The organic pollutants often have an ultra-long half-life period in a natural water body, have great harm to aquatic environment organisms, and have the possibility of entering a drinking water source, thereby threatening the health of human bodies.
Ozone has been widely used in the field of water treatment as a conventional oxidizing agent, and the technology of combining ozone with hydrogen peroxide can significantly improve the water treatment effect compared with the technology of using ozone alone for water treatment. HO produced by decomposition of hydrogen peroxide2 -Can initiate chain reaction to greatly improve the steady-state concentration of HO & generated in a reaction system, and has the advantages of degrading pollutants in water by utilizing the synergistic action of ozone and HO & and oxidizing and decomposing organic pollutants difficult to be biodegraded into micromolecular organic matters to reduce the pressure of subsequent biological treatment or completely oxidizing and decomposing the organic pollutants into CO2And H2Inorganic molecules such as O and the like greatly reduce COD of polluted water and reduce the toxicity of the waterAnd the harm of toxic and harmful substances to water environment and organisms is weakened.
