Embodiment Construction

[0017] The present invention will be described in detail below through specific examples.

[0018] An activated carbon adsorbent with excellent dust removal and sterilization effects, made of the following raw materials in parts by weight (kg): sludge 130, corn stalks 16, peanut shells 18, zinc chloride 42, magnesium silicate 15, zirconia 8, ten Hexaalkyltrimethylammonium bromide 3, polyvinyl alcohol 3, silver oxide 6, amorphous aluminum silicate 6, graphene oxide 4, appropriate amount of distilled water;

[0019] A kind of activated carbon adsorbent with good dedusting and sterilizing effect of the present invention is made by the following specific steps:

[0020] (1) Air-dry the sludge from the sewage treatment plant under natural conditions, and then dry it in an oven at 110°C for 18 hours. After cooling, grind it into sludge particles with a particle size of 1-3mm for use;

[0021] (2) Dry the corn stalks and peanut shells in an oven at 80°C until they reach a constant w...

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...
