Description
Technical field
It is specially that one kind utilizes Fe-based amorphous alloy activation peroxydisulfate drop the present invention relates to a kind of method of wastewater treatment
The method for solving waste water from dyestuff.
Background technology
As industrialization is developed rapidly, water consumption is sharply increased, and discharged volume of industrial waste water also increases sharply.Wherein dyestuff gives up
Water accounts for 1/10th of industrial wastewater total release, it has also become the important pollution sources in water environment, such waste water has structure
Complicated, bio-refractory and the features such as endangering is constituted to health, be the organic wastewater of generally acknowledged difficult degradation.
At present, dye waste water treatment method mainly has physisorphtion, advanced oxidation processes, chemical oxidization method, biodegradation
Method and chemical flocculation etc., and the method for these degradation of dye waste water has cost height, efficiency is low, be also easy to produce the offices such as secondary pollution
It is sex-limited.For example, the advanced oxidation processes for producing hydroxyl radical free radical using hydrogen peroxide have its weak point, dioxygen water use efficiency is low, steady
It is qualitative difference and have the shortcomings that specifically to require to the acid-base value of waste water from dyestuff；A kind of too strong, the biological bacteria of biological degradation method selectivity
Only often there is degradation effect to certain or certain several dyestuff, and also have specific requirement to the acid-base value of waste water from dyestuff；Change
Learning flocculence has very strong selectivity, and there is the shortcomings of dosage is excessive, precipitating sludge is excessive.
Recently, with persulfate oxidation method degradation of dye waste water turn into study hotspot, it by the use of potentiometric titrations as
Oxidant carrys out degradation of dye waste water.And conventional persulfate activation method has thermal activation, transition metal activation and ultraviolet light to live
Change.It is also study hotspot wherein to produce potentiometric titrations degradation of dye waste water with transition metal activation persulfate.But at present
Persulfate is activated using ferrous ion and produces the inefficient of potentiometric titrations, causes the oxidative degradation to waste water from dyestuff to be imitated
Fruit is affected；Although nano ferriferrous oxide activation persulfate degradation efficiency is improved, nano ferriferrous oxide is easy
Reunite, it is difficult to ensure that its characteristics of nanoparticles after recovery, therefore be unfavorable for recycling, and easily cause secondary pollution etc. lacking
Point.
In Fe-based amorphous alloy, iron exists with atomic state, and remain that iron has in itself removes color function, is that a kind of have very much should
With the material of the activation persulfate of value.
The content of the invention
It is an object of the invention to provide a kind of utilization Fe-based amorphous alloy activation peroxydisulfate degradation of dye waste water
Method, both removed color function, while also utilizing Zero-valent Iron in Fe-based amorphous alloy using what iron in Fe-based amorphous alloy had in itself
