Abstract
The invention provides an environment-friendly composite decoloring agent. The decoloring agent is composed of the following raw materials in parts by weight: 3 to 12 parts of polyacrylamide, 2 to 10 parts of lignin, 3 to 5 parts of silicon tetrachloride, 5 to 10 parts of nano silicon dioxide, 3 to 8 parts of aluminum hydroxide, 2 to 7 parts of sodium percarbonate, 5 to 15 parts of absorbent, and 20 to 50 parts of water. The provided decoloring agent can achieve an excellent decoloring effect without the assistance of other reagents, thus the investment is reduced, at the same time, the decoloring effect is excellent, the technology process is shortened, the preparation is simple, the operation is convenient, and the decoloring agent is safe and pollution-free and will not generate secondary pollution to the environment.
Description
Technical field
The present invention relates to a kind of discoloring agent, be specifically related to a kind of environment-friendly type composite decoloring agent.
Background technology
In trade effluent, the textile printing and dyeing wastewater, leather coloring waste water, paper waste etc. of high chroma are all because adding various dyestuff and containing the material of chromophoric group and cause chroma in waste water high in water, extremely difficult by direct biochemical degradation process, first after coagulation decoloration or coagulation air-float pre-treatment decolouring, just must can enter subsequent biochemical treatment system.General polymeric aluminum, polymeric iron or ferro-aluminum composite water purifying agent all do not reach good decolorizing effect, and especially when the active dye wastewater that process wetting ability is strong, aluminium system and iron series water purifier are almost helpless.Therefore, the improvement of dyeing waste-water, particularly desolventing technology are a great problems being badly in need of in the outer wastewater treatment of Now Domestic solving.
Existing market also has a large amount of discoloring agents in use, but it is rich in many drawbacks, contain heavy metal element poisonous impurities as some discoloring agent and cannot recycle after bleaching agent bleaching, to environment structure harm, and partial decolorization agent needs severally to coordinate simultaneously, competence exertion decolorizing effect, like this, add production cost, and, technical process is long, operates also more complicated.
Therefore, for the problems referred to above, the present invention proposes a kind of new technical scheme.
Summary of the invention
The object of this invention is to provide a kind of good decolorizing effect, environment-friendly type composite decoloring agent simple to operate.
The present invention is achieved through the following technical solutions:
A kind of environment-friendly type composite decoloring agent, comprises the raw material composition of following parts by weight:
Polyacrylamide 3 ~ 12 parts;
2 ~ 10 parts, xylogen;
Silicon tetrachloride 3 ~ 5 parts;
Nano silicon 5 ~ 10 parts;
3 ~ 8 parts, aluminium hydroxide;
SPC-D 2 ~ 7 parts;
5 ~ 15 parts, sorbent material;
20 ~ 50 parts, water.
Further, described oxygen aluminum oxide is aluminum hydroxide gel.
Further, described polyacrylamide can substitute with sodium polyacrylate or calcium polyacrylate (CPA).
Further, described sorbent material is gac, white carbon black, wilkinite wherein one or more mixture.
The invention has the beneficial effects as follows: discoloring agent proposed by the invention has excellent decolorizing effect, do not need other medicament as auxiliary, thus reduce cost input, meanwhile, decolorizing effect is high, shortens technical process, and preparation is simple, easy to operate, safety non-pollution, can not produce secondary pollution to environment.
