Abstract

The invention provides a porous ore filter element material and a preparation method thereof, and the porous ore filter element material is prepared from the following raw materials: a main material, an adhesive and a pore forming agent, the main materials are selected from the following raw materials: medical stone, limonite, selenium ore, celestite, shell, silicate ore and magnesium ore; the adhesive is selected from the following components: sodium silicate, clay, shellac, rosin, dextrin and synthetic resin; the pore-forming agent is selected from the following components: ammonium bicarbonate, sodium bicarbonate, sodium carbonate and calcium carbonate. The filter element material disclosed by the invention is used for optimizing drinking water mineralization treatment, so that selenium and strontium elements in effluent quality can simultaneously reach the level of natural mineral water; the material is formed by secondary modification processing of natural ore with high mineral dissolution, the specific surface area of the material is increased through modification, and the dissolution performance of the natural ore is improved.

Description

technical field [0001] The invention relates to the technical field of water treatment materials, in particular to a porous ore filter element material and a preparation method thereof. Background technique [0002] Water is the source of life, and the safety and health of drinking water is related to the survival and development of the entire human being. With the progress of the times and the continuous improvement of the quality of life, the people's demand for high-quality drinking water is also becoming more and more intense. [0003] Drinking water is an important way to supplement the elements needed by the human body in addition to food, and the quality of water will also directly affect people's health. Long-term drinking of purified water without mineral elements will have a negative impact on human health, making the human body lack of essential macro and trace elements. Studies have shown that drinking purified water for a long time can cause health risks such ...
