Description
Technical field
The present invention relates to field of waste water treatment, more particularly to a kind of handling process of disperse red 60 production waste water.
Background technology
The chemical name of disperse red 60 is 1- amino -2- phenoxy group -4- hydroxy-anthraquiones, and dry product is dark red powder, structure
Formula is：
Disperse red 60 is mainly used in the dyeing of terylene and its blend fabric, its staining power height, bright in color light, has well
Hoisting power, blending dyeing can be carried out with a variety of blue, weld compatibilities, always as one of dyestuff three primary colors, have pole
Its consequence；It can also be used for the production of ink etc. simultaneously；Further to improve the application performance of dyestuff, fraction 60 also may be used
As intermediate by being processed further producing the more excellent dyestuff of performance, such as disperse red 91, disperse red 92 and disperse red
191 etc..
The most frequently used production method of disperse red 60 is using 1- amino anthraquinones as raw material, reacts and makes with bromine in sulfuric acid medium
The bromo- 1- amino anthraquinones of 2,4- bis- is obtained, heating hydrolysis obtains the bromo- 4- of 1- amino -2- to the reactant directly in sulfuric acid without isolation
Hydroxy-anthraquione, product is isolated, filters, washs, after drying, is condensed in phenol medium, 1- amino -2- phenoxy groups -4- is made
Hydroxy-anthraquione, i.e. disperse red 60.When 1- AMINO 2 BROMO 4 HYDROXY ANTHRAQUINONEs are condensed with phenol, the two mol ratio is 1: 6 left
The right side, after condensation reaction, the retortable recovery of most of phenol in condensation waste water, but after dilution filters, also 2~4%
Phenol remain in condensation waste water.
Phenol has stable benzene ring structure, not degradable, thus its waste water is more intractable.Directly handled using biochemical process
Phenolic waste water is difficult to reach preferable treatment effect, the typically thing first with strong oxidizer by oxidation of phenol for easily biological-degradable
Biochemical treatment is further carried out after matter.
The common technology of disperse red 60 condensation waste water is Fenton oxidation-flocculation treatment method, that is, adds a certain amount of sulfuric acid
Ferrous and hydrogen peroxide, react 1 hour under the conditions of 40 DEG C~50 DEG C, and maintenance pH utilizes liquid caustic soda 3 or so afterwards in course of reaction
Or ammoniacal liquor regulation pH is 8 or so, filtering.But dioxygen water consumption is larger during Fenton oxidation, cause to be processed into
This increases significantly, and a large amount of foams generations and exothermic phenomenon are had in oxidizing process, is unfavorable for the progress of reaction；
After Fenton reactions terminate, liquid caustic soda need to be added and flocculated, but iron ion is not easy to remove completely, and have the production of iron cement solid waste
It is raw.
The content of the invention
The invention provides a kind of handling process of disperse red 60 production waste water, the phenol in waste water can be effectively removed, instead
Answer mild condition, running cost is relatively low.
A kind of handling process of disperse red 60 production waste water, including：
(1) precipitate：The pH of disperse red 60 production waste water is adjusted to 2~5, nitrite reaction is added, after reaction terminates
Filtering, obtains filtrate；
(2) aoxidize：Filtrate is mixed with aqueous solution of chlorine dioxide, regulation mixed liquor to neutrality, oxidation reaction is carried out, obtains
Handle water outlet.
In disperse red 60 production waste water, particularly condensation waste water, substantial amounts of phenol be present, phenol has stable phenyl ring knot
Structure and there is bio-toxicity, belong to hardly degraded organic substance.The handling process of the present invention is served as theme with precipitating-aoxidizing, and condensation is useless
Water is adjusted to acidity, adds nitrite thereto, substitution reaction mainly occurs, and substitutes the reaction product of generation water-soluble
Difference, easily precipitation；In addition, the phenol in alkaline environment is dissolved in the water in the form of phenolate, produced when waste water is adjusted to acidity
Raw phenol is water-soluble to be deteriorated, simultaneously, and phenol is easily oxidized to quinone, and quinones may be polymerized reaction generation polymer, etc..
A large amount of insoluble substances are produced on this condition, it is removed by filtration；The a small amount of phenol and other organic matters remained in filtrate leads to
Later continuous oxidation, resolves into biodegradable small organic molecule, is easy to handle water outlet progress subsequent treatment, such as can enter
Row biological treatment.
The handling process of the present invention introduces precipitation reaction in the treatment of waste water, and nitrite produces insoluble with phenol precipitation
Product, reaction condition is also relatively gentle, and cost is relatively low.By the precipitation of step (1), can remove most organic in waste water
Thing, the clearance that the clearance of phenol in wastewater reaches more than 75%, COD reach more than 80%.
Preferably, the precipitation reaction time is 0.5~8h.In gained filtrate the mass concentration of phenol can reach 0.15% with
Under.
Although chlorine dioxide has strong oxidizing property, its oxidation efficiency is relatively low, and oxidation cost is high, is removed by precipitation reaction
Most of organic matter in waste water, is greatly improved the oxidation efficiency of subsequent oxidation process, and can substantially reduce chlorine dioxide
Usage amount, reduce production cost.
Preferably, described nitrite is natrium nitrosum or potassium nitrite.
Precipitation reaction is incomplete when the dosage of nitrite is too small, when the dosage of nitrite is excessive, remaining Asia
Nitrate can consume oxidant in follow-up oxidation step, increase the usage amount of oxidant, reduce oxidation efficiency.
Preferably, in step (1), after adding nitrite, disperse red 60 production waste water nitrite and phenol
Mass ratio is 1~2: 1.
In precipitation process, because of tarry matters meeting wall built-up or caking caused by reaction product coking, preferably, step
(1) in, in precipitation process, produced to disperse red 60 and adsorbent is added in waste water, the dosage of adsorbent produces for disperse red 60
The 1~50% of phenol in wastewater quality.
Adsorbent is added in precipitation process, caking precipitation or wall built-up can be effectively prevented, be not added with adsorbent or adsorbent
Dosage it is too small when, a large amount of tarry impurity are produced in precipitation process, cause filter plant damage, filtrate COD rise,
Subsequent oxidation effect is poor.
It is further preferred that the dosage of adsorbent, which is disperse red 60, produces the 5~20% of phenol in wastewater quality.
It is further preferred that described adsorbent is activated carbon.
Preferably, in step (2), the mass concentration of described aqueous solution of chlorine dioxide is 0.02~0.2%, titanium dioxide
The volume ratio of chlorine water solution and filtrate is 0.5~2: 1.
Individually aoxidized using chlorine dioxide, oxidation efficiency is relatively low, can add catalyst and carry out catalysis oxidation, as excellent
Select, in step (2), add catalyst, the catalyst is using activated carbon as carrier, with one kind in Fe, Ni, Cu, Zn, Mn and Ce
Or a variety of oxides is active component.
Preferably, described processing water outlet prepares aqueous solution of chlorine dioxide after absorbing chlorine dioxide, step (2) is back to
In.
Will processing effluent reuse in step (2), can greatly save with water, while also reduce the load of subsequent treatment.
Compared with prior art, the present patent application has the beneficial effect that：
(1) a small amount of nitrite need to be only added when precipitating can generate the insoluble macromolecular precipitated product of precipitation, instead
Answer condition also relatively gentleer, cost is relatively low；
(2) using the phenol and other organic matters of Chlorine Dioxide Oxidation residual after precipitating, it is broken down into what is easily degraded
Small organic molecule, reduces the difficulty of processing water outlet subsequent treatment, such as can carry out biological treatment.
