Electrocatalytic oxidation is a highly efficient sewage treatment process. It uses electric fields to drive pollutants to undergo redox reactions on the electrode surface. It has the characteristics of high-efficiency oxidation, strong selectivity, simple and flexible operation, and environmental friendliness. It can deeply oxidize organic matter that is difficult to biodegrade, and does not require the addition of chemical agents, and there is no secondary pollution.
Electrocatalytic oxidation is an advanced oxidation process based on electrolysis reaction. It uses an external electric field to drive pollutants in wastewater to undergo redox reactions on the electrode surface. At the anode, pollutants directly or indirectly receive electrons and are oxidized into small molecules or harmless substances that are easily biodegradable; at the cathode, water receives electrons to generate hydrogen and hydroxide ions, which enhances the alkaline environment of the system and helps promote the decomposition of pollutants.
Application characteristics of electrocatalytic oxidation in sewage treatment
High-efficiency oxidation ability: Electrocatalytic oxidation can effectively activate and activate oxidants such as oxygen or persulfate in wastewater to form highly oxidizing hydroxyl radicals, thereby deeply oxidizing various organic matter that is difficult to biodegrade.
Strong selectivity: By designing catalysts with specific active sites, such as coated electrodes doped with metal oxides, the oxidation efficiency of target pollutants can be specifically improved.
Easy and flexible operation: This technology can adjust parameters such as current density, voltage and electrolysis time according to changes in wastewater composition and concentration to meet different treatment needs.
Environmentally friendly: No chemical agents are added during the entire treatment process, there is no secondary pollution, and while generating hydroxyl free radicals with strong oxidizing ability, it can also stabilize some heavy metal ions.
