Embodiment Construction

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

[0018] A modified activated carbon air purifier, made of the following raw materials in parts by weight (kg): sludge 130, corn stalks 16, peanut shells 21, zinc chloride 46, magnesium silicate 15, zirconia 8, hexadecane Trimethyl ammonium bromide 3, polyvinyl alcohol 3, boron fiber 9, dimethyl silicone oil 2, polypropylene powder 8, distilled water in proper amount;

[0019] A kind of modified activated carbon air cleaner of the present invention is made by 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 weight, and after cooling, crush them into 1-5mm sizes for later use;

[0022] (3) Mix...

Abstract

The invention discloses a modified active carbon air purifier which 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, 30-50 parts of zinc chloride, 13-16 parts of magnesium silicate, 6-9 parts of zirconium oxide, 2-4 parts of hexadecyl trimethyl ammonium bromide, 2-3 parts of polyvinyl alcohol, 7-11 parts of boron fibers, 1-3 parts of simethicone, 5-9 parts of polypropylene powder and a proper amount of distilled water. Under the synergistic effect of the added boron fibers, the simethicone and the polypropylene powder, the toughness, the heat resistance, the adsorbability and the intensity of the adsorbent are improved; the abrasion resistance is improved; dispersion is difficult, and the service life is long; the preparation technology is simple, stable in performance and low in cost and has potential in industrial production.

Description

technical field [0001] The invention relates to the field of adsorbents, in particular to a modified activated carbon air purifier 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 adsorption capacity. In...
