Preparation method and application of iron ore-carrier water treatment material

Abstract

The invention relates to a preparation method and application of an iron ore-carrier water treatment material, and belongs to the technical field of water treatment and water environment remediation, the preparation method comprises the following steps: grinding an iron ore material with a grinding medium to obtain iron ore powder, and storing the iron ore powder in a nitrogen environment for later use; the method comprises the following steps: mixing iron ore powder with a carrier supporting material, adding water, stirring and filtering to obtain a product A; the product A is subjected to heating, heat preservation, cooling, crushing and screening in the nitrogen atmosphere, and then the iron ore-carrier water treatment material is obtained. The water treatment material prepared by using reduction components such as iron, aluminum and sulfur in an iron ore material and combining with a carrier supporting material through a specific heat treatment process has better physicochemical characteristics, provides a good habitat for microorganisms, and not only promotes microbial metabolism to degrade organic pollutants, but also improves the water treatment efficiency by combining with a biofilm formation technology. And pollutants are purified through a chemical reduction effect, so that the removal efficiency of various pollutants is improved.
