Description
Technical field
The present invention provides a kind of method for handling methylene blue waste water, belongs to dye wastewater treatment field.
Background technique
The processing method of textile printing and dyeing wastewater has absorption method, flocculence, electrolysis method, bioanalysis and advanced oxidation processes.
The disadvantages of Fenton oxidation method is most common advanced oxidation processes, but there are reaction time length, pH narrow application range.Fenton-like
Oxidizing process has and is not controlled by pH value, and reaction product is only the advantage of clean carbon dioxide and water.The oxide of manganese is exactly one
The typical Fenton-like type catalyst of kind, catalytic activity with higher.However metal oxide preparation process is complicated, synthesis temperature
Degree is high, the period is long.
Metallosilicate material has had both the dual characteristics of the multivalent state of metal oxide and the structural stability of silicate,
Resourceful, cheap, reactivity is higher, and is easy preparation.However do not make in the prior art about by manganous silicate also
It is used to handle the report of methylene blue waste water for Fenton-like type catalyst.The present invention provides a kind of processing methylene blue waste water
Method, for silicate material further application have great importance.
Summary of the invention
The object of the present invention is to provide a kind of methods for handling methylene blue waste water, to achieve the above object, institute of the present invention
The technical scheme steps of use are as follows:
A method of processing methylene blue waste water, which is characterized in that at room temperature, in methylene blue waste water be added manganous silicate and
Hydrogen peroxide is kept for 60 minutes under stirring, is catalyzed fenton-type reagent reaction by manganous silicate, is realized methylene blue
Removal.
The methylene blue wastewater treatment method, which is characterized in that methylene blue methylene blue in waste, manganous silicate and
The content of hydrogen peroxide is respectively 0.05g/L, 0.1g/L, 16.7g/L.
Beneficial effects of the present invention:
(1) method of a kind of processing methylene blue waste water of the invention, simple process handle the time without adjusting pH value of waste water
Short, materials are few, and treatment effeciency is high.
Specific embodiment
The invention will be further described in conjunction with the embodiments, it should illustrate to be, following the description is merely to explain this hair
It is bright, its content is not defined.
The calculation method of Methylene Blue removal rate of the present invention are as follows: measure methylene with ultraviolet specrophotometer at 664nm
The absorbance of base indigo plant waste water finds out the removal of methylene blue by the variation of methylene blue waste water absorbance before and after oxidation reaction
Rate.Calculation formula are as follows: removal rate (%)=(A0- A)/A0× 100%, in formula, A0For the absorbance before methylene blue waste water reaction
Value, A are the absorbance value after reaction.
Embodiment 1
2.84g sodium metasilicate and 1.98g manganese chloride is taken to be dissolved in 50mL deionized water respectively, it is under stirring, sodium metasilicate is molten
Liquid is slowly added into metal salt solution, forms mixed solution, is persistently stirred 15 minutes at room temperature, and centrifugation is clear with deionized water
It washes 3 times, is dried at 60 DEG C, obtain taupe manganous silicate powder.
It takes 10mg manganous silicate to be dissolved in the methylene blue waste water that 95mL concentration is 50mg/L, 5mL is added under stirring
The hydrogen peroxide that mass fraction is 30% is kept for 60 minutes, and the removal rate of methylene blue is up to 96%.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
Member, under the premise of not departing from the method for the present invention, can also make several improvements and modifications, these improvements and modifications also should be regarded as
Protection scope of the present invention.
