Active carbon adsorbent with good effects of removing formaldehyde and removing odors

Abstract

The invention discloses an active carbon adsorbent with good effects of removing formaldehyde and removing odors. The active carbon adsorbent is characterized by being prepared from the following raw materials in parts by weight: 100-150 parts of sludge, 13-17 parts of corn straws, 15-24 parts of peanut shells, 10-15 parts of manganese ore powder, 30-50 parts of zinc oxide, 13-16 parts of magnesium silicate, 5-8 parts of silicon dioxide, 3-5 parts of polyvinyl alcohol, 3-5 parts of polyacrylamide, 12-15 parts of tea leaf dreg powder, 8-12 parts of calcium oxide, 6-8 parts of carbon fibers and proper amount of distilled water. According to the active carbon adsorbent, the tea leaf dreg powder, calcium oxide and the carbon fibers are added so that the properties of sterilizing, odor removal, acid and alkali corrosion resistance, high strength and high adsorption capability of sludge active carbon are extremely promoted; the active carbon adsorbent has high formaldehyde removing efficiency, can be used for deodorizing and removing peculiar smell, and is good in moisture absorption; by using the active carbon adsorbent, the air quality is good; and the active carbon adsorbent is good for body health of people and is worthy of popularization.

Description

technical field [0001] The invention relates to the field of adsorbents, in particular to an activated carbon adsorbent with good effects of removing formaldehyde and odor and a preparation method thereof. Background technique [0002] With the acceleration of urbanization, the increase of urban population and the strengthening of environmental protection awareness, the discharge of urban industrial wastewater and domestic sewage is increasing, the rate of urban sewage treatment is also increasing year by year, and the sludge generation rate of sewage plants is also increasing sharply. The sludge of the sewage treatment plant has a high water content, a large amount of organic matter, toxic and harmful substances, and semi-dry solid waste with complex rheology. It has a large capacity, is easily corrupted, unstable, and has a bad smell. cause serious environmental pollution. Activated carbon is a porous adsorption material with rich pore structure, high specific surface ar...

Problems solved by technology

At present, there are mainly chemical, biological, and photocatalyst products on the market. These products are expensive and have certain restrictions on use conditions. Activated carbon has the advantages of affordable price, convenient use, no pollution, no side effects, and ideal use effects. However, Ordinary activated carbon adsorbents are easy to be saturated, easy to fall powder and scattered, the use time is not long, and the separation is not easy, and the adsorption efficiency is low.
