The two sides of the catalytic plate 3046 are sprayed with catalyst. The screw between the clamping groove 3044 and the catalytic plate 3046 can be removed to replace the catalytic plate 3046. The catalytic plate 3046 is a porous plate.

[0028] When in use, sewage is poured into the reaction box 1 from the water inlet pipe 104. When the reaction box 1 is filled with sewage, the light source system 2 and the catalytic stirring assembly 3 work at the same time. In this process, the light emitted by the catalytic light source 203 irradiates the roller assembly 304 from both sides. The roller assembly 304 rotates by the driving of the motor 305. Since the roller assembly 304 rotates continuously, all the catalytic plates 3046 are alternately close to the catalytic light source 203, thereby improving the utilization rate of the catalyst. Since the roller assembly 304 rotates continuously and the diameter of the roller assembly 304 is basically the same as the width of the reaction box 1, the rotating roller assembly 304 can make the sewage in the reaction box 1 continuously roll. Since the catalytic plate 3046 sprayed with catalyst rotates continuously and the sewage rolls continuously, the sewage can quickly and uniformly contact with the catalyst, thereby improving the efficiency of catalysis. In this process, since the glass window 103 is very close to the continuously rotating roller assembly 304, it is very convenient to observe the use of all catalysts through the glass window 103 to understand the reaction of the sewage. When the catalyst needs to be replaced, the catalytic stirring assembly 3 is lifted up by a crane or manually after the screw is removed. Then, the roller assembly 304 is taken out by removing the nut under the rotating shaft 303. Further, a new roller assembly 304 is inserted and locked by the nut to complete the replacement of the catalyst. In this process, since the device is equipped with multiple catalytic stirring assemblies 3, the removed assembly can still purify sewage. Since the opening for installing the catalytic stirring assembly 3 is upward and the disassembly does not interfere with other structures, the replacement can be completed smoothly without stopping the machine, which is very convenient. For the roller assembly 304 with ineffective catalyst, only the new catalytic plate 3046 needs to be replaced to put it into use again, so that the replacement of the catalyst only needs to discard the catalytic plate 3046 sprayed with catalyst, thereby saving the replacement cost of the catalyst.

[0029] In summary, the photocatalytic oxidation water treatment device has the following advantages: the catalytic stirring assembly 3 is installed between the two light source systems 2 and is very close to the two light source systems 2, and the catalytic plate 3046 sprayed with the catalyst continuously rotates under the driving of the motor 305, so that all the catalysts can uniformly receive the light source, thereby improving the utilization rate of the catalyst; when the motor 305 drives the roller assembly 304 to rotate, not only does the catalyst continuously rotate and change position, but also the catalytic plate 3046 stirs the sewage to continuously roll, so that the sewage can uniformly contact the catalyst to improve the reaction efficiency; since the glass window 103 corresponds to the position of the catalytic stirring assembly 3 and the glass window 103 is close to the continuously rotating roller assembly 304, the conditions of all the catalytic plates 3046 can be observed at close range through the glass window 103, thereby achieving the effect of facilitating observation of the reaction conditions; since the catalytic stirring assembly 3 is inserted from the top of the reaction box 1, the catalyst can be replaced very conveniently by simply pulling out the catalytic stirring assembly 3; since the catalytic stirring assembly 3 is large in number and the installation port is upward, the device can still operate normally when one catalytic stirring assembly 3 is removed to replace the catalyst; when the catalyst is replaced, the nut fixing the roller assembly 304 can be unscrewed to replace a new catalytic stirring assembly 3, which is very convenient; at the same time, the roller assembly 304 with the catalyst that has lost its effectiveness does not need to be directly discarded, but can continue to be used by replacing a new catalytic plate 3046, thereby reducing the production cost.

[0030] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacements or changes to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered by the protection scope of the present application.
