DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the embodiment, Figure 1-5 Provided is a three-dimensional electrode framework structure for electrocatalytic oxidation degradation treatment of wastewater, comprising:

[0031] The electrolysis box 1 is hollow and has a water inlet 2 and a water outlet 3 on two opposite sides in the transverse direction;

[0032] The design of the water inlet 2 and the water outlet 3 helps to simplify the process of sewage and wastewater in and out, improves the treatment efficiency, and makes the system operation more convenient;

[0033] A partition 4 is used to divide the internal space of the electrolytic box 1 into a plurality of electrolytic cells 5;

[0034] The partition 4 divides the internal space of the electrolytic box 1 into a plurality of electrolytic cells 5, and the electrolytic cells 5 can be manually selected to fill the internal space horizontally or vertically according to the internal space of the electrolytic box 1. Each electrolytic cell 5 can independently perform electrochemical reactions, thereby increasing the processing capacity of the system;

[0035] The partition plate 4 is provided with a flow-conducting connection hole 16 for connecting the electrolytic cells 5 at adjacent odd and even number positions;

[0036] The provision of the flow-guiding connection holes 16 helps to optimize the distribution of water flow among the multiple electrolytic cells 5, ensuring that each electrolytic cell 5 can obtain appropriate water flow, thereby improving the treatment efficiency;

[0037] A support platform 6 is provided in the electrolytic cell 5;

[0038] A frame 7 is disposed on the supporting platform 6 and has a plurality of guide grooves 8;

[0039] The design of the support platform 6 and the frame 7 provides a stable electrode installation foundation, which helps to maintain the appropriate distance and arrangement between the electrodes, thereby ensuring the stability of the electrocatalytic oxidation process. The design of the frame 7 allows for convenient replacement and maintenance of the electrodes, reducing maintenance costs and time.

[0040] A plurality of anode groups 9 and cathode groups 10 are arranged alternately and spaced apart in the plurality of guide grooves 8;

[0041] The design of the anode group and cathode group arranged alternately in the multiple guide grooves 8 increases the effective area of ​​the electrode and improves the rate and efficiency of the electrochemical reaction;

[0042] It also includes an external power supply, which is connected to the anode group 9 and the cathode group 10 and energized, so that an electric field is formed between the anode group 9 and the cathode group 10. Under the energized condition, the anode group 9 undergoes an oxidation reaction to oxidize the organic pollutants into harmless substances; the cathode group 10 undergoes a reduction reaction, which helps to reduce certain difficult-to-degrade organic matter, and promotes the pollutants in the wastewater to undergo an electrocatalytic reaction on the electrode surface. After the electrocatalytic oxidation-reduction reaction, the organic pollutants in the wastewater are degraded, thereby reducing COD. This is the principle of electrochemical reaction, and its specific structure is not marked in the attached drawings;

[0043] More specifically, the anode group 9 and the cathode group 10 each include an electrode body, a particle electrode and an insulator. The particle electrode is filled in the insulator, and the electrode body is inserted in the particle electrode.

[0044] Further, the frame 7 includes a plurality of frames 71, at least one frame 71 is provided in one electrolytic cell 5, a plurality of insertion guide blocks 72 are provided in the frame 71 at intervals along the lateral direction, and a guide groove 8 is formed between adjacent insertion guide blocks 72, and the frame 71 is made of plastic or metal treated with acid and alkali resistance;

[0045] By inserting the guide block 72 and the guide groove 8 for placing the electrode group, the number of electrodes can be effectively configured, and the arrangement and density of the electrodes can be adjusted according to actual processing requirements to adapt to different processing conditions. The hollow design of the insert guide block 72, the guide groove 8 and the frame 71 helps to improve the flow distribution of the electrolyte. The spacing setting of the frame 71 and the insert guide block 72 optimizes the space utilization, so that the space inside the electrolysis box 1 is more effectively utilized. At the same time, it also helps to maintain effective fluid dynamics in the electrolytic cell, ensuring that the electrolyte can evenly cover the entire electrode surface, thereby improving the efficiency of the electrocatalytic oxidation reaction.

