Background
The organic wastewater in the laboratory is wastewater with wide pollution range and great harm. The organic wastewater comprises the following components in part by weight: carbon tetrachloride, chloroform and the like can be recycled by drying or distillation treatment. The part which is not recyclable or difficult to recycle needs to be treated and then can be discharged. The advanced oxidation water treatment stage is a method for effectively treating organic wastewater developed in recent years. Which converts organic pollutants into carbon dioxide, water, etc. through an oxidation process. The light-assisted catalytic oxidation method is one of the commonly used methods for improving the removal efficiency of organic pollutants by catalytic oxidation. The method drives the removal of organic pollutants by introducing external ultraviolet light and a photoresponse catalyst. However, the method is usually carried out at room temperature, which is not favorable for the catalytic oxidation of organic pollutants. If an additional heating device is introduced, the equipment is complicated, and the energy utilization efficiency is not high. In addition, the conventional ultraviolet light-assisted catalytic oxidation treatment method does not effectively utilize the 'photothermal effect' in the ultraviolet light irradiation process.
