Abstract

The invention discloses a preparation method of a composite adsorbing material of industrial wastewater heavy metal ions. The composite adsorbing material comprises a carrier, functional components and catalytic components. The preparation method comprises the steps of mixing and ball-milling all components of the carrier into a corresponding grain size and mixing, mixing and preparing all components of the functional components into a solution, preparing all components in the catalytic components into suspension liquid, selecting all components in parts by weight, mixing, diluting and stirring to obtain slurry, drying and then crashing. The composite adsorbing material provided by the invention has the advantages that the adsorbing effect is good, the cost is low and the preparation is simple.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a preparation method of a composite adsorption material for industrial waste water heavy metal ions. Background technique [0002] With the advancement of the industrialization process, my country's manufacturing industry has achieved rapid development, but my country's industrialization development is still in its infancy, and quite a few enterprises' production is extensive and heavily polluting, such as dyes, medicines, chemicals, smelting, electroplating, etc. A large amount of wastewater is produced during the production process. If the environmental protection technology and regulatory measures are not in place, the above-mentioned wastewater is discharged into the environment, and the high concentration of organic matter and heavy metal ions contained in it will bring serious disasters to humans and the ecological environment. Therefore, Strict treatment m...
