[0002] "Industrial wastewater" refers to wastewater generated during industrial production that contains various pollutants. These pollutants may include chemicals, heavy metals, oils, suspended solids, and organic matter. Due to the complex composition of industrial wastewater, improper treatment can have serious impacts on the environment and human health. Therefore, industrial wastewater must undergo rigorous treatment and purification to meet national or local discharge standards before it can be discharged into natural water bodies or municipal pipe networks. Common treatment methods include physical, chemical, and biological methods.

[0003] The existing Chinese patent application number is 202321053766.7, and the publication number is CN220034188U. It is a catalytic oxidation industrial wastewater treatment device. The following technical solution is proposed: it includes a sewage treatment tank and a sealed top cover connected to its upper end. The upper end of the sealed top cover is provided with a water inlet pipe. A rotating drum is rotatably connected to the sealed top cover. The rotating drum is provided with an air inlet pipe extending to the bottom of the sewage treatment tank. The outer side of the air inlet pipe is provided with multiple exhaust holes located inside the sewage treatment tank. The utility model adopts a pair of feeding mechanisms at the upper end of the sealed top cover. By adding a well-proportioned catalyst into the feed cover, the catalyst enters the interior of the sewage treatment tank through the feed pipe, and then the sealing cover is sealed to the feed cover, the catalyst can be quickly added. By providing multiple exhaust holes on the outer side of the air inlet pipe, ozone can be evenly introduced into the sewage treatment tank and fully contacted with the sewage, thereby improving the efficiency of the reaction.

In order to make the purpose, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0021] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model provides a technical solution of a multi-stage ozone catalytic oxidation industrial wastewater treatment device: it includes a shell 1, a multi-stage treatment component is arranged inside the shell 1, and the multi-stage treatment component is sequentially provided with a partition 1 31, a partition 2 32 and a partition 3 33 from top to bottom, a primary treatment chamber 301 is provided above the partition 1 31, a secondary treatment chamber 302 is provided between the partition 1 31 and the partition 2 32, and a tertiary treatment chamber 303 is provided between the partition 2 32 and the partition 3 33, an overflow pipe 34 is provided through the partition 1 31, the partition 2 32 and the partition 3 33, and an ozone generator 35 is installed on the partition 1 31, the partition 2 32 and the partition 3 33.

[0022] A liquid delivery pipe 11 is provided through the top of the shell 1 , and a solid delivery port 12 is also provided. An inspection port 14 is provided on the lower side of the shell 1 , and a drain pipe 15 is provided at the bottom of the shell 1 .

[0023] The solids inlet 12 and the inspection port 14 are both equipped with a cover plate 13, and a connecting assembly is provided on the cover plate 13. The connecting assembly includes a fixing base 21, which is mounted on the housing 1. A bracket 22 is rotatably connected to the fixing base 21. A stud 23 is provided at the end of the bracket 22, and the bottom end of the stud 23 is connected to the cover plate 13.

[0024] The stud 23 is slidably connected to the bracket 22 , and the stud 23 located on the top and bottom surfaces of the bracket 22 is externally threadedly connected to a nut 24 .

[0025] An online monitoring module is provided in the housing 1 for real-time monitoring of COD (chemical oxygen demand), BOD (biochemical oxygen demand) and pH value in the wastewater.

[0026] According to the above scheme, in this embodiment, wastewater first enters the primary treatment chamber 301 through the liquid delivery pipe 11. Within the primary treatment chamber, the wastewater comes into contact with the ozone generated by the ozone generator 35, initiating the initial oxidative decomposition process. Due to the provision of partition 1 31, once the wastewater reaches a certain height, it flows through the overflow pipe 34 into the secondary treatment chamber 302.

[0027] In the secondary treatment chamber 302, the wastewater is again exposed to ozone generated by the ozone generator 35 for further oxidation and decomposition. Similarly, after reaching the height of the second partition 32, the wastewater flows into the tertiary treatment chamber 303 through the overflow pipe 34.

[0028] The tertiary treatment chamber 303 is the final treatment stage, where the wastewater comes into contact with the ozone generated by the ozone generator 35 for the final time, ensuring that the pollutants in the wastewater are decomposed to the greatest extent possible. The treated wastewater is discharged from the device through the drain pipe 15.

[0029] The covers 13 of the solids inlet 12 and inspection port 14 are easily opened and closed via a connecting assembly, facilitating the delivery of solid chemicals and equipment maintenance. Covers 13 are opened and closed by rotating studs 23 on brackets 22. The studs 23 engage nuts 24 to secure the covers 13 securely.

[0030] The online monitoring module provides real-time monitoring of key wastewater indicators, such as COD, BOD, and pH. This data feed allows adjustments to the ozone generator to ensure optimal treatment results. Furthermore, the monitoring data can be recorded and analyzed to facilitate optimization and management of the entire treatment process.

[0031] In summary, the multi-stage ozone catalytic oxidation industrial wastewater treatment device of this utility model achieves progressively deeper wastewater treatment through its multi-stage treatment chamber design, significantly improving treatment efficiency and effectiveness. Furthermore, through real-time monitoring by the online monitoring module and the uniform distribution of ozone generators, precise control and optimization of the treatment process are ensured.
