Mineral filtering material and preparation method thereof, and filtering core obtained from mineral filtering material

Abstract

The invention discloses a mineral filtering material and a preparation method thereof, and a filtering core obtained from the mineral filtering material, wherein the mineral filtering material comprises the following raw materials by weight: 9-24 parts of secondary quartzite, 3-8 parts of feldspar quartz sandstone, 2-5 parts of rhodochrosite, 20-40 parts of zeolite, 10-30 parts of active carbon particles, 5-20 parts of active carbon fibers and 20-40 parts of a binder, wherein the rhodochrosite is a mixture of iron rhodochrosite and zinc rhodochrosite according to a weight ratio of 1-3:2, and the zeolite is a mixture of phillipsite and analcime according to a weight ratio of 1-3:1. The invention further provides a preparation method of the filtering material and a filtering core prepared from the filtering material. According to the invention, the filtering core capable of stably releasing mineral substances beneficial to growth and development of infants is obtained by utilizing natural rock materials through reasonable matching, and is environmentally friendly, free of secondary pollution and free of heavy metal exceeding the standard, wherein the TDS of the water mineralized by the filtering core is kept at 10-40 mg / L.

Description

technical field

[0001] The invention belongs to the technical field of water treatment, in particular to a mineral filter material, a preparation method thereof and a obtained filter element. Background technique

[0002] Water is the source of life, and children are the source of hope. The physiological functions of infants and young children are not yet mature, so most parents will pay special attention to their diet and drinking water health. Due to the severe water pollution situation, the drinking water safety of infants and young children is seriously threatened. On the one hand, various heavy metals, antibiotics and other pollutants in water seriously threaten the health of infants and young children. Under the same concentration of pollutants, infants are more vulnerable to harm; on the other hand, due to the immature liver and kidney functions of infants and young children Maturity, drinking water with high TDS for infants and young children will increase the burde...
