Removable and reusable activated carbon adsorbent

Abstract

The invention discloses a removable and reusable activated carbon adsorbent. The removable and reusable activated carbon adsorbent is characterized by being prepared from the following raw materials in parts by weight: 100 to 150 parts of sludge, 13 to 17 parts of a maize straw, 15 to 24 parts of a peanut shell, 10 to 15 parts of manganese ore powder, 30 to 50 parts of zinc chloride, 13 to 16 parts of magnesium silicate, 5 to 8 parts of silicon dioxide, 3 to 5 parts of polyvinyl alcohol, 3 to 5 parts of polyacrylamide, 5 to 6 parts of ceramic fiber, 5 to 6 parts of ferrous sulfate, 8 to 11 parts of diatom ooze and an appropriate amount of distilled water. The magnetic performance, the strength and the adsorbability of the adsorbent are improved by the addition of the ferrous sulfate, the ceramic fiber and the diatom ooze, so that sludge activated carbon is easy to separate, high in reusability and good in abrasion resistance, and powder is not easy to fall. Compared with a conventional adsorbent, the prepared adsorbent has the characteristics of being easy to separate, reusable, non-toxic and environment-friendly, and facilitating environment protection; the adsorbent, serving as an air conditioner filter element material, is wide in application prospect.

Description

technical field [0001] The invention relates to the field of adsorbents, in particular to an easily removed and reusable activated carbon adsorbent 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 area and strong adsorpt...

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.