[0046] Further, the height of the water inlet 2 is higher than the height of the water outlet 3, the number of electrolytic boxes 1 is multiple and they are arranged horizontally, the height of the water inlet 2 of the electrolytic box 1 at the front position is higher than the height of the water inlet 2 of the electrolytic box 1 at the rear position; the water outlets of the electrolytic cells 5 at odd positions (that is, the diversion connection holes 16 of the electrolytic cells at adjacent odd and even positions) are on the same horizontal plane;

[0047] The design that the water inlet 2 is higher than the water outlet 3 helps to maintain the natural flow of water and avoid backflow in the system, thereby improving the treatment efficiency. The design that the water inlet 2 of the front electrolysis box 1 is higher than that of the rear electrolysis box helps to achieve uniform distribution of water in the system, ensuring that each electrolysis box 1 can obtain appropriate water flow, thereby improving the overall treatment effect. Figure 5 The lateral arrangement design of the special-shaped pipe 17 connecting the water outlet 3 and the water inlet 2 of two adjacent electrolysis boxes 1 increases the processing capacity of the system and also improves the adaptability of the system. The number of electrolysis boxes can be increased or decreased as needed, which helps to maintain the stable flow of sewage and wastewater in the system and reduce the decline in treatment effect due to unstable flow.

[0048] Furthermore, the top of the electrolytic box 1 is open and the number of openings corresponds to the electrolytic cell 5. The top opening of the electrolytic box 1 is provided with a cover plate 11, and the upper and lower parts of the electrolytic box 1 are respectively provided with an exhaust port 12 and a sludge outlet 13;

[0049] The top opening and the cover plate 11 are used together to facilitate inspection and maintenance of the interior of the electrolytic box, replacement and maintenance of the electrodes, and can effectively seal the electrolytic box while protecting the electrodes from the external environment.

[0050] The exhaust port 12 and the sludge outlet 13 can be used to treat the gas, sludge and wastewater generated during the discharge process.

[0051] Furthermore, it also includes an aeration pipeline 14 , which is arranged on the supporting platform 6 and one end of which passes through the electrolysis box 1 , and an aeration plate 15 facing the frame 7 is arranged on the aeration pipeline 14 .

[0052] The design of the aeration pipeline 14 and the aeration plate 15 helps to evenly distribute oxygen to each electrode of the frame 7, optimizes the gas flow path, reduces the accumulation of bubbles on the electrode surface, and improves the gas utilization efficiency, thereby enhancing the rate and efficiency of the electrocatalytic oxidation reaction and improving the overall sewage and wastewater treatment effect;

[0053] Furthermore, the support platform 6 includes a first support platform 61 and a second support platform 62 which are arranged up and down and spaced apart from each other. The first support platform 61 is provided with a frame 7, and the second support platform 62 is provided with an aeration pipeline 14 and an aeration plate 15.

[0054] The supporting platform 6 provides a stable installation foundation for the aeration pipeline and the aeration disk, thereby enhancing the overall stability of the system.

[0055] Working principle:

[0056] Step 1: The wastewater first enters through the water inlet 2 of the electrolysis box 1. The height of the water inlet 2 is designed to be higher than the water outlet 3. The wastewater in the electrolysis box 1 flows naturally toward the water outlet 3. The naturally flowing wastewater passes through multiple electrolytic cells 5 and flows to the next electrolytic cell 5 through the guide connection hole 16 on the partition 4;

[0057] Step 2: The frame 7 located on the supporting platform 6 has anode groups 9 and cathode groups 10 alternately arranged in the guide groove 8 to perform electrochemical reaction on the flowing sewage and wastewater, and cooperates with the aeration pipeline 14 and the aeration plate 15 to provide oxygen to the anode group 9 and the cathode group 10 to enhance the electrochemical reaction effect and help suspend and remove the sludge;

[0058] Step 3: The exhaust port 12 and the sludge outlet 13 are respectively provided at the upper and lower parts of the electrolysis box 1. This design helps to discharge the gas generated during the treatment process in time, and at the same time facilitates the separation of sludge and wastewater. The treated water is discharged from the water outlet 3, and the treatment operation is completed;

[0059] When the sewage discharged from the water outlet 3 of the equipment is far below / higher than the discharge standard, it can be flexibly controlled by adding or reducing frames, electrode groups / connecting a second electrolysis box 1 in series.
