Problems solved by technology

However, membrane materials such as ultrafiltration membranes, microfiltration membranes, nanofiltration membranes, and reverse osmosis membranes only function to intercept harmful substances such as bacteria, colloids, and organic matter, and the intercepted bacteria cannot be effectively killed; after activated carbon absorbs organic matter, it is easy to Allows bacteria to grow on its surface; ion exchange resins are not inherently capable of handling bacteria
None of the water treatment materials can effectively kill bacteria or inhibit the growth of bacteria, which will easily lead to secondary pollution of the water purifier and affect water quality.

Abstract

The invention discloses a slow-release antibacterial adsorption material for drinking water treatment. The material is prepared from, by weight, 10%-60% of hydrophobic organic macromolecule polymer, 20%-50% of hydrophilic organic macromolecule polymer, 2%-20% of inorganic porous adsorbent, 0.5%-20% of antibacterial agent, 2%-5% of baking soda and 2%-10% of pore-forming agent. The invention further discloses a preparation method of the slow-release antibacterial adsorption material for drinking water treatment. According to the slow-release antibacterial adsorption material for drinking water treatment and the preparation method of the material, bacteria can be inhibited and killed effectively for a long time, secondary contamination to a water purifying machine due to microorganism breeding is eradicated, and the service life of a filter material is prolonged.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a slow-release antibacterial adsorption material for drinking water treatment and a preparation method thereof. Background technique [0002] In the prior art, the water treatment materials of household water purifiers mainly include materials such as ultrafiltration membranes, microfiltration membranes, nanofiltration membranes, reverse osmosis membranes, activated carbon, and ion exchange resins. However, membrane materials such as ultrafiltration membranes, microfiltration membranes, nanofiltration membranes, and reverse osmosis membranes only function to intercept harmful substances such as bacteria, colloids, and organic matter, and the intercepted bacteria cannot be effectively killed; after activated carbon absorbs organic matter, it is easy to Allows bacteria to grow on its surface; the ion exchange resin itself does not have the ability to deal with bacteria. No...
