The pull plate 117 is fixedly connected to the adsorption seat 115, and both partition plates 116 are fixedly connected to the adsorption seat 115. The adsorption seat 115 is movably connected to the sliding frame 113. Each foot post 120 and the drain pipe 119 are fixedly connected to the seat body 118, and the seat body 118 is fixedly connected to the filter body 112. The adsorption seat 115 in the adsorption assembly 108 can be freely slidably pulled out inside the filter body 112. Without affecting the advanced oxidation treatment and activated carbon adsorption of the equipment, the adsorption effect of the activated carbon block is maintained by timely replacement of the activated carbon block through the removal of the adsorption seat 115. This design is convenient to operate and easy to produce, and solves the problem that the adsorption effect of the activated carbon plate decreases after long-term use, making it inconvenient for staff to replace and limiting its use.

[0023] The adsorption component 108 is located inside the filter cylinder 107, which is located above the support base 101. The oxidation tank 106 is located at the upper end of the filter cylinder 107. The stirring motor 104 is located above the top cover 103, which is located above the oxidation tank 106. The reinforcing ring 114 further connects the tank body 109 and the filter body 112, maintaining a tight and airtight connection. The guide block 111 facilitates the smooth downward flow of water in the tank body 109, preventing water residue inside the tank body 109.

[0024] Secondly, the guide block 111 is located at the lower end of the tank 109, the permeable membrane 110 is located on the inner wall of the tank 109, the tank 109 is located at the upper end of the filter cylinder 107, the reinforcing ring 114 is located on the inner wall of the filter body 112, the sliding frame 113 is located on the inner side of the filter body 112, the filter body 112 is located above the support base 101, both partition plates 116 have multiple through holes, and the partition plate 116 located below the adsorption base 115 is positioned... The filter is fixed and not easy to disassemble. The partition 116 on the upper side of the adsorption seat 115 can be disassembled and removed. Therefore, it is convenient for the staff to remove the adsorption seat 115 from the inside of the sliding frame 113, and then remove the partition 116 above to replace the activated carbon block. Then the adsorption seat 115 can be placed directly inside the filter body 112 along the sliding frame 113. A sealing ring is provided between the adsorption seat 115 and the sliding frame 113 to prevent overflow during water processing.

[0025] Meanwhile, the drawer plate 117 is located on one side of the adsorption seat 115, and the two partition plates 116 are located on the upper and lower sides of the adsorption seat 115, respectively. The adsorption seat 115 is located inside the sliding frame 113. Each foot post 120 and the drain pipe 119 are located below the base body 118, which is located below the filter body 112. An automatic valve is provided at the outer end of the drain pipe 119. Multiple foot posts 120 support the base body 118 and the filter body 112. When the device is in use, industrial wastewater is injected through the water injection pipe on the top cover 103. The stirring motor 104 is started. After the wastewater enters the tank 109, it will first be initially filtered by the filter plate on the inner wall of the tank 109. Then, the wastewater is stirred and mixed by the stirring frame 105. The advanced oxidation equipment set on the inner and outer sides of the tank 109... The highly reactive hydroxyl radicals (・OH) generated in the reaction system attack organic pollutant molecules, decomposing them into small molecule organic matter, or directly oxidizing them into CO2, H2O, and other non-toxic small molecule acids, thereby reducing the concentration and toxicity of organic matter and improving the biodegradability of wastewater. The water enters the filter body 112 through the permeable membrane 110, and then passes through the two partitions 116 in sequence, and through the activated carbon blocks inside the two partitions 116. The wastewater after advanced oxidation treatment enters the activated carbon filter unit. The activated carbon adsorbs residual organic matter and unoxidized pollutants in the water on its surface and in its pores through adsorption, further removing impurities in the water and deeply purifying the water quality. At the same time, the activated carbon also has a certain adsorption effect on some small molecule oxidation products, which can improve the treatment effect. The completely treated water is then discharged through the drain pipe 119.

[0026] In this embodiment, the reinforcing ring 114 further connects the tank 109 and the filter body 112, maintaining the airtightness and tightness of their connection. The guide block 111 facilitates the smooth downward flow of water in the tank 109, preventing water residue inside the tank 109. Both partitions 116 have multiple through holes. The partition 116 located below the adsorption seat 115 is fixed in position and inconvenient to disassemble, while the partition 116 located above the adsorption seat 115 can be disassembled and removed. Therefore, it is convenient for workers to remove the adsorption seat 115 from the inside of the sliding frame 113, and then remove the upper partition 116 to process the activated carbon block. After replacement, the adsorption seat 115 is placed directly inside the filter body 112, conforming to the sliding frame 113. A sealing ring is provided between the adsorption seat 115 and the sliding frame 113 to prevent overflow during water processing. An automatic valve is provided at the outer end of the drain pipe 119. Multiple support columns 120 support the seat 118 and the filter body 112. When in use, industrial wastewater is injected through the water injection pipe on the top cover 103, and the stirring motor 104 is started, allowing the wastewater to enter the tank. After entering tank 109, the wastewater first undergoes preliminary filtration through the filter plates built into the inner wall of tank 109. Then, the wastewater is stirred and mixed by the stirring rack 105. The highly reactive hydroxyl radicals (・OH) generated in the advanced oxidation equipment reaction system located on both the inner and outer sides of tank 109 attack the organic pollutant molecules, decomposing them into smaller organic molecules or directly oxidizing them into CO2, H2O, and other non-toxic small-molecule acids. This reduces the concentration and toxicity of organic matter, improves the biodegradability of the wastewater, and the water then enters the permeable membrane 110. Within the filter body 112, the wastewater, after advanced oxidation treatment, passes through two partitions 116 and then through activated carbon blocks inside the partitions 116. The activated carbon adsorbs residual organic matter and unoxidized pollutants in the water onto its surface and within its pores, further removing impurities and achieving deep purification of the water. Simultaneously, the activated carbon also adsorbs some small-molecule oxidation products, improving the treatment effect. The completely treated water is then discharged through the drain pipe 119.
