Abstract

The invention discloses high-efficient water-purifying activated carbon and a preparation method thereof. The high-efficient water-purifying activated carbon is prepared from the following raw materials in parts by weight: 60 to 80 parts of activated carbon, 20 to 40 parts of modified diatomite, 15 to 25 parts of zeolite, 10 to 30 parts of kaolin, 5 to 10 parts of alum powder, 3 to 8 parts of montmorillonite, 5 to 15 parts of sepiolite powder, 3 to 6 parts of calcium carbonate powder, 4 to 10 parts of binding agent and 30 to 50 parts of deionized water. The preparation method of the high-efficient water-purifying activated carbon comprises the following steps: (1) a pre-treatment process; (2) a carbonization process; (3) an activation process. The high-efficient water-purifying activated carbon disclosed by the invention has the advantages of high mechanical strength, good adsorption capability, good water purification effect and the like; therefore, the activated carbon is desired water-purifying activated carbon, and is suitable for being massively promoted and used.

Description

technical field [0001] The invention relates to the technical field of water purifying agents, in particular to a high-efficiency water purifying activated carbon and a preparation method thereof. Background technique [0002] With the development of industry, the degree of pollution of urban drinking water sources is increasing. At the same time, with the improvement of living standards, people's requirements for drinking water quality and drinking water quality standards are becoming more and more stringent. [0003] Due to its huge specific surface area and developed pore structure, activated carbon has a strong adsorption capacity for dissolved organic matter in water such as phenolic compounds, and is suitable for drinking water purification. At present, there are two main types of activated carbon products used in the market, that is, made of columnar activated carbon, or directly crushed by raw coal. These two types of products have disadvantages that are difficult to...
