Problems solved by technology

However, due to repeated desorption in acid-base solutions, its adsorption capacity will decrease due to the increase in the number of uses until the adsorption material fails and becomes unusable.
At present, the magnetic nano-adsorption materials prepared on the market will reduce their adsorption capacity by 30-60% after being used for 6-10 times. The low recyclability of the material limits its industrial application
[0004] Chinese patent CN104475040 A discloses a modified magnetic nano-adsorption material, the modified magnetic nano-adsorption material is Fe 3 o 4 Nanoparticles as carriers, Fe 3 o 4 Nanoparticles co

Abstract

The invention relates to the technical field of wastewater purification, in particular to a recycled water treatment adsorption material and a preparation method thereof. The adsorption material is prepared by: compounding activated carbon, a methyl methacrylate monomer, an initiator, a cross-linking agent and the like to form activated carbon composite polymethyl methacrylate microspheres, then carrying out silicon dioxide sputtering on the activated carbon composite polymethyl methacrylate microspheres, then carrying out surface amination treatment, and finally, carrying out magnetization modification on the surface aminated microspheres. The cyclic regeneration water treatment adsorption material prepared by the invention can still keep stable adsorption capacity after multiple times of adsorption-desorption, and has excellent cyclic regeneration performance and strong industrial practicability.

Description

technical field [0001] The invention relates to the technical field of wastewater purification, in particular to a recycled water treatment adsorption material and a preparation method thereof. Background technique [0002] Synthetic dyes are divided into nitro, azo, anthraquinone, indigo, aromatic methane, etc. according to their chemical structure. According to the application method, it is divided into acidic, alkaline, direct, mordant, vulcanization, reduction, ice dyeing, dispersion, active and so on. Due to the increasing popularity of synthetic dyes in recent years, all kinds of synthetic dyes have been widely used in printing and dyeing, papermaking, leather, cosmetics and food industries, and the discharge of dye wastewater is also becoming more and more popular. A large amount of dye wastewater will not only affect the self of aquatic organisms purify. Among synthetic dyes, azo dyes are the most harmful. When azo dyes decompose, they will produce a large amount o...
