[0031] The electrolytic anode 403 and the electrolytic cathode 404 are detachably connected to the anode electrolytic cell 401 and the cathode electrolytic cell 402 respectively through detachable components.

[0032] Please refer to Figure 2 The anode electrolytic cell 401 and the cathode electrolytic cell 402 are arranged in sequence inside the treatment cell 1 from left to right, and the output end of the treatment cell liquid inlet pipe 2 is connected to the input end of the anode electrolytic cell 401, and the input end of the treatment cell liquid outlet pipe 3 is connected to the output end of the cathode electrolytic cell 402.

[0033] In this embodiment, the multiple electrolytic anodes 403 installed in the anode electrolytic cell 401 perform anodic decomposition treatment on the waste liquid containing nitrate ions, and the multiple electrolytic cathodes 404 installed in the cathode electrolytic cell 402 perform cathodic decomposition treatment on the waste liquid containing nitrate ions.

[0034] Please refer to Figure 2 The transport assembly includes an anode electrolytic cell outlet pipe 406, a cathode electrolytic cell outlet pipe 407, a water pump 408, a first connecting pipe 409 and a second connecting pipe 4010;

[0035] The anode electrolytic cell liquid outlet pipe 406 is fixedly connected to the output end of the anode electrolytic cell 401 and passes through the outside of the treatment cell 1. The cathode electrolytic cell liquid outlet pipe 407 is fixedly connected to the input end of the cathode electrolytic cell 402 and passes through the outside of the treatment cell 1. The water pump 408 is arranged on the outside of the treatment cell 1. The two ends of the first connecting pipe 409 are respectively connected to one docking end of the anode electrolytic cell liquid outlet pipe 406 and the water pump 408. The two ends of the second connecting pipe 4010 are respectively connected to the other docking end of the cathode electrolytic cell liquid outlet pipe 407 and the water pump 408.

[0036] In this embodiment: the water pump 408 is controlled by the controller to operate, so that the water pump 408 in the operating state extracts the waste liquid inside the anode electrolytic cell 401 through the anode electrolytic cell outlet pipe 406 and the first connecting pipe 409, and the water pump 408 in the operating state is used to transport the extracted waste liquid to the interior of the cathode electrolytic cell 402 through the cathode electrolytic cell outlet pipe 407 and the second connecting pipe 4010.

[0039] Please refer to Figure 3 , the disassembly and assembly components include two mounting frames 405 and a plurality of docking frames 4011, limiting slots 4012, insertion holes 4013, insertion rods 4014 and springs 4015;

[0040] The two mounting frames 405 are respectively fixedly connected to the top of the anode electrolytic cell 401 and the cathode electrolytic cell 402. The tops of the electrolytic anode 403 and the electrolytic cathode 404 are both fixedly connected with a docking frame 4011. The limiting groove 4012 is opened on the surface of the mounting frame 405. The socket 4013 is opened on one side of the mounting frame 405. The insertion rod 4014 is slidingly connected to the bent part of the docking frame 4011. The spring 4015 is sleeved on the outside of the socket 4013, and the two ends of the spring 4015 are respectively fixedly connected to the bent part of the docking frame 4011 and the protrusion of the socket 4013.

[0041] In this embodiment, when multiple electrolytic anodes 403 and electrolytic cathodes 404 are installed, the rod 4014 is pulled outward, and the rod 4014 in the outward moving state stretches the spring 4015. Then, the electrolytic anode 403 is inserted into the limiting groove 4012 of a mounting frame 405, so that the rod 4014 is aligned with the socket 4013, and then the rod 4014 is loosened, so that the spring 4015 in the reset state drives the rod 4014 to move inward. When the insertion rod 4014 in the inner moving state is inserted into the socket 4013, the socket 4013 and the insertion rod 4014 in the engaged state limit the position of the electrolytic anode 403, and then the electrolytic anode 403 is installed in the limiting groove 4012 of one mounting bracket 405. As described above, the electrolytic cathode 404 is installed in the limiting groove 4012 of another mounting bracket 405, and multiple electrolytic anodes 403 and electrolytic cathodes 404 are installed in sequence.

