Description
Technical field
The present invention relates to Technology of Sewage field, and in particular to a kind of laccase and modified dicyandiamine formal composite decoloring agent.
Background technology
Dyeing waste water has that colourity is big, organic concentration is high, alkaline strong, water quality and quantity change greatly the features such as, textile enterprise
Based on the biochemical treatment for using mostly, the handling process supplemented by materializing strategy, the effect of biological treatment organics removal is good, takes
With low but not ideal enough to the removal of colourity；Physico-chemical process decolourizes quickly, efficiently, but low to the removal effect of organic matter, and treatment
It is costly.Waste water disposal facility to after running a period of time, easily occur that biodegradability is poor, sludge loss seriously, the residence time
Short, hydrolysis biochemical stage efficiency declines or even loses activity, and then causes materializing strategy stage load to be strengthened, and continues to increase wadding
The usage amount of decolouring medicament is coagulated so as to poisonous metal content increases in causing mud, secondary pollution can be caused again, thus develop
The efficient decolorising agent of low toxicity is significant.
The content of the invention
It is an object of the present invention to be directed to prior art, there is provided a kind of laccase and modified dicyandiamine formal composite decoloration
Agent.
To achieve the above object, the present invention takes following technical scheme：A kind of laccase is combined with modified dicyandiamine formal
Decolorising agent, it is made up of the following raw material of mass parts：20~50 parts of modified dicyandiamine formal polymer, 1~5 part of laccase, polymerization
1~3 part of ferric sulfate, 1~3 part of diatomite, 1~5 part of activated carbon, 1~5 part of calcium sulfate, 2~6 parts of aluminum sulfate.
Wherein, the modifying agent of described modified dicyandiamine formal polymer is ethylenediamine or N- dihydroxy aniline or 2- miaows
Oxazolidone.
Further, the preparation method of described modified dicyandiamine formal is：It is 1 by mass ratio：2：3：2：Dicyan
Diamines, formaldehyde, ammonium chloride, modifying agent are placed in the flask for installing reflux condensing tube, and heating water bath to constant temperature after 50 DEG C is stirred
20min, is further continued for being heated to 90 DEG C of reaction 4h and obtains final product modified dicyandiamine formal polymer.
Through ethylenediamine or N- dihydroxy aniline or the modified dicyandiamide formal polymer of 2- imidazolidinones in the present invention
Molecular weight is improved, and during treatment waste water, the coagulated particles of formation are big, and sinking speed is fast slowly, and its decoloration performance and decolorization rate are obtained
Improve, there is good effect to treatment of dyeing wastewater.
In the present invention, bodied ferric sulfate, calcium sulfate, aluminum sulfate are flocculant aid, and activated carbon is porous adsorbent, diatom
Soil is the carrier of laccase, and laccase can degrade the pollutant in sewage, play biological prosthetic effect.
The beneficial effects of the invention are as follows：
1st, be combined for laccase and modified dicyandiamine formal composite decoloring agent by the present invention, the modified dicyandiamide of the pollutant in waste water
After formal and bodied ferric sulfate, calcium sulfate, aluminum sulfate, charcoal absorption flocculation sediment, then by laccase decomposing pollutant, both
Use cooperatively, improve decoloration performance and decolorization rate, moreover it is possible to fundamentally remove pollutant, good decolorizing effect of the present invention, flocculation
Effect is strong, and stability is high；
2nd, modified dicyandiamine formal of the invention is modified, and molecular weight is big, and settling velocity is fast, charge neutrality efficiency high, and volume sweeps dirt
Dye thing effect is good, coordinates with bodied ferric sulfate, calcium sulfate, aluminum sulfate, activated carbon, improves decoloration performance and decolorization rate.
