Description

Purple sand filtration water purification material with multifunctional health care function and manufacturing method thereof

Technical Field

The invention relates to the technical field of water purification, in particular to a multifunctional health-care purple sand water filtering and purifying material and a manufacturing method thereof.

Background

At present, most of tap water plants in China still adopt conventional treatment, and due to the quality of urban pipe networks, the water discharged from the tail ends of the pipe networks cannot meet the requirements of different people on drinking water. Therefore, the purchase of barreled water and various bottled water, and the installation of a household water purifier at the end of a pipe network have become the choice of most residents at this time.

The water purification function of water purifier mainly realizes through the filter core, and at present, the water purifier filter core of prior art generally is high-quality fibre and active carbon, and the quality of water after the filtration purification treatment has often become low mineralization degree water, is called soft water again, and is similar with bottled water or bottled water of selling on the existing market, and its characterized in that mainly has following two points: (1) the pH value of the low mineralized water is generally between 6.0 and 6.8, and the low mineralized water is weakly acidic; (2) the contents of macroelements and trace element ions required by human bodies in the low mineralized water are generally low, and some mineral substances (such as purified water and distilled water) are even not contained. And the long-term drinking of the low-hardness water is very unfavorable for the health of human bodies, so that the improvement of the content of calcium and magnesium ions in the drinking water in a certain range is beneficial to the human bodies. In addition, many studies have shown that drinking water with low mineralization, such as low salt content, for a long time has certain influence on cardiovascular and cerebrovascular systems, urinary systems and reproductive systems of human bodies; other researches show that the low mineralized drinking water has certain correlation with esophageal cancer, colon cancer, gastric cancer and the like.

For this reason, natural mineral water, which is expensive, is also present in the market. As long as one of the contents of strontium, selenium and zinc meets the requirement, the mineral water can be regarded as high-quality mineral water according to the standard of GB8537-2008 natural mineral spring for drinking, wherein the standard specifies that the content of strontium is more than or equal to 0.20mg/L, the content of zinc is more than or equal to 0.20mg/L and the content of selenium is within the range of 0.01-0.05 mg/L.
