Description
Technical field
The invention belongs to treatment method of printing and dying wastewater field, especially relate to a kind of useless without metal catalyst system degraded printing and dyeing
The method of water.
Background technology
China is weaving big country, and according to " whole nation environmental statistics publication " statistics display, China's textile waste discharge capacity reaches 20
Many hundred million tons, wherein dyeing waste water accounts for 80%, causes severe contamination to environment.Therefore, dyeing waste water is processed the most efficiently
It it is problem demanding prompt solution all the time.
At present, processing the more commonly used and effective method of dyeing waste water is Fenton method.Fenton method is advanced oxidation skill
The one of art, its reaction reagent is by ferrous ion and hydrogen peroxide (H2O2) composition, hydroxyl radical free radical (OH) tool that this reaction produces
Having the strongest oxidisability, its standard oxidationreduction potential is 1.8-2.7V, most organic pollutants of degrading to low toxicity, Yi Sheng
The little molecule of thing degraded even directly mineralising is inorganic matter.Although Fenton method have easily operated, without consume extraneous energy,
The advantages such as oxidation is thorough, but, the reaction of traditional F enton there is also some inherent shortcomings: (1) Fenton pH value in reaction is suitable for model
Enclose narrow, only carry out in the strong acid medium of 2-4;(2) present in reaction system, a large amount of iron ions are difficult to remove, and are easily formed
Mud, causes secondary pollution.
Along with the development of technology, new and effective water technology continues to bring out, have researcher use other oxidants or
Catalyst replaces hydrogen peroxide or ferrous ion to constitute Fenton-like system, achieves certain effect.(the Journal of such as Ling
Hazardous Materials, 2010,178:385-389.) use cobalt/permonosulphuric acid hydrogen salt (Co/PMS) system degradation of dye
Alkali blue, result shows, is under conditions of 0.13mM, PMS concentration is 0.4mM in Co ion concentration, and in 2min, alkali blue goes
Except rate is up to 100%.But there is cobalt ion overflow problem in this homogeneous system, and cobalt ion toxicity is very strong, can cause secondary pollution.
In known technology, " preparation method and the electricity class Fenton thereof of a kind of support type FeOOH catalyst give up Chinese patent CN 102218319
Water treatment system " disclose a kind of support type heterogeneous electricity preparation method of fenton catalyst FeOOH and catalytic effect, result
Finding, under the conditions of extra electric field, support type FeOOH catalyst constitutes out-phase electricity class Fenton oxidation system with hydrogen peroxide,
3.0gL-1Catalyst, 1.8gL-1Hydrogen peroxide, under the conditions of pH=6.8, in 1h, the amaranth azo dye of 200mg/L goes
Except rate is up to 100%.Chinese patent CN 102125848 " preparation of magnetic heterogeneous light Fenton and the side of degradable organic pollutant thereof
Method " disclose the preparation method of a kind of heterogeneous smooth fenton catalyst NiFe2O4, this catalyst has the catalysis activity of excellence,
Under 300W ultra violet lamp, catalyst system and catalyzing can remove the malachite green oxalate of more than 98%.Although above-mentioned catalyst system and catalyzing can efficiently drop
Solve dyeing waste water, but used catalyst all contains metal ion, the most inevitably exists a certain degree of
Metal loss problem, this greatly limits the actual application of catalyst system and catalyzing.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of utilization specifically can efficiently drop without metal catalyst system
Solve the method without metal catalyst system degraded dyeing waste water of dyeing waste water.
The technical solution adopted for the present invention to solve the technical problems is: a kind of without metal catalyst system degraded dyeing waste water
Method, dyeing waste water adds non-metal catalyst and oxidant, places and degrade, wherein non-metal catalyst is dense
Degree is 0.01-50mmol/L, and the concentration of oxidant is 0.01-100mmol/L, in this concentration range, and degradable dyeing waste water.
Further, described non-metal catalyst is surfactant or the inorganic matter of bromine ion-containing of bromine ion-containing.
Further, described non-metal catalyst is eight alkyl trimethyl ammonium bromides, Dodecyl trimethyl ammonium chloride
DTAB, Tetradecyl Trimethyl Ammonium Bromide TTAB, cetyl trimethylammonium bromide CTAB, Cetyltrimethylammonium bromide
One in OTAB or dodecyl triphenylphosphinebromide, in combination of two or more.
Further, described non-metal catalyst is cetyl trimethylammonium bromide CTAB or octadecyl trimethyl bromine
Change one or both combinations in ammonium OTAB.From the point of view of the effect of the degradation of dye waste water of the present invention, alkyl chain is the longest, degraded printing and dyeing
The effect of waste water is the best, and speed is the fastest.
Further, described non-metal catalyst is sodium bromide NaBr or ammonium bromide NH4Br.
Further, described oxidant is oxydol H2O2, one in persulfate PS or permonosulphuric acid hydrogen salt PMS, two
Plant or multiple combination.

In, can efficient degradation dyeing waste water.
Further, the concentration of described oxidant is 0.1-5mmol/L.Ensure oxidant concentration in this range, can be high
Effect degraded dyeing waste water.
There is no particular restriction to the pH of the dyeing waste water of degraded for the method for the present invention, it is adaptable to the fall of wide scope dyeing waste water
Solve.
The invention has the beneficial effects as follows: produced spike (catalyst by non-metal catalyst active oxidation agent at normal temperatures
Activation PMS produces hydroxyl radical free radical OH, and hydroxyl radical free radical has higher oxidation-reduction potential 1.8-2.7V) can be useless to printing and dyeing
Water carries out efficient degradation, not only overcomes the method secondary pollution of traditional F enton, low, the pH narrow application range of hydrogen peroxide utilization rate etc. no
Foot, and reaction condition is gentle, and removal effect is obvious, and without metallic pollution, little to environmental hazard, catalyst amount is few, operation letter
Single, low cost.
