[0021] (III) Beneficial Effects

[0022] This application provides a device for treating chemical wastewater. It has the following beneficial effects:

[0023] 1. This chemical wastewater treatment device, through the coordinated arrangement of various components in the photocatalytic oxidation mechanism, uses an electric slide rail to drive the sliding block to move, which in turn causes the ultraviolet lamps on the mounting frame to move flexibly on the surface of the treatment tank, effectively expanding the light coverage area. Compared with traditional fixed devices, this design allows pollutants in the wastewater to fully receive ultraviolet irradiation. Under the action of the photocatalyst, the oxidation and decomposition efficiency of pollutants such as organic matter is significantly improved, pollutant residues are reduced, and more comprehensive and efficient treatment of chemical wastewater is achieved, ensuring that the treated water quality meets the standards.

[0024] 2. The chemical wastewater treatment device, through the coordinated arrangement of the catalyst mechanism and the stirring mechanism, ensures that the catalyst in the catalyst placement tank is evenly sprayed into the pretreatment tank via the second delivery pump, catalyst pipeline, and delivery spray plate. The motor drives the stirring frame to quickly and thoroughly mix the catalyst with the wastewater. This not only accelerates the chemical reaction process and improves the pretreatment efficiency, but also ensures full contact between the catalyst and pollutants, enhancing the treatment effect. At the same time, uniform stirring avoids the precipitation of impurities, provides stable water quality conditions for subsequent treatment, reduces the load on subsequent units, and improves the overall treatment efficiency and stability of the device.
