Method for extracting micron-sized iron oxides based on sinter machine head dust, preparation method and application of iron-carbon composite material

Abstract

The application relates to a method for extracting micron-sized iron oxides based on sintering machine head ash, a preparation method and application of iron-carbon composite materials, and belongs to the technical field of solid waste resource utilization and wastewater anaerobic biological treatment.The micron-sized functional materials of iron oxides in the sintering machine head ash are extracted through a simple water washing-acid washing process, and are applied to the field of wastewater anaerobic digestion with high added value, the use of the solid waste components is completely changed, high-value resource utilization of the sintering machine head ash is realized, and the problem of low utilization way of the insoluble components of the sintering machine head ash is solved.The micron-sized iron oxides and the iron-carbon composite materials thereof exhibit excellent catalytic reinforcement effect, the removal efficiency of organic matters is obviously improved, and the anaerobic treatment efficiency of refractory high-organic wastewater is obviously strengthened.
