Abstract
The present invention relates to a kind of electroplating wastewater decoloration agent prescriptions, it is characterised in that：It includes following material component by weight：75~95 parts of wood vinegar, 25~45 parts of sodium tripolyphosphate, 15~35 parts of furfuryl alcohol, 75~95 parts of aluminium chloride, 25~45 parts of magnesia, surfactant accounts for 3-38 parts, 7-15 parts of zinc oxide, 10-20 parts of sodium carbonate；The decolorising agent used in the present invention, has broad spectrum activity, and the waste liquid after wastewater treatment avoids waste liquid brightness reversion.
Description
Technical field
The present invention relates to electroplating wastewater processing field more particularly to a kind of electroplating wastewater decoloration agent prescriptions.
Background technique
Existing coagulating waste water decolorising agent can generally be divided into inorganic and organic two major classes, organic decolorising agent specificity compared with
By force, higher cost, and dosage controls the bad raising that can also cause to be discharged COD；Inorganic type coagulation decoloration agent is coagulation
The developing direction of decolorising agent, serial coagulation decoloration agent inorganic at present mainly have：PAC, PFS, PFC, ferrous sulfate, Polyferric Sulfate aluminium, gather
Alumina silicate etc..What effect was preferable and generally the least expensive in inorganic coagulation decoloration agent series products is ferrous sulfate, but its there is also
Alkali charge, sludge output are larger, water outlet is easy the shortcomings that turning yellow, and in addition also have to process using the metal killing pickle of steel industry and mix
Solidifying decolorising agent, but its shortcomings that there are acidity is low, easy brightness reversion.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of electroplating wastewater decoloration agent prescriptions, are able to solve general wide spectrum
Property it is poor, waste liquid decoloration after be easy yellowing the problem of.
In order to solve the above technical problems, the technical scheme is that：A kind of electroplating wastewater decoloration agent prescription, innovative point
It is：It includes following material component by weight：75~95 parts of wood vinegar, 25~45 parts of sodium tripolyphosphate, furfuryl alcohol 15~35
Part, 75~95 parts of aluminium chloride, 25~45 parts of magnesia, surfactant accounts for 3-38 parts, 7-15 parts of zinc oxide, 10-20 parts of sodium carbonate.
The advantage of the invention is that：
1）The decolorising agent used in the present invention, has broad spectrum activity, and the waste liquid after wastewater treatment avoids waste liquid brightness reversion.
Specific embodiment
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among the embodiment described range.
Embodiment 1：
A kind of electroplating wastewater decoloration agent prescription, it includes following material component by weight：75 parts of wood vinegar, sodium tripolyphosphate 25
Part, 15 parts of furfuryl alcohol, 75 parts of aluminium chloride, 25 parts of magnesia, surfactant accounts for 3 parts, 7 parts of zinc oxide, 10 parts of sodium carbonate.
Embodiment 2：
A kind of electroplating wastewater decoloration agent prescription, it includes following material component by weight：85 parts of wood vinegar, sodium tripolyphosphate 35
Part, 25 parts of furfuryl alcohol, 85 parts of aluminium chloride, 35 parts of magnesia, surfactant accounts for 20 parts, 11 parts of zinc oxide, 15 parts of sodium carbonate.
Embodiment 3：
A kind of electroplating wastewater decoloration agent prescription, it includes following material component by weight：95 parts of wood vinegar, sodium tripolyphosphate 45
Part, 35 parts of furfuryl alcohol, 95 parts of aluminium chloride, 45 parts of magnesia, surfactant accounts for 38 parts, 15 parts of zinc oxide, 20 parts of sodium carbonate.
It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, above-described embodiment and explanation
It is merely illustrated the principles of the invention described in book, without departing from the spirit and scope of the present invention, the present invention also has
Various changes and modifications, these changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention
It is defined by the appending claims and its equivalent thereof.
