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.
