Abstract

The application discloses a solar photo-thermal foam for treating salt-containing organic wastewater and a preparation method thereof. The application solves the problems of poor desalination effect, low degradation ability for organic pollutants, especially volatile organic pollutants, and easy concentration of organic pollutants in the bottom liquid in the process of treating salt-containing organic wastewater by solar photo-thermal treatment. The application comprises the following steps: preparing a photo-thermal foam by loading a copper-cobalt binary metal catalyst on a nickel-based metal foam, and using the photo-thermal foam to treat water in a device for treating salt-containing organic wastewater by solar photo-thermal treatment. The porous foam substrate is used to construct a high-performance photo-thermal foam with a special morphology, and under the synergistic action of a multi-metal catalytic system, efficient desalination and catalytic persulfate degradation of organic pollutants in the bottom liquid and condensate are realized in the process of treating salt-containing organic wastewater by solar photo-thermal treatment, so that high-quality pure water is obtained. In addition, the photo-thermal foam catalyst is simple to recover and can effectively inhibit metal leaching toxicity, and has good repeated stability.
