Abstract

The invention relates to a composite antibacterial flowing water filter element. The filter element comprises the following raw materials in parts by weight: 300-500 parts of diatomite raw ore, 100-200 parts of potash feldspar, 100-200 parts of kaolin, 40-50 parts of multielement ion antibacterial agent, 40-50 parts of multielement hydrate reduction antibacterial agent and 50 parts of carbonized activated carbon. The hydrate reduction antibacterial agent, multielement ion antibacterial agent and husk activated carbon have great antibacterial effects on anaerobic bacteria and aerobic bacteria in water; the carbonized husk activated carbon has higher activity and adsorptive power than other common activated carbon; besides, metal ions carried inside the activated carbon have great adsorptive power and antibacterial performance for metals in water; in addition, under the disinfection action of the antibacterial agent, various bacteria and metal ions can be adsorbed and intercepted; the raw materials are simple and are not wasted; and the problem of bacteria saturated adsorption in the common filter element is greatly improved.

Description

technical field [0001] The invention relates to the field of antibacterial materials, in particular to a composite antibacterial running water filter element and its preparation process Background technique [0002] Inorganic antibacterial agents have become a class of antibacterial agents with potential and people's willingness to choose because of their outstanding characteristics such as broad-spectrum antibacterial, persistence, chemical stability, heat resistance, safety, and bacteria are not easy to develop drug resistance. Inorganic antibacterial agents are composed of antibacterial active ingredients and carriers. The antibacterial active ingredients are mainly metal ions. Currently, the most widely used antibacterial metal ions are silver, zinc, copper, etc. Comparing the antibacterial properties of silver, copper, and zinc ions, silver ions have the strongest antibacterial ability, but are expensive, which limits their application to a certain extent; although the ...
