Efficient adsorption composite material for azo dye wastewater

Abstract

A disclosed efficient adsorption composite material for azo dye wastewater comprises the following substances in parts by weight: 10-32 parts of acrylic high-molecular water-absorption resin, 5-9 parts of nitric acid, 4-6 parts of sodium hydroxide, 3-7 parts of potassium hydroxide, 1-8 parts of calcium hydroxide, 1-3 parts of a nanometer-level particle inorganic material, 2-7 parts of calcium carbonate, 1-6 parts of calcium sulfate, 1-4 parts of diatomite, 2-4 parts of acrylic fiber, 1-7 parts of polyacrylate fiber, 3-9 parts of ethanol, 8-15 parts of ferric oxide, 4-11 parts of a phosphite anti-oxidant. The beneficial effects comprise that the efficient adsorption composite material is high in adsorption property, is capable of adsorbing azo dye molecules in azo dye wastewater into a tiny network to reach the effect of efficiently absorbing azo dye molecules in wastewater, and is good in processing effect; and also dye wastes subjected to adsorption can be used as a pigment of plastic and building materials.

Description

technical field [0001] The invention relates to a high-efficiency adsorption composite material for azo dye wastewater. Background technique [0002] Azo dye industrial wastewater is widely distributed in my country and has many types. Scientific research has confirmed that most of the azo dye wastewater has high concentration of organic matter and large chroma, often with benzene ring or tea ring, and has high oxidation resistance and light resistance. And high chemical stability, become one of the most difficult industrial wastewater. At present, the treatment methods at home and abroad generally include activated carbon adsorption method, biodegradation method, modified bentonite adsorption method and photocatalyst degradation method, etc. The above methods generally have the disadvantages of large consumption of oxidant, long treatment time, and high cost. Nano-dispersible CMC-acrylic polymer water-absorbing resin, the molecular chain length of which is several nanometer...
