When the box cover 701 is closed, the box cover 701 presses the movable block 708 to displace through the guide block 706; when a certain position is moved, the guide block 706 is in contact with the press switch 705, so that the press switch 705 is pressed down, the catalytic lamp 703 mounted on the box cover 701 is turned on, and then the catalytic lamp 703 performs photocatalytic degradation on the internal liquid medicine and copper slag pollutants. The case 1 is integrally sealed through the sealing layer 702, so that the catalysis effect is ensured, and the photocatalytic degradation efficiency is higher.
In this embodiment, the photocatalytic degradation device provided by the present invention is compared with the existing photocatalytic degradation device for degradation treatment of copper slag pollutants, and the comparison results are shown in the following tables:
table one: a table of the catalytic times required to catalyze pollutants using existing photocatalytic devices:
| pollutant/kg | 100 | 200 | 300 | 400 | 500 | 600 | 700 |
| Time/h | 5.5 | 12.1 | 18.3 | 24.4 | 30.8 | 36.6 | 42.2 |
Table two: a table of the catalysis times required for the catalysis of pollutants by means of the photocatalytic device of the invention:
through the comparison of the data, the working efficiency can be reduced along with the increase of time, and the existing photocatalytic device has longer catalytic time under the same condition and lower catalytic efficiency. The photocatalytic degradation device provided by the invention has a better photocatalytic degradation effect, and can realize better catalysis under the same conditions.
Finally, it should be noted that: the above-mentioned embodiments are only specific embodiments of the present invention, which are used for illustrating the technical solutions of the present invention and not for limiting the same, and the protection scope of the present invention is not limited thereto, although the present invention is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: any person skilled in the art can modify or easily conceive the technical solutions described in the foregoing embodiments or equivalent substitutes for some technical features within the technical scope of the present disclosure; such modifications, changes or substitutions do not depart from the spirit and scope of the embodiments of the present invention, and they should be construed as being included therein.
