Abstract

The invention discloses a preparation method high-efficiency water purifying activated carbon, wherein the activated carbon is prepared from the following components by weight percent: 50-70% of petroleum coke, 10-40% of raw coal, 5-20% of a binding agent and 0.5-10% of an activating agent. Specific preparation steps are as follows: (1) respectively weighing petroleum coke and raw coal according to proportion, crushing and uniformly mixing; (2) adding the binding agent according to proportion for briquetting forming to form a briquetting block; (3) performing carbonization treatment in a carbonization furnace; (4) smashing the carbonization material, and uniformly mixing with the activating agent; (5) performing activating treatment; and (6) washing and drying to obtain the high-efficiencywater purifying activated carbon. The preparation method provided by the invention is simple in technological process, and low in operation cost, and the prepared activated carbon product has the advantages of being high in mechanical strength and good in adsorption property, and has a relatively good water quality purifying effect.

Description

technical field [0001] The invention relates to the technical field of activated carbon, in particular to a preparation method of highly efficient water-purifying activated carbon. Background technique [0002] 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 solve when used for water purification, and it is difficult to achieve the purpose of purifying water. [0003] In view of the above problems, a coal-based activated carbon and its manufacturing method are proposed in Chinese patent CN1194235. The activated carbon does not go through the pulverizing and molding...
