Application and research progress of hydrogen peroxide in water treatment
Peroxides are widely used in the field of water treatment,and have good removal effects on heavy metal ions,harmful bacteria and difficult to degrade organic matter in water bodies.Their research and development and popularization have become highly concerned topics in the field of environmental protection.The mechanism and application research progress of different activation modes of hydrogen peroxide in advanced oxidation in the water treatment process were reviewed.The research and application progress of catalyst activation,external energy activation,activation of hydrogen peroxide in combination with other peroxides,photocatalytic and electrocatalytic in situ generation of hydrogen peroxide in water treatment were discussed from the two aspects of activation and reduction of hydrogen peroxide consumption.In view of the great research potential of new activation modes of peroxides,it was expected to expand and accelerate the application and research of new peroxides in the field of water treatment and to reduce the influence of peroxides on catalysts and stability in the system.
