Abstract

The invention discloses composite function resin, and belongs to the field of resin. The composite functional resin has a basic structure shown as a formula (I) and / or a formula (II), wherein the AX is a quaternary ammonium group. By aiming at the problems that the existing resin has poor anti-interference capability during sterilization, and the capability of removing soluble organic matters in the water and sterilizing byproduct precursors and poor ability of negative ions such as nitrate radical, sulfate radical, phosphate radical and arsenate radical, the invention provides the composite function resin. The composite function resin simultaneously has the capability of effectively eliminating soluble organic matter in the water and sterilizing the byproduct precursors and negative ionssuch as nitrate radical, sulfate radical, phosphate radical and arsenate radical, and has the advantages of efficient sterilization capability and anti-interference capability. The invention providesa preparation method of the composite function resin, application of the composite function resin to sterilization, and application of the composite function resin to water treatment. The formulas areshown in the description.

Description

technical field [0001] The invention belongs to the field of resins, and in particular relates to a composite functional resin as well as its preparation method and application. Background technique [0002] The disinfection process is the most important way to kill pathogenic microorganisms and ensure the safety of drinking water, mainly including chemical methods such as chlorine gas, chloramine, sodium hypochlorite, chlorine dioxide, ozone, compound disinfection, and physical methods such as ultraviolet radiation. However, during the disinfection process, chemical disinfectants will react with natural organic matter, artificially synthesized organic pollutants, bromide, iodide, etc. in water to generate a variety of disinfection by-products, such as trihalomethanes, haloacetic acids, haloacetonitriles, and nitrosamines. Wait. Many disinfection by-products are genotoxic and carcinogenic, which seriously threaten the safety of drinking water. UV disinfection can also caus...
