Active carbon adsorbent with excellent dedusting sterilizing performance

Abstract

The invention discloses an active carbon adsorbent with excellent dedusting sterilizing performance. The active carbon adsorbent is characterized by preparing from the following raw materials, by weight part: 100-150 of sludge, 13-17 of cornstalk, 15-24 of peanut hull, 30-50 of zinc chloride, 13-16 of magnesium silicate, 6-9 of zirconia, 2-4 of cetyltrimethylammonium bromide, 2-3 of polyvinyl alcohol, 4-7 of silver oxide, 5-7 of amorphous aluminium silicate, 3-5 of oxidized graphene, and a proper amount of distilled water. Raw materials, of silver oxide, amorphous aluminium silicate, and oxidized graphene, added in the adsorbent have a synergistic effect on one another; sterilizing activity, strength, and toughness of the sludge active carbon are greatly promoted; the specific surface area of the adsorbent is improved; and the absorbing channel is enlarged. According to the invention, the adsorbent is good in dedusting performance, sterilizing activity, anti-corrosive property, and cycle use effect; the preparation technology is simple; and the source of materials is rich, so that the adsorbent is worthy of popularization.

Description

technical field [0001] The invention relates to the field of adsorbents, in particular to an activated carbon adsorbent with excellent dust removal and sterilization effects 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 surfa...
