Description
Technical field
The present invention relates to a kind of methods using ozone and calper calcium peroxide combination processing methyl-red dye waste water, belong to environment
Pollute processing technology field.
Background technique
Textile printing and dyeing industry is important one of the conventional industries in China, with the development of printing and dyeing industry, textile printing and dyeing water
All there is the phenomenon that significantly increasing in amount and displacement, and Dying Wastewater Treatment & is also got worse.Fabrics printing and dyeing wastewater discharge is big,
Complicated composition, wherein pollutant concentration is high, and strong toxicity is difficult to degrade containing a large amount of complicated dyestuffs and compound, processing is difficult
It spends bigger.
Coloration height is that one of main feature of dyeing waste water, especially azo dyes and its byproduct have centainly carcinogenic
Property and mutability.Azo dyes is most commonly used one kind in dyestuff, it is to become one by azo group connection aromatic rings to grip altogether
System.It includes acidity, mordant dyeing, activity, cation, neutral dye, disperse dyes etc., and most of azo dyes is fragrance
Amine is coupled after diazotising with phenols, aromatic amine, active methylene compound.Since azo dyes structure is multiple
The physical methods such as miscellaneous therefore common absorption, flocculation and active sludge biological facture are all difficult to remove its coloration, if cannot
It is set to decolourize completely, it will to cause to seriously endanger to environment.
Methyl red (butter yellow o-carboxylic acid) is current most widely used azoic dye, and solid is presented
For one of purple crystal or red-brown powder, and common acid-base indicator, chemical structural formula such as formula (1) is shown:
In dyeing, the features such as methyl red is cheap, easily prepared due to its, contaminates industry, leather printing and dyeing in cloth
It has a wide range of applications in chemicalization industry, about accounting is 60%.At the beginning of 2017, the carcinogenic substance inventory that World Health Organization announces
Step arranges in reference, and methyl red is put into 3 class carcinogenic substance inventories.Therefore methyl red as the major pollutants in waste water from dyestuff it
One, it has received widespread attention in the treatment of waste water.Waste water from dyestuff complicated component containing methyl red, structure are difficult to break, and raw
Object degradability is very poor, Recent study discovery, can be by photochemical degradating, electrion degradation methyl red technique or using chemistry
Edman degradation Edman etc. removes the pollutant containing methyl-red dye, but all has that processing cost is high, the processing time is long, income is few substantially etc. and lack
Point.
Ozone oxidation is a kind of high-level oxidation technology, and oxidisability is strong, and reaction rate is fast and oxidation efficiency is high, to environment without
Noresidue is polluted, ozone obtains good actual processing effect in all kinds for the treatment of of dyeing wastewater fields in recent years.Ozone pair
The decoloration of dyeing waste water is highly effective, and ozone molecule can attack chromophoric group-conjugated double bond of dyestuff during ozone oxidation,
Make dyeing waste water quick decolorization and is degraded.But ozone oxidation is larger by water quality impact, for wastewater treatment, ozone drop
Solution causes operation cost higher vulnerable to influence inorganic and organic substance in waste water.
Calper calcium peroxide (CaO2) it is that white or light yellow crystalline powder referred to as " solid-state hydrogen peroxide " can when being dissolved in water
Slow release hydrogen peroxide (H2O2), and itself is nontoxic, thermal stability is significant, will not cause damages to environment.Calper calcium peroxide tool
There is stable oxidability, the effect in terms of degradable organic pollutant is better than the ozone with dosage, and transportation safety, dispensing letter
It is single, cheap, it is widely used in the fields such as reparation of wastewater treatment, soil and groundwater.
Summary of the invention
Problem to be solved by this invention is: the waste component containing methyl-red dye is complicated, structure is difficult to break, and biology
Degradability is very poor, contains methyl by photochemical degradating, electrion degradation methyl red technique or using removings such as chemical degradation methods
The disadvantages of pollutant process of red dye is at high cost, the processing time is long, income is few.
To solve the above-mentioned problems, the present invention provides methyl reds in a kind of ozone-calper calcium peroxide co-treating wastewater to contaminate
The method of material, which is characterized in that in the waste water of Xiang Hanyou methyl-red dye, be passed through ozone and add calper calcium peroxide, be sufficiently stirred
Afterwards, the methyl red in waste water can be removed.
Preferably, the initial concentration of methyl red is 0.01~5mg/L in the waste water；The initial pH value of the waste water is 3-
11。
Preferably, the ozone is generated by ozone generator by gas source of air, and gas flow is 24~60L/h.
Preferably, the dosage of the calper calcium peroxide is not more than 41.7mmol/L.
Preferably, the time of the stirring is 1~25min.
The present invention provides a kind of easy to operate, reaction condition is mild, high treating effect, short processing time, processing cost
It is low, the big method using ozone and calper calcium peroxide combination processing methyl-red dye waste water of industrial applications prospect.With it is existing
Technology is compared, the invention has the following advantages:
(1) reaction is mild, can quickly and efficiently make methyl red decolored degradation.It is combined at present about ozone and calper calcium peroxide
Handle methyl red organic wastewater research almost without.The present invention be passed through into the waste water containing methyl red it is a certain amount of smelly
Oxygen, while calper calcium peroxide medicament is added, ozone molecule directly attacks the chromophoric group of dyestuff, drops methyl red waste water quick decolorization
Solution；Calper calcium peroxide be dissolved in after water can slowly and for a long time oxidizing substances such as release hydroxyl radical free radical, in addition calper calcium peroxide can be
Solid phase interface is provided in gas-liquid oxidation system, the promotion effect of Interfacial Adsorption and activation is generated to ozone degradation organic matter, thus
Ozone can efficiently cooperate with removal methyl red with calper calcium peroxide combination.This method handles waste water containing methyl red, can in 25 minutes
Up to 90% or more removal rate.
(2) operating method is simple, and reaction condition is applied widely.The present invention be passed through into the waste water containing methyl red it is smelly
Oxygen and solid peroxygen calcium being added, reaction temperature is unlimited, suitable for the waste water of different background water-based, the concentration of methyl red in water
It can be 0.01-5 milligrams per liter.
(3) processing cost is low, and industrial applications prospect is big.The oxidant, ozone as used in the present invention and calper calcium peroxide at
This is low, easily obtains, and treatment process is simple and easy to do, and compared with other oxidants such as liquid hydrogen peroxide, solid peroxygen
Calcium convenient for storage transport, therefore ozone of the present invention-calper calcium peroxide combination oxidizing process have can industrial treatment contain methyl
The application prospect of red waste water.
(4) environmental-friendly.Ozone and calper calcium peroxide of the present invention and its oxidant of generation are in concentration model used
It encloses and interior secondary pollution not will cause to environment.
(5) it is wide to be applicable in target methyl red pollutant range.The present invention is suitable for the processing containing azo dye wastewater, need to be located
The methyl red structural formula of reason is as described in above-mentioned summary of the invention.
Detailed description of the invention
