The application belongs to the technical field of metal recovery, and provides a gold electrolytic recovery method and device based on AI vision, which can transfer the pretreated gold ion-containing electrolytic mother liquor to an electrolytic cell provided with a deposition plate, deposit gold on the deposition area on the surface of the deposition plate, continuously collect images of the deposition area by a camera unit, calculate the dense gold layer coverage rate and deposition defect area ratio of the deposition area by using a detection model, realize dynamic adjustment of the electrolysis parameters, and stop electrolysis and complete the current deposition when the preset completion condition is met. The scheme realizes non-contact real-time quantitative detection of the state of the gold deposition layer during the electrolysis process, can dynamically adjust the electrolysis parameters based on the model detection coverage rate, and preferentially triggers the inhibition operation when the defect area exceeds the standard, ensures that the deposition process is carried out in an excellent state, improves the consistency of the deposition product, reduces the requirements for the experience and concentration of the operator, and reduces human errors.

The application discloses a catalytic degradation device for organic pollutants and belongs to the field of organic pollutant treatment. The device comprises a treatment tank and a tank cover installed on the upper portion of the treatment tank. A plurality of partition plates are linearly connected in the tank cover. When the tank cover moves downward, the partition plates contact the bottom wall of the treatment tank, thereby dividing the treatment tank into a plurality of spaces. When the tank cover moves downward, the partition plates contact the bottom wall of the treatment tank, thereby dividing the treatment tank into a plurality of independent reaction chambers. Each reaction chamber can independently perform a catalytic degradation reaction, thereby improving the reaction efficiency and degradation effect. Meanwhile, the linearly connected partition plates can ensure the material transmission and mixing between the reaction chambers, thereby realizing more uniform reaction conditions. When the treatment tank is filled with organic pollutant wastewater to be treated, the tank cover is in an upward moving state. At this time, the partition plates do not contact the bottom wall of the treatment tank, thereby reducing the resistance of the organic pollutant wastewater filling.
