Environmentally friendly and energy-saving activated carbon adsorbent with long service life

Abstract

The invention discloses an environmentally friendly and energy-saving activated carbon adsorbent with long service life. The invention is characterized in that the activated carbon adsorbent is prepared from the following raw materials, by weight, 100-150 parts of sludge, 13-17 parts of corn straw, 15-24 parts of peanut shell, 10-15 parts of manganese ore powder, 30-50 parts of zinc chloride, 13-16 parts of magnesium silicate, 5-8 parts of silicon dioxide, 3-5 parts of polyvinyl alcohol, 3-5 parts of polyacrylamide, 4-6 parts of bamboo fiber, 7-9 parts of nanometer silicon powder, 8-10 parts of expanded perlite and a proper amount of distilled water. As the bamboo fiber added has natural bactericidal, bacteriostatic and anti-UV properties, the activated carbon adsorbent is nontoxic and environmentally friendly; the silicon powder added enhances adsorbability and bactericidal property; the expanded perlite added increases adsorption area and enhances heat resistance of the adsorbent. The adsorbent provided by the invention has fresh and fragrant smell, is environmentally friendly and energy-saving, has long service life, has a good adsorption effect, has high reuse efficiency and has a wide application prospect.

Description

technical field [0001] The invention relates to the field of adsorbents, in particular to an environmentally friendly, energy-saving and long-lasting 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 su...

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.
