Abstract

The invention provides an adsorbent for industrial sewage treatment and a preparation method thereof. The method comprises the steps: firstly, modifying a composite halloysite nanotube through N-(beta-aminoethyl)-gamma-aminopropyltriethoxysilane, and thus obtaining a modified halloysite nanotube; modifying edible mushroom dregs by using epoxy chloropropane to obtain epoxidized mushroom dregs; then mixing the modified halloysite nanotube with epoxidized mushroom dregs for reaction, and grafting by using starch to obtain an intermediate product; and finally, mixing the intermediate product with vinylidene fluoride and 2-acrylamide-2-methylpropanesulfonic acid, and carrying out a polymerization reaction to obtain the adsorbent for industrial sewage treatment, wherein the adsorbent for industrial sewage treatment has an excellent adsorption treatment effect on industrial sewage, high adsorption capacity, good reproducibility and recyclability, and the industrial sewage treatment cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an adsorbent for industrial sewage treatment and a preparation method thereof. Background technique [0002] With the acceleration of urbanization and the rapid development of industry and agriculture, most cities in my country have serious water pollution problems. A large amount of untreated municipal waste, industrial and domestic sewage, and atmospheric deposition are continuously discharged into water bodies. In particular, the wastewater produced in industrial production contains a large amount of industrial production materials, intermediate products and products, as well as pollutants produced in the production process. If it is discharged directly, it will inevitably pollute the environment seriously and threaten human health and safety. [0003] The pollutants in industrial sewage are mainly ammonia nitrogen, heavy metals and other substances. Ammonia nitrogen...
