BDD electrodes are indeed advanced in electrocatalytic processes. They provide excellent performance due to their wide electrochemical window and stability, allowing efficient direct or indirect oxidation of organic pollutants. This technology is particularly effective in treating wastewater with minimal secondary pollution and is adaptable for integration with other treatment methods.
Technical advantages
1. The reagent is a clean reactant-electrons.
2. Operates under ambient temperature and pressure, making management simple.
3. The treatment device has a small footprint.
4. Water quality stability can be ensured by adjusting the voltage and current.
5. Uses low-voltage direct current for degradation, avoiding the need for large amounts of chemical reagents.
6. Under the same conditions, BDD electrodes offer significantly better efficiency and energy consumption for organic degradation compared to other electrodes.
BDD electrodes are effective in degrading pollutants in various types of organic wastewater, including:
1. Phenolic compounds and their derivatives, such as phenol, mainly from petrochemical industries.
2. Pharmaceutical intermediates, such as 17β-estradiol, primarily from pharmaceutical chemical industries.
3. Dyes and pigments, such as methyl orange, mainly from dyeing and printing plants.
4. Herbicides and pesticides, such as chlorsulfuron, primarily from pesticide production companies.
5. Surfactants, such as those in car wash wastewater.
