Abstract

The invention relates to a composite active carbon material and a preparation method thereof. The composite active carbon material is prepared from the following raw materials in percentage by mass: 50-60% of powdery active carbon, 25-35% of active carbon fiber, 10-15% of chopped fiber and 2-5% of arcylic glue, wherein the powdery active carbon is sargassum horneri active carbon, the length of thechopped fiber is 35-50 mm, and the total weight percentage content of the components is 100%. The preparation method comprises the steps that active carbon fiber, sargassum horneri active carbon, chopped fiber and acrylic glue are weighed, a mixed raw material is obtained, and the mixed raw material and water are uniformly mixed; the mixture is produced to be net and sized on a paper making machine at a time, and the active carbon fiber composite material is formed. The composite active carbon material has the enlarged specific surface area, high adsorption capability and wide range of organic matter adsorption, and also has the good adsorption and purification ability on wastewater containing Cr (VI). The preparation method of the composite active carbon material is simple and practical,can be applied to large-scale production, and can be used in the field of treatment of wastewater.

Description

technical field [0001] The invention belongs to the technical field of sewage purification, and in particular relates to a composite activated carbon material and a preparation method. Background technique [0002] Due to its large specific surface area and strong adsorption, activated carbon has broad application prospects in the field of environmental protection and has received widespread attention. The raw materials for the preparation of activated carbon can be divided into two categories: plant and mineral. In recent years, the research on the preparation of activated carbon from seaweed, a huge plant population, has gradually emerged. [0003] Activated carbon fiber is an activated carbon-containing fiber. A certain carbon-containing fiber is activated at high temperature to produce nano-scale pores on the surface, increase the specific surface area, and change its physical and chemical properties. Activated carbon fiber has a developed specific surface area and nar...