[0042] Please refer to Figure 3 The electrolytic anode 403 is detachably connected to one mounting bracket 405 , and the electrolytic cathode 404 is detachably connected to another mounting bracket 405 .

[0043] In this embodiment, multiple electrolytic anodes 403 are sequentially mounted on one mounting rack 405 , and multiple electrolytic anodes 403 are completely installed inside the anode electrolytic cell 401 , and multiple electrolytic cathodes 404 are sequentially mounted on another mounting rack 405 , and multiple electrolytic cathodes 404 are completely installed inside the cathode electrolytic cell 402 .

[0044] Please refer to Figure 3 The inner walls of the anode electrolytic cell 401 and the cathode electrolytic cell 402 are both provided with electrolyte monitors 5, and the two electrolyte monitors 5 are used to detect the waste liquid inside the anode electrolytic cell 401 and the cathode electrolytic cell 402 respectively.

[0045] In this embodiment, when a receiving end of an electrolyte monitor 5 provided on the inner wall of the anode electrolytic cell 401 detects that the decomposition of the waste liquid inside the anode electrolytic cell 401 is complete, a transmitting end of the electrolyte monitor 5 transmits the signal to the controller, and the controller then controls the water pump 408 to operate.

[0046] Working principle: First, multiple electrolytic anodes 403 and electrolytic cathodes 404 are installed, and the rod 4014 is pulled outward. The rod 4014 in the outward moving state stretches the spring 4015. Then, the electrolytic anode 403 is inserted into the limiting groove 4012 of a mounting frame 405, so that the rod 4014 is aligned with the socket 4013. Then, the rod 4014 is loosened, and the spring 4015 in the reset state drives the rod 4014 to move inward. When the inserted rod 4014 in the inwardly moving state is inserted into the socket 4013, the socket 4013 and the inserted rod 4014 in the engaged state limit the position of the electrolytic anode 403, thereby completing the installation of the electrolytic anode 403 in the limiting groove 4012 of one mounting bracket 405. As described above, the electrolytic cathode 404 is installed in the limiting groove 4012 of the other mounting bracket 405. Multiple electrolytic anodes 403 and electrolytic cathodes 404 are installed in sequence.

[0047] At this time, the waste liquid containing nitrate radicals is flowed into the inside of the anode electrolytic cell 401 through the liquid inlet pipe 2 of the treatment pool, so that the multiple electrolytic anodes 403 installed in the anode electrolytic cell 401 perform anodic decomposition treatment on the waste liquid containing nitrate radicals. When the receiving end of an electrolyte monitor 5 set on the inner wall of the anode electrolytic cell 401 detects that the waste liquid inside the anode electrolytic cell 401 has been decomposed, the transmitting end of an electrolyte monitor 5 transmits this signal to the controller, and the controller controls the water pump 408 to operate, so that the running water pump 408 pumps the waste liquid inside the anode electrolytic cell 401 through the anode electrolytic cell outlet pipe 406 and the first connecting pipe 409. When the waste liquid is discharged, the water pump 408 in operation is used to transport the extracted waste liquid to the interior of the cathode electrolytic cell 402 through the cathode electrolytic cell outlet pipe 407 and the second connecting pipe 4010, and then the multiple electrolytic cathodes 404 installed inside the cathode electrolytic cell 402 perform cathode decomposition treatment on the waste liquid containing nitrate ions. When the receiving end of another electrolyte monitor 5 set on the inner wall of the cathode electrolytic cell 402 detects that the decomposition of the waste liquid inside the cathode electrolytic cell 402 is completed, the treated waste liquid is discharged to the outside of the treatment cell 1 through the treatment cell outlet pipe 3, so that the nitrate ions in the waste liquid are effectively decomposed through the above structure, so that the nitrate ions are significantly reduced or removed.
