Integrated electrochemical oxidation principle

Description:
Electrochemical oxidation technology is an important Advanced Oxidation technology in the field of Water Treatment. Its core is to use the strong oxidizing substances generated by electron transfer or electrode reaction on the electrode surface (such as hydroxyl radicals · OH, ozone O3, hypochlorous acid HClO, etc.) to oxidize and decompose pollutants in water (especially difficult to biodegrade organic compounds, heavy metal ions, etc.) into harmless substances (such as CO ₂, H ₂ O) or convert them into easily treatable forms. This technology has been widely studied and applied in industrial wastewater, leachate, and drinking water purification due to its mild reaction conditions, strong controllability, and minimal secondary pollution.

Advantage:

Efficiency: It can directly oxidize or decompose difficult to degrade pollutants (such as polycyclic aromatic hydrocarbons and heterocyclic compounds) through highly active species, with a much higher removal rate than traditional biochemical methods.
Environmentally friendly: No need to add chemical oxidants (or only a small amount of auxiliary electrolytes such as NaCl), avoiding secondary pollution; The products are mostly harmless substances such as CO ₂ and H ₂ O.
Easy to control: By adjusting parameters such as current, voltage, and reaction time, the processing effect can be flexibly controlled, making it suitable for automated operation.
Wide adaptability: It has good tolerance to high salt, high acid/alkali, and highly toxic wastewater, and is not limited by pollutant concentration (can be treated from μ g/L to g/L).
