Embodiment Construction

[0011] A modified activated carbon water purifier, made of the following raw materials in parts by weight (kg): activated carbon 110, magnesium nitride powder 5, bentonite 7, kaolin 7, diatomite 7, zeolite 5, trichloroisocyanurate Acid 3, boric acid 18, citric acid 9, modified diatomaceous earth 4, appropriate amount of water;

[0012] The modified diatomite is made of the following raw materials in parts by weight (kg): diatomite 125, sepiolite 11, nano-carbon 1.5, clove oil 2.5 ascorbic acid 1.5, sodium alginate 2.6, kaolin 33, gynostemma powder 3.5 The preparation method is to put diatomite and sepiolite into a calciner and calcinate at 550°C for 3.5 hours, take it out, soak it in 14% hydrochloric acid solution for 4 hours, filter it out, wash it repeatedly with clear water, and dry it. Add water, at the same time, add nano-carbon, ascorbic acid, kaolin, grind to obtain slurry, spray dry, mix other remaining ingredients with dry powder, grind and disperse evenly.

Abstract

The invention relates to a modified activated carbon purifying agent which is prepared from the following raw materials in parts by weight: 110-120 parts of activated carbon, 3-6 parts of magnesium nitride powder, 5-8 parts of bentonite, 5-8 parts of kaolin, 5-8 parts of kieselguhr, 4-6 parts of zeolite, 2-4 parts of trichloroisocyanuric acid, 15-20 parts of boric acid, 8-10 parts of citric acid, 4-5 parts of modified kieselguhr and right amount of water. The bentonite and other natural stone materials are utilized to modify the activated carbon, so that the activated carbon has the effects of microbial resistance, decolorization, flocculation, ion exchange, beneficial microelement release and the like; the iodine sorption value and methylene blue adsorptive value of the activated carbon purifying agent exceed the standard values of National Wood Water Purification Activated Carbon Grade 1; and the modified activated carbon purifying agent is simple and effective, and has the advantages of wide raw material sources, low cost, low corrosivity and small environmental pollution.

Description

technical field [0001] The invention relates to the field of modified functional materials, in particular to a modified activated carbon water purifier 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 of air condition...
