Abstract

The invention discloses an active carbon filter core for water purification, which is prepared from, by weight, 120-200 parts of active carbon, 1-3 parts of polyethylene, 10-15 parts of sodium selenite, 8-10 parts of clay, 10-12 parts of magnesium, 5-10 parts of medical stone, 5-10 parts of a deodorant, 20-30 parts of attapulgite, 5-8 parts of nano-titanium oxide, and 2-6 parts of tourmaline powder. The active carbon filter core has good adsorption effect and good water purification effect. A preparation method includes: 1, weighing the raw materials according to the formula; 2, mixing the rawmaterials, and milling and pulverizing the raw materials; 3, placing the mixture in a mold and applying pressure, and performing sintering thermal treatment on the press-shaped materials in a furnace, wherein the temperature is maintained at 300-320 DEG C for 50-80 min in the furnace, then after the product is sintered and shaped, cooling the product to 20-30 DEG C, and demolding the product to obtain the active carbon filter core.

Description

technical field [0001] The invention belongs to the technical field of water purification, specifically relates to an activated carbon filter element for water purification, and also relates to a preparation method of the aforementioned activated carbon filter element for water purification. Background technique [0002] The pollution of urban pipelines and the pollution of major lakes has accelerated the development of water purifiers. The core of water purifiers, when heat is its "core". [0003] As far as the current water pollution environment is concerned, the selection and use of activated carbon is the core technical issue for water treatment and purification; the traditional activated carbon rod filter element has limited purification effect on the pollutants contained in drinking water, and its activity is not good for drinking water sourced from reservoirs. Not strong, the production process lags behind. Contents of the invention [0004] The purpose of the pres...
