the poly- of specific functional groups carboxyl, hydroxyl etc.

Fiber, to reduce osmotic resistance when iron ion adsorbs and fixes, thus make within the limited time fibrous inside be full of iron from
Son, iron ion load capacity increase, through thermal crosslinking treatment after, make to be dehydrated between amount of activated group carboxyl and hydroxyl and form friendship
Join network structure, cross-linked network structure fetter iron ion, along between carboxyl, hydroxyl and iron ion strong complexing and
The constraint of fiber surface acts on, and is securely joined with iron ion more in fibrous inside, iron ion washes when greatly reducing application
De- amount assigns finished fiber fabulous reusability, becomes heterogeneous Fenton catalyst truly, together
When in thermal crosslinking treatment, selected using atmosphere in high temperature furnace, realize and the existence form, form, crystal form of iron species are carried out
Modification, further enhances its catalytic activity, to the processing for water bodys containing organic matter such as waste water from dyestuff, for reaching for above-mentioned water body
New processing material is developed in mark discharge.
