Abstract
The invention discloses the preparation methods that one kind can efficiently activate the tire C catalyst of persulfate, comprising the following steps: the carrier tire carbon of catalyst is first made by processes such as broken, magnetic separation and low temperature pyrogenation with waste tire, then by CuO, CeO2、Fe2O3、Bi2O3、Co2O3Using obtaining a kind of new and effective catalyst suitable for persulfate system after the processes such as dipping, kneading, pyrolysis.The advantages that catalyst prepared by the present invention is active high, activity component impregnation amount is few, preparation is simple, technology maturation, stability are good and at low cost in persulfate system, can be applied to the fields such as sewage treatment and environmental improvement.It is waste tire that it is raw materials used, which to prepare catalyst, by the present invention, damaged tire can be turned waste into wealth, and abundant resource utilization realizes waste treatment and waste, and has significant economic benefit.The present invention also provides the methods that the catalyst is used for degradation of organic waste water, can reach 95% or more to organic wastewater removal rate, can meet country-level wastewater discharge standard.
Description
Technical field
The present invention relates to the preparation methods and application of a kind of efficiently activation persulfate tire C catalyst, are suitable for over cure
Hydrochlorate oxidation processes organic wastewater, belongs to water treatment technology and environment functional material field.
Background technique
Chemical industry is important one of the industry in China, is occupied an important position in China's development.However, chemical industry flies
The problem of speed develops simultaneously, bring water environment pollution is also on the rise.A large amount of organic wastewater with difficult degradation thereby that chemical industry generates,
It is a big difficulty of wastewater treatment.In recent years, antibiotic waste water receives more and more attention.Antibiotic is widely used in controlling
Treat communicable disease and disease prevention and growth promotion etc..Although antibiotic is compared with Conventional pollution, in waste water
Content is lower, but conventional sewage treatment process can not be removed it effectively, into environment after human health can be caused
Potential threat.Wherein, Ofloxacin is usually used in acute and chronic infection caused by treating bacterium, since research and development, has become as clinic master
One of anti-infectives wanted, annual usage amount both at home and abroad are huge.However Ofloxacin mainly exists in the form of raw medicine, and difficult
It is degraded, so that abundant residues in water environment, cause serious environmental hazard.
The processing technique about organic wastewater studied both at home and abroad is mainly high-level oxidation technology, such as Fenton reagent
Method, Ozonation, catalytic oxidation etc..Grinding about potassium hydrogen persulfate catalysis oxidation organic wastewater and its influence factor at present
Study carefully less.Persulfate system is the oxidation system based on potentiometric titrations, has oxidability strong, selective strong
Advantage.Compared to hydrogen peroxide, the applicable pH range of persulfate is wider.The method of activation persulfate used at present has hot place
Reason, ultraviolet radioactive, electro-catalysis and transition metal ion catalyst etc..Wherein transition metal activation method has easy to operate and reaction item
The mild advantage of part, but since metal ion can not reuse and need to remove after the completion of reaction, increase operation
It will also result in water pollution problem while cost.Heterogeneous activation persulfate technology can be a large amount of to avoid introducing into water body
The defect of metal ion, catalyst recycle after can reacting.Therefore, there is an urgent need to develop with prepare and can efficiently activate
Persulfate heterogeneous catalysis economical and practical simultaneously.
With the fast development of auto industry, the yield of waste tire also increases sharply, and a large amount of waste tire is given
Environmental improvement brings immense pressure.Waste tire is also referred to as " black pollution ", and recycling and processing problem are always one
Hang-up.It is not only taken up a large area using the method buried or stacked, it is also extremely easy to cause fire；Waste tire renovation, production
The processes such as rubber powder can generate volatile organic contaminant；The process that incineration method recovers energy can also generate dioxin, furans and more
The polluters such as cycloaromatics.However, the tire carbon prepared using waste tire, finds that the carbon material has than table after study
The big feature of area, and there is certain catalytic activity, it is available that there is height using the method for preparing catalyst of this patent
Imitate the catalyst of catalytic activity.It can be waste tire after this catalyst prepared by waste tire is applied to reality
Processing disposition provides a kind of new mode, mitigates the pollution of waste tire bring, sufficiently by its resource utilization, reaches and is controlled with useless
Useless purpose, so this kind of catalyst has a good application prospect.
To sum up, using tire carbon as active component carrier, then by CuO, CeO2、Fe2O3、Bi2O3、Co2O3In
One or more loaded on tire carbon carrier as active component, using after the processes such as dipping, kneading, pyrolysis
To a kind of new and effective catalyst suitable for persulfate system.This catalyst is for persulfate oxidation degradation organic waste
Water not only has high degradation rate, cost advantage, also changes the waste property of tire carbon, realize tire carbon functionalization and
Resource utilization.Therefore, such catalyst will be more widely used.
Summary of the invention
The purpose of the present invention is to propose to one kind in persulfate oxidation system, have the stable structure of processing organic wastewater
With the preparation method and applications of high activated catalyst, using tire carbon as active component carrier, then by CuO, CeO2、
Fe2O3、Bi2O3、Co2O3One or more of load on tire carbon carrier as active component, the active component
Its load capacity is 0.1~5.0wt.% in terms of metal.Using preparing a kind of novel height after the processes such as dipping, kneading, pyrolysis
Effect is suitable for the catalyst of persulfate system.Under persulfate oxidation system, catalytic oxidation treatment organic wastewater.Specific mistake
