Embodiment 1

[0127] The mineralized filter core 20 of the filter 100 of the present embodiment is made by the following method:

[0128] Preparation of modified ginger stone

[0129] Take 10kg of natural ginger stone and ultrasonically treat it with deionized water to obtain ginger stone powder with a particle size of 35-100 mesh, and then calcinate it at 900°C for 2 hours, then add it to a mixture containing 0.08kg citric acid and 2L deionized water according to the solid-liquid ratio of 5:1. In the solution of ionized water, take out after cooling, then filter and dry after washing with deionized water, obtain modified ginger stone;

[0130] Preparation of modified calamine

[0131] 1 kg of natural calamine was ultrasonically treated with deionized water to obtain calamine powder with a particle size of 35-100 mesh, and then calcined in an argon atmosphere at 750 ° C for 1 h, and then quickly put into 5 L of 0.1 mol / L dilute In hydrochloric acid, after cooling, add 5L of NaOH solution ...

Embodiment 2

[0139] This embodiment is basically the same as that of Embodiment 1, except that 20 g of modified ginger stone and 5 g of modified calamine are used to prepare the mineralized filter element 20 of the filter 100 of this embodiment.

Abstract

The invention discloses a mineralized filter element based on a rock and polymer composite material. The mineralized filter element comprises a polymer, modified ginger stone and modified calamine. The surface of the modified ginger stone is loose and porous, the total pore volume is large, and the specific surface area is large, so that when the mineralized filter element is used for filtering water, the contact area of the modified ginger stone and the water is large, calcium ions in drinking water can be increased, heavy metal elements such as cadmium, chromium, lead and copper in the water can be effectively adsorbed, and the water quality is improved. The antibacterial effect is relatively strong. Besides, the surface of the modified calamine is loose and porous, so that when the mineralized filter element is used for filtering water, the contact area of the modified calamine and the water is large, a large amount of elements such as zinc required by a human body can be released into the water, and the mineralized filter element has a strong antibacterial effect. In addition, the invention further discloses a preparation method of the mineralized filter element and a filter applying the mineralized filter element.

Description

technical field [0001] The present application relates to the technical field of drinking water mineralization, and in particular to a mineralization filter element based on rock and polymer composite materials, a preparation method of the mineralization filter element, and a filter using the mineralization filter element. Background technique [0002] Water is the source of human life and an important substance to sustain life. At present, water pollution on the earth is becoming more and more serious. However, with the development of social economy, people pay more and more attention to safe and healthy drinking water, and most people will obtain safe and healthy drinking water through household water purifiers. [0003] At present, the water purifiers on the market can carry out advanced treatment of water to remove pollutants such as heavy metals, antibiotics, and microplastics in the water. However, while the existing water purifiers are carrying out advanced treatment...
