Embodiment Construction

[0010] A modified activated carbon for removing organic pollutants, made of the following raw materials in parts by weight: activated carbon 85 polysaccharides 7 gum arabic 3, sodium alginate 1, sepiolite 32, zeolite 13, modified attapulgite 9, 25 Proper amount of hydrochloric acid, appropriate amount of water;

[0011] The modified attapulgite is made of the following raw materials in parts by weight (kg): attapulgite 110, jade powder 3, kaolin 9, crosslinking agent TAC 1.5, aluminum hydroxide 9, zinc stearate 2, borax 1 , titanium sulfate 16, urotropine 2, lanthanum oxide 1, chromium oxide 3, morpholine 1, and an appropriate amount of water; the preparation method is to send attapulgite, jade powder, and kaolin into a calciner, and calcined at 880°C for 2 hour, take it out, sprinkle with cross-linking agent TAC, then put it into appropriate amount of water for grinding, adjust the pH value of the grinding liquid to 4, grind for 1.5 hours to obtain a 120-mesh slurry, then adj...

Abstract

Modified activated carbon for removing organic pollutants is prepared from the following raw materials: by weight, 80-90 parts of activated carbon, 6-8 parts of chitosan, 3-4 parts of Arabic gum, 1-2 parts of sodium alginate, 30-34 parts of sepiolite, 12-14 parts of zeolite, 8-10 parts of modified attapulgite and a proper amount of 20-25% hydrochloric acid and water. The modified activated carbon prepared by the method is used as an adsorbent, at the same time, the sepiolite, the zeolite and other substances with strong adsorption ability are added into the modified activated carbon, and the modified activated carbon can be used for removing the organic pollutants in a water treatment process, has the advantages of high purification capacity and long service life, and especially can solve the problem that water treatment methods in the prior art have poor operability on water polluted by endocrine disruptors of high concentration of phenols.

Description

technical field [0001] The invention relates to a modification method of non-metallic ore, in particular to a modified activated carbon for removing organic pollutants and a preparation method thereof. Background technique [0002] With the development of science and technology and the gradual construction of modern industries, various chemicals have been developed and utilized, which has brought convenience to people's lives. The problem. [0003] At present, the pollutants in the air are mainly the gas produced by industrial fuel combustion, automobile exhaust, and toxic and harmful gases produced in production. Water pollution is mainly due to the fact that the sewage discharged from industrial production contains a large amount of toxic substances, and the sewage produced in people's daily life produces many harmful substances. There are many times in people’s lives that people need to remove toxins. For example, there are many bacteria and toxins on the filter screen ...
