Problems solved by technology

[0003] Antibacterial agents used in water treatment can be divided into organic antibacterial agents, inorganic antibacterial agents and natural antibacterial agents. Known inorganic antibacterial agents include apatite, zeolite, glass, zirconium phosphate, silica gel, etc. loaded with silver or copper, etc. Antibacterial metal substances, but inorganic antibacterial agents are generally powder antibacterial agents, which are prone to water turbidity and are not easy to recycle

Abstract

The invention discloses an antibacterial water treatment material and a preparing method thereof.The antibacterial water treatment material is prepared from, by weight, 50-58 parts of polyvinyl butyral, 6-9 parts of chitosan fibers, 5-7 parts of diisobutyl phthalate, 2-3 parts of phenoxyethanol, 1-2 parts of 1,8-diazabicyclo(5,4,0)7-hendecene, 0.8-1 part of peroxide terephthaloyl, 0.5-1 part of 5,6,7,3',4'-pentamethoxyl flavone, 0.5-0.8 part of zinc borate, 0.2-0.5 part of ammonium oxalate, 0.2-0.3 part of aluminum sulfate and 0.8-0.5 part of perillaldehyde.The invention further provides the preparing method of the antibacterial water treatment material.

Description

technical field [0001] The invention belongs to the field of water treatment materials, in particular to an antibacterial water treatment material and a preparation method thereof. Background technique [0002] The way humans have treated water has been around for quite a long time, including physical and chemical methods. Physical methods include the use of various filter materials with different pore sizes, and the use of adsorption or barrier methods to exclude impurities in the water, so that larger impurities cannot pass through, and then obtain cleaner water. Physical methods include precipitation method, which refers to allowing impurities with a small specific gravity to float on the water surface to remove them, or to allow impurities with a large specific gravity to settle down to filter them out. The chemical method is to use various chemicals to convert the impurities in water into substances that are less harmful to the human body, or to concentrate the impurit...
