Description

technical field [0001] The invention belongs to the technical field of electrocatalytic oxidation treatment of refractory organic wastewater, and in particular relates to a modified foam titanium particle electrode with the function of electrocatalytically removing chlorophenol and a preparation method thereof. Background technique [0002] Electrocatalytic oxidation technology is a very promising water treatment technology that has gradually developed in recent years. It mainly oxidizes and degrades organic pollutants in wastewater by generating hydroxyl radicals and other active groups with strong oxidizing properties. Refractory organic matter or biotoxic pollutants are converted into biodegradable or non-toxic substances, improving the biodegradability of wastewater, thereby facilitating subsequent biological treatment. Therefore, the electrocatalytic oxidation water treatment technology has the characteristics of no secondary pollution, low cost, strong applicability, a...

Problems solved by technology

However, the high resistance and low conductivity of traditional electrode materials lead to low current efficiency, insufficient stability, short life, and high cost of electrode materials in wastewater treatment, which limits the application and development of electrocatalytic oxidation technology in water treatment. , so the research and preparation of new electrode materials need to be further strengthened

At present, there is still a lack of electrode materials and preparation methods with high-efficiency electrocatalytic removal of p-chlorophenol specific pollutants
