Composite absorbent material for waste gas treatment

Abstract

The invention discloses a composite absorbent material for waste gas treatment. The composite absorbent material is prepared from a carrier, a functional component and a catalytic component, wherein the carrier is prepared from a mixture of bentonite and kieselguhr, activated carbon, zeolite, attapulgite, a mixture of wood chips, sawdust and crop straws, CMC (Carboxy Methylated Cellulose) and the like; the functional component is prepared from ferrous sulfate, potassium permanganate, and potassium sulfate / magnesium chloride; the catalytic component is prepared from nano-water and ferric oxide, and nanometer titania; the composite absorbent material disclosed by the invention has the advantages of good adsorbing effect, low cost, and simple preparation.

Description

technical field

[0001] The invention belongs to the field of environmental protection, and in particular relates to a composite adsorption material for waste gas treatment. Background technique

[0002] With the advancement of industrialization, my country's manufacturing industry has achieved rapid development, but my country's industrialization development is still in its infancy, and the production of quite a few enterprises is extensive and heavily polluting, such as factories and mines, pharmaceuticals, chemicals, smelting, and other production A large amount of waste gas is produced during the process. In addition to a large amount of soot solid particles, the above-mentioned waste gas also contains heavy metal ions and macromolecular organic substances that seriously affect human health. If the environmental protection technology and regulatory measures are not in place, the above-mentioned waste gas will be discharged into the atmosphere. In this process, it will bring...
