The water inlet box 601 is fixedly connected to the top of the fixed column 5, and the top of the water inlet box 601 is connected to the multi-stage filter screen 602 by screw threads. The top of the water inlet box 601 is connected to the fixing cover 603 by screw threads on all sides. The bottom of the water inlet box 601 is connected with the connecting pipe 604, and the top of the fixed cover 603 is connected with the water inlet pipe 605.

[0023] Specifically, the top of the fixed base plate 1 is fixedly connected with the pH value regulating tank 7 , and the side of the connecting pipe 604 is penetrated and connected with the pH value regulating tank 7 .

[0024] In this embodiment, the pH adjustment tank 7 can ensure that the regulator and water are fully mixed, and maintain the uniformity and stability of the pH value.

[0025] Specifically, a micro-electrolysis reaction tank 8 is connected through the side of the pH value adjustment tank 7 , and a circulation pump 9 is connected through the side of the micro-electrolysis reaction tank 8 .

[0026] In this embodiment, the micro-electrolysis reaction tank 8 can reduce the concentration of harmful substances in water, promote the degradation of organic pollutants, and improve the quality of treated water through micro-electrolysis technology.

[0027] Specifically, a liquid infusion tube 10 is connected through the side of the circulation pump 9, a Fenton oxidation tank 2 is connected through the side of the liquid infusion tube 10, and a fixed base plate 1 is connected to the bottom of the circulation pump 9 through screw threads.

[0028] In this embodiment, the Fenton oxidation tank 2 provides a space for the ferrous salt and hydrogen peroxide to mix and react, so that these chemical reactions can be carried out efficiently.

[0031] In this embodiment, the inclined tube sedimentation tank 13 improves the sedimentation efficiency through the design of the inclined tube.

[0035] In the Fenton oxidation tank 2, hydrogen peroxide is mixed with ferrous salt to react and generate hydroxyl radicals. This is an exothermic reaction that generates a large amount of heat. The increase in temperature may cause the reaction rate to accelerate and even trigger an uncontrollable reaction. The heat dissipation structure can help maintain the temperature in the reactor within a controllable range to prevent overheating.

[0036] In summary, in this circulating treatment device based on room-temperature Fenton advanced oxidation, through the arrangement of the connecting mechanism 3, the heat dissipation mechanism 4 and the filtering mechanism 6, the multi-stage filter 602 can effectively remove solid particles and other impurities in the wastewater, prevent these impurities from causing wear and corrosion to the reaction equipment and other connected equipment, and extend their service life. At the same time, it can significantly reduce the sediment inside the reaction equipment and pipelines, avoid equipment failure or damage caused by solid particles, thereby reducing the cost of repairing and replacing equipment. The threaded connection structure also facilitates the subsequent removal and replacement of the multi-stage filter 602 by personnel. The installation of heat dissipation fins 302 on the outside of the Fenton oxidation tank 2 can increase the heat dissipation area. The heat dissipation fan 404 can accelerate air flow, thereby more quickly removing the heat from the surface of the Fenton oxidation tank 2, maintaining the temperature inside the Fenton oxidation tank 2 within a controllable range, helping to maintain the stability of the reaction, preventing overheating and incomplete reaction or side reactions due to temperature fluctuations. At the same time, at a suitable temperature, the efficiency of the Fenton reaction is generally higher, and pollutants can be degraded faster.
