Abstract: In the actual water treatment process, high energy consumption has always been the main limiting factor restricting the application of electrocatalytic oxidation technology in water treatment engineering. In order to reduce the energy consumption of electrocatalytic oxidation technology in treating organic pollutants in water, zirconium nitride intermediate layer was introduced by arc spraying technology, and the stability and service life of titanium-based PbO2 anode were improved by electrodeposition. The results show that by adding zirconium nitride intermediate layer, the crystal particles of PbO2 are significantly refined, the particle distribution is more uniform, and the crystal structure is more dense. This structural optimization significantly improves the resistance of the electrode surface to electrolyte erosion, thus enhancing the stability and durability of the electrode. The results of the treatment of wastewater containing 4-amino-7 chloroqualine showed that the removal rate of pollutants could reach 95.85% after electrolytic treatment with current density of 20mA/cm2 for 3 hours under neutral conditions. This research can effectively treat organic pollutants in water treatment engineering, and provide effective solutions for water bodies containing complex pollutants such as chemical wastewater.
