[0003] Wastewater treatment is a crucial aspect of environmental protection and sustainable resource utilization, involving various technologies and methods aimed at removing pollutants from wastewater to meet discharge standards or enable reuse. Wastewater treatment is a complex systems engineering project, requiring the selection of appropriate treatment technologies and processes based on the wastewater's characteristics, treatment objectives, and economic conditions.

[0004] Existing wastewater treatment methods typically rely on filtration through filters.

While this traditional method can initially intercept larger suspended particles and impurities, it cannot perform deep treatments such as photocatalytic oxidation. Furthermore, it falls short in dealing with certain recalcitrant organic pollutants and fails to achieve the desired treatment results.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a photocatalytic oxidation device based on a multi-layer mesh catalyst carrier, comprising a housing, a filter photocatalytic component connected to the top of one side of the housing, the filter photocatalytic component including a feeding channel, a feeding port connected to the top of the feeding channel, a magnetic support frame provided on the inner wall of the feeding channel, a connecting frame connected to the top surface of the magnetic support frame, a catalyst carrier body provided inside the connecting frame, a first filter screen connected to the top of the catalyst carrier body, a second filter screen connected to the top of the first filter screen, an ultraviolet lamp provided inside the housing, and a glass panel provided on the top of the housing.

[0007] Furthermore, the connecting frame and the magnetic support frame form a magnetic connection, and the catalyst carrier body, the first filter screen, and the second filter screen are all fixed inside the connecting frame by bolts.

[0008] Furthermore, the outer surface of the connecting frame is in contact with the inner wall of the feeding channel.

[0009] Furthermore, a stirring assembly is connected to the bottom of the box, the stirring assembly includes a stirring motor, and a first pulley is connected to the top of the stirring motor.

[0010] Furthermore, a stirring rod is connected to the top of the first pulley, a drive belt is connected to the surface of the first pulley, and a second pulley is connected to one side of the drive belt.

[0011] Furthermore, the stirring motor is electrically connected to an external power source via a control switch, and the output end of the stirring motor is fixedly connected to the first pulley.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, when filtering wastewater, impurities can be filtered through the first and second filter screens first, and then the wastewater can enter the tank after passing through the catalyst carrier body. After that, the ultraviolet lamp can be turned on to perform photocatalysis on the wastewater. This avoids the problem that traditional filtration methods are ineffective when dealing with recalcitrant organic pollutants, and improves the wastewater treatment effect.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figure 1 - Figure 3 As shown, this utility model provides a photocatalytic oxidation device based on a multi-layered mesh catalyst carrier, including a housing 1. A filter photocatalytic component 2 is connected to the top of one side of the housing 1. The filter photocatalytic component 2 includes a feed channel 201, a feed inlet 202 connected to the top of the feed channel 201, a magnetic support frame 204 provided on the inner wall of the feed channel 201, a connecting frame 205 connected to the top surface of the magnetic support frame 204, and a catalyst carrier body 206 disposed inside the connecting frame 205. The top of the body 206 is connected to a first filter screen 207, and the top of the first filter screen 207 is connected to a second filter screen 208. An ultraviolet lamp 203 is installed inside the box 1, and a glass 209 is installed on the top of the box 1. The connecting frame 205 and the magnetic support frame 204 are magnetically connected. The catalyst carrier body 206, the first filter screen 207 and the second filter screen 208 are all fixed inside the connecting frame 205 by bolts. The outer surface of the connecting frame 205 is in contact with the inner wall of the feed channel 201.

[0023] The overall effect of Embodiment 1 is that, when treating wastewater, the wastewater can be poured into the feed channel 201 through the inlet 202, filtered by the first filter screen 207 and the second filter screen 208, then catalyzed by the catalyst carrier body 206, and finally enters the tank 1. The ultraviolet lamp 203 inside the tank 1 can achieve photocatalysis of the wastewater. When replacing the catalyst carrier body 206, the first filter screen 207 and the second filter screen 208, after turning off the ultraviolet lamp 203, it can be pulled upwards to remove the connecting frame 205 from the surface of the magnetic support frame 204. Then, the bolts can be unscrewed, and the catalyst carrier body 206, the first filter screen 207 and the second filter screen 208 can be replaced in sequence. The replaced connecting frame 205 can be pushed directly into the feed channel 201 and magnetically fixed to the magnetic support frame 204. This avoids the problem that traditional filtration methods are inadequate when dealing with recalcitrant organic pollutants, and improves the wastewater treatment effect.

[0024] Example 2, as Figure 1 and Figure 4 As shown, a stirring assembly 3 is connected to the bottom of the housing 1. The stirring assembly 3 includes a stirring motor 301. A first pulley 302 is connected to the top of the stirring motor 301. A stirring rod 303 is connected to the top of the first pulley 302. A transmission belt 304 is connected to the surface of the first pulley 302. A second pulley 305 is connected to one side of the transmission belt 304. The stirring motor 301 is electrically connected to an external power source through a control switch. The output end of the stirring motor 301 is fixedly connected to the first pulley 302.

[0025] The effect achieved by the entire embodiment 2 is that when the sewage enters the tank 1, the stirring motor 301 can be turned on to drive the first pulley 302 to rotate through the output end, thereby causing the first set of first pulleys 302 to rotate. At the same time, the second pulley 305, under the action of the transmission belt 304, will also drive the second set of stirring rods 303 to rotate, thereby realizing the stirring of the wastewater in the tank 1 and improving the photocatalytic effect of the ultraviolet lamp 203 on the wastewater.

[0026] Working principle: When filtering wastewater, impurities are first filtered through the first filter screen 207 and the second filter screen 208, and then the wastewater enters the tank 1 after passing through the catalyst carrier body 206. After that, the ultraviolet lamp 203 is turned on to perform photocatalysis on the wastewater. This avoids the problem that traditional filtration methods are ineffective when dealing with recalcitrant organic pollutants, and improves the wastewater treatment effect. After the wastewater enters the tank 1, the stirring motor 301 can be turned on to drive the two sets of stirring rods 303 to stir the wastewater in the tank 1, thereby improving the photocatalytic effect of the ultraviolet lamp 203 on the wastewater.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
