Environment-friendly degrading and adsorbing material for printing and dyeing industry wastewater

Abstract

The invention discloses an environment-friendly degrading and adsorbing material for printing and dyeing industry wastewater, which is characterized by comprising the following components in parts by weight: 19-23 parts of gypsum powder, 1-3 parts of floating bead, 5-7 parts of core-shell high molecular polymer emulsion, 1-3 parts of nano oxide, 5-10 parts of filler, 1 part of antimicrobial micropowder, 1-3 parts of nano particle inorganic material, 2-7 parts of calcium carbonate, 1-6 parts of calcium sulfate, 1-4 parts of kieselguhr, 2-4 parts of acrylic fiber, 1-7 parts of polypropenyl ester fiber, 3-9 parts of ethanol, 8-15 parts of ferric oxide and 4-11 parts of phosphite antioxidant. The material has high adsorptivity, can adsorb azo dye molecules in azo dye wastewater into small networks, achieves the effect of efficiently absorbing azo dye molecules in wastewater, and has favorable treatment effect. The dye waste after adsorption can be used as a pigment for plastics and building materials.

Description

technical field [0001] The invention relates to an environmentally friendly degradable adsorption material for waste water in the printing and dyeing industry. 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 ch...
