The fixing block 5 is slidably connected in the fixing groove 28 for easy fixing.

[0034] The regulating assembly includes a three-way pipe 13, with connecting hoses 14 fixedly connected to both ends of the three-way pipe 13. A filter chamber 12 is provided on the top of the treatment box 1, with two sets of filter chambers 12. One end of each set of connecting hoses 14 passes through the top cover 2 and is located within one set of filter chambers 12. Solenoid valves 15 are connected to each set of connecting hoses 14. A partition plate 29 is fixedly connected to the inner wall of the top of the treatment box 1, with flow rate sensors fixedly connected to both sides of the partition plate 29. Four sets of flow rate sensors are provided. A controller 16 is fixedly connected to the outer wall of the treatment box 1, with the solenoid valves 15 and flow rate sensors electrically connected to the controller 16. An activated carbon plate 18 and a partition plate 19 are fixedly connected to the inner wall of the treatment box 1. An aeration pipe 20 is connected to the top of the partition plate 19, with multiple sets of aeration pipes 20 connected to each other. An air pump 26 is fixedly connected to the side of the treatment box 1 by bolts, with the air outlet of the air pump 26 connected to the aeration pipe 20 via a hose. The bottom of the partition plate 19 is fixed... A second baffle 24 is connected to the bottom of the treatment box 1, and a first baffle 22 and a third baffle 30 are fixedly connected to it. One side of the first baffle 22 is fixedly connected to the second baffle 24. The top of the first baffle 22 has a through hole 23, and there are multiple sets of through holes 23. Ultraviolet lamps 25 are connected to the inner wall of the treatment box 1, the side of the first baffle 22, and the side of the third baffle 30. There are multiple sets of ultraviolet lamps 25, and the ultraviolet lamps 25 are electrically connected to the controller 16. An observation window 17 is connected to the outer wall of the treatment box 1. A water pump 27 is fixedly connected to the bottom of the side of the treatment box 1. The inlet of the water pump 27 is connected to an inlet pipe, which extends into the treatment box 1 on the side away from the first baffle 22. A buffer chamber 21 is provided in the treatment box 1, which allows water flowing down from above to slowly enter the subsequent disinfection module. The buffer chamber 21 is located between the side of the first baffle 22 away from the third baffle 30 and the treatment box 1. The locking block 10 is set in a right-angled triangle for easy unidirectional limiting.

[0035] Working principle: Pulling the pull plate 31 outward from the protective frame 7 causes the locking block 10 to slide out from the locking groove 6, allowing the fixing block 5 to slide out from the fixing groove 28. This facilitates the disassembly of the filter frames 4 on both sides to clean the collected debris and feces, preventing clogging of the filter holes and affecting subsequent water treatment. When installing the filter frame 4 after cleaning, slide the filter frame 4 into the sliding groove 3, causing the fixing block 5 to slide into the fixing groove 28. The fixing block 5 and the locking block 10 slide at an angle, pressing the locking block 10 to slide in the square groove. At the same time, the locking block 10 presses the spring 11. When the locking groove 6 and the locking block 10 are aligned... When the filter frame 4 is aligned, the spring 11 causes the locking block 10 to slide into the locking groove 6, limiting the fixing block 5 and completing the installation. Water is then injected into the filter chambers 12 on both sides through the connecting hoses 14 on both sides of the pipe connected to the top of the tee pipe 13. Two sets of flow rate sensors are connected to both sides of the partition plate 29, with the two sets of flow rate sensors on the same side positioned above and below the filter frame 4 respectively. These sensors detect the difference in water flow velocity before and after passing through each filter frame 4, thus reflecting the degree of blockage in the filter frame 4 and facilitating the detection of blockages in the filter frames 4 on both sides. In case of blockage, when one set of filter frames 4 becomes severely blocked (i.e., the difference between the upper and lower flow rate sensors on one side exceeds the preset value in the controller 16), the controller 16 can control the solenoid valve 15 of the corresponding set to close, and then remove the corresponding set of filter frames 4 from the treatment tank 1 for cleaning. This operation does not require stopping the machine, making it more convenient. Wastewater passes through the filter frames 4 to filter out debris and feces, then passes through the activated carbon plate 18 below to adsorb odors, and then flows above the baffle 19. By turning on the air pump 26, multiple aeration pipes 20 are activated to aerate the wastewater, allowing the installed biological suspended packing to better function. The wastewater undergoes a biochemical reaction with the aquaculture wastewater. The treated water passes through a partition 19, which has multiple sets of micropores in the area corresponding to the buffer chamber 21, allowing water to enter the buffer chamber 21. When the water in the buffer chamber 21 accumulates and rises, it flows through the through hole 23 into the area to the left of the first baffle 22 for disinfection. The water passes through the area between the first baffle 22, the second baffle 24, and the third baffle 30, where multiple sets of ultraviolet lamps 25 perform disinfection. When the water reaches the side of the third baffle 30 away from the buffer chamber 21, it is injected into the aquaculture pond for use through the pipe connected to the water pump 27.
