Description
Technical field
The invention belongs to technical field of waste water processing, and in particular to a kind of to be gone using the produced exhaust-gas efficient of jerusalem artichoke core pretreatment
Except the method for methylene blue.
Background technology
China is traditional textile big country, and in recent years, with the proposition required structural transformation of the economy, textile fabric production is discarded
The improvement of object treatment technology will increasingly be taken seriously.Dyestuff is one of main pollutant in textile fabric production process,
Complicated component has bio-toxicity and refractory organics more, is a kind of waste water difficult to deal with.
At this stage, it is absorption method, membrane separation process, Ozonation and photocatalytic method to the conventional method of the processing of pollution.
Authorization Notice No. provides a kind of processing method of waste water from dyestuff for the Chinese patent of 102659235 B of CN, passes through
The mode of multiphase Fenton catalysis oxidations solves the deficiency of common homogeneous Fenton oxidation, has significantly increased for organic waste
The efficiency of water process.
Authorization Notice No. provides a kind of method of processing waste water from dyestuff for the Chinese patent of 103588307 B of CN, utilizes
Microorganism electrochemical coupled system realizes the promotion to the degradation efficiency of waste water from dyestuff, is gone to acid orange 7 and methyl orange
Except efficiency respectively reaches 79% and 89.8%.
Authorization Notice No. provides the ecology of a kind of dyestuff or dyestuff intermediate for the Chinese patent of 104725897 B of CN
Environment-friendly treatment method, by the way that water, alkaline agent and organic solvent are added in azo dyes or aromatic amine dyestuff, after heating reaction,
It can get higher removal effect.
Authorization Notice No. provides a kind of microwave of waste water from dyestuff for the Chinese patent of 103739035 B of CN and quickly handles
Method realizes the promotion to the degradation treatment efficiency of dyestuff using the technology of nano zero valence iron combination microwave treatment.
Authorization Notice No. provides for China of 104310559 B of CN and a kind of handling waste water from dyestuff using modified straw
Method, utilize absorption of the modified straw to dyestuff, realize to orange II, eriochrome black T decoloring dye waste water rate reach 95% with
On, 75% or more removal effect is reached to methylene blue dye wastewater percent of decolourization.
By above to the illustration of the treatment technology of existing waste water from dyestuff it is found that at present for the place of waste water from dyestuff
Reason, is typically based on solid absorbent or liquid reactions reagent carries out.Although the prior art realize to a certain extent " with
It is useless control it is useless ", by being modified processing to some industrial and agricultural production wastes, the product of removing dyestuff can be obtained, but this
The cost of a little modifications is usually higher, and the value of popularization and application is relatively low.Therefore, develop it is a kind of with existing production activity generate
Direct waste carry out " with it is useless directly control it is useless " handle dyestuff, be the project of next stage primary study.
Invention content
In view of the shortcomings of the prior art, the purpose of the present invention is to provide a kind of produced exhaust gas height is pre-processed using jerusalem artichoke core
The method of effect removal methylene blue, described method includes following steps：
It collects jerusalem artichoke core and pre-processes produced exhaust gas, be passed through equipped in the closed container in methylene blue waste liquid, in 30~80
Degradation reaction is carried out in DEG C；
The pretreated method of jerusalem artichoke core is：
Jerusalem artichoke core is put into reaction kettle, concentrated phosphoric acid-hydrogen peroxide mix reagent is added and carries out pretreatment reaction, wherein
The mass fraction of concentrated phosphoric acid is 60.0~70.0%, and the mass fraction of hydrogen peroxide is 5.0~8.0%.
The present inventor has carried out combining hydrogen peroxide using concentrated phosphoric acid in grant number is 103555774 B of CN
Preprocessing lignocellulose class raw material is used for the research of enzyme hydrolysis, and achieves outstanding technique effect.Enable inventor pleasantly surprised
It is that, when inventor utilizes the method in the patent, it is logical to carry out the exhaust gas generated in the preprocessing process using jerusalem artichoke core as raw material
When entering the waste water containing methylene blue, it is found that fast degradation occurs for methylene blue in waste.
Further, inventor is tested the palliating degradation degree of methylene blue, finds the removal efficiency of methylene blue
Unexpectedly reached 100%.That is, the present invention is better than existing general solid base and liquid for the removal effect of methylene blue
Sill.Those skilled in the art open a kind of processing mode of novel methylene blue in waste it is found that the present invention is undoubtedly.
Although being obviously improved sugared conversion ratio in 103555774 B of CN, important tribute is made that for bio-ethanol industry
It offers.However, the technology in practical application, inevitably generate some exhaust gas, causes pollution to a certain extent.Therefore,
Meaning of the present invention also resides in, and solves the problems, such as the recycling of the exhaust gas in 103555774 B of CN.
Currently, the present inventor still tests to gas componant therein, and probe into pollutant therein
Cutting mechanisms, while also carrying out corresponding scale application improvement.
The w/v of the jerusalem artichoke core and methylene blue waste liquid is 1:0.5~2.Unless otherwise instructed, in the present invention
Signified w/v is g/mL or kg/L.
As a preferred solution of the present invention, the w/v of the jerusalem artichoke core and methylene blue waste liquid is 8:7.5
As a preferred solution of the present invention, the mass fraction of concentrated phosphoric acid is 65.0%, the mass fraction of hydrogen peroxide
It is 7.0%.
As the preferred embodiment of the present invention, when carrying out the degradation reaction, reaction temperature is 50~80 DEG C.
As a preferred solution of the present invention, when carrying out the degradation reaction, reaction temperature is 50 DEG C.Because at 50 DEG C
Under, the removal rate of pollutant is very outstanding, for the angle for saving reaction cost, carries out pollutant at such a temperature
Removal processing is both economical.
The degradation reaction is progress synchronous with the pretreatment, and it is described close to pre-process being passed through for generated exhaust gas synchronization
It closes and carries out degradation reaction in container, that is to say, that pretreatment time is the degradation reaction time.
In general, when carrying out the pretreatment of jerusalem artichoke core, the time of the pretreatment reaction is 1~5h.
As a preferred solution of the present invention, when carrying out the pretreatment of jerusalem artichoke core, the time of the pretreatment reaction is 4h.
Beneficial effects of the present invention：
