Problems solved by technology

However, ordinary activated carbon has the disadvantages of low specific surface area, poor adsorption performance, easy saturation of adsorbent, low adsorption efficiency, and inconvenient separation. The existing activated carbon filter element basically does not effectively treat activated carbon, which will cause pollution and seriously affect Adsorption efficiency

Embodiment Construction

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

[0018] An anti-pollution activated carbon adsorbent, made of the following raw materials in parts by weight (kg): sludge 140, corn stalks 15, peanut shells 18, zinc chloride 43, magnesium silicate 15, zirconia 8, cetyl Trimethylammonium bromide 3, polyvinyl alcohol 3, ZSM-11 molecular sieve 9, calcium silicate 7, aluminum oxide 6, appropriate amount of distilled water;

[0019] A kind of anti-pollution activated carbon adsorbent 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;

Abstract

The invention discloses an anti-pollution active carbon adsorbent, which is characterized by comprising 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, 8-11 of ZSM-11 molecular sieve, 6-8 of calcium silicate, 5-6 of alumina, and a proper amount of distilled water. Raw materials, of the ZSM-11 molecular sieve, calcium silicate, and alumina, added in the adsorbent are non-toxic, high in adsorptive property, and good in interchangeability and fire resistance, and the adsorptive property of sludge active carbon is improved. The prepared adsorbent is of anti-pollution, is high in adsorption capacity, wide in adsorption range, and fast in adsorption and separation speed, and is recyclable. The adsorption process has no secondary pollution, so that the active carbon adsorbent is worthy of popularization.

Description

technical field [0001] The invention relates to the field of adsorbents, in particular to an anti-pollution 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 adsorption capacity....
