Device for deeply treating chemical wastewater through electrocatalytic oxidation

The utility model discloses a device for deeply treating chemical wastewater by electrocatalytic oxidation, and relates to the technical field of chemical wastewater treatment devices, an interlayer is arranged between an inner kettle body and an outer kettle body of a sewage treatment kettle, a conveying type foam scraper is arranged at the upper end of the inner kettle body, and a scraper chain is arranged between a main chain wheel and a driven chain wheel. The scraper chain is respectively meshed with the driving chain wheel and the driven chain wheel, and a floating foam collecting opening is formed in the bottom of the outer kettle body and is communicated with the interlayer. The driving shaft rotates along with the driving motor to drive the scraper chain to continuously turn over between the main chain wheel and the driven chain wheel, so that floating foam generated in the inner kettle body is continuously scraped into the interlayer and finally discharged through the floating foam collecting port,
