[0002] Biological packing cages form a biofilm on the surface of the packing material, which utilizes the metabolism of microorganisms to decompose pollutants such as organic matter, ammonia nitrogen, and total phosphorus in the water. They are widely used in sewage treatment plants, industrial wastewater treatment, and natural water body restoration.

[0003] Chinese utility model patent CN216377658U discloses a novel suspended biological packing cage for water treatment: it includes a buoyancy device, a floating bed, and a gravity regulating pipe. Suspended packing is suspended on the floating bed and suspended in the gaps of the floating bed by suspension ropes. The lower end of the suspended packing is fixedly connected to the gravity regulating pipe. The buoyancy device is fixedly connected around the floating bed. The four corners of the buoyancy device are fixedly connected with buoyancy device connecting ears. A plant planting pot is fixed in the middle space of the buoyancy device.

[0004] However, existing technologies still have shortcomings:

[0005] 1. Suspended packing is suspended in the gaps of the floating bed by suspension ropes, which can easily lead to uneven distribution of packing and affect the film formation efficiency.

[0006] 2. The plant pots are fixed inside the buoyancy device, and the suspended filler is fixed on the gravity adjustment pipe. The lack of modularity affects the maintenance and use of the device. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figure 1-4As shown, a water treatment suspended biological packing cage includes a floating bed 1 with a through hole 14 in the middle. A planting pot 5 is detachably installed in the through hole 14. Specifically, a limiting component is fixedly installed in the through hole 14, and the planting pot 5 is tightly installed in the limiting component. The limiting component includes a limiting ring 11, a cable connecting seat 12, and a limiting spring 13. The limiting ring 11 is fixedly installed on the through hole 14, and the cable connecting seat 12 and the limiting spring 13 are fixedly connected to the limiting ring 11. Several cable connecting seats 12 and limiting spring 13 are provided and are equidistantly arranged on the limiting ring 11. The cable connecting seat 12 is located in the through hole 14. 4. At the upper end, the cable connecting seat 12 is used to bind the cable and tie the other end of the cable to the shore to achieve the initial positioning of the device. The limiting spring 13 is set in the through hole 14. The planting pot 5 is pressed into the limiting spring 13 to achieve the positioning of the planting pot 5. The planting pot 5 is used to plant plants such as foxtail algae. The lower end of the planting pot 5 is provided with several root-penetrating holes 16. The side of the planting pot 5 is provided with several water exchange holes 15. The floating bed 1 is provided with several limiting grooves 2 to facilitate the placement of the limiting rod, which helps to achieve the overall positioning of the device on the riverbed and also helps to reduce the weight of the floating bed 1. The floating bed 1 is provided with a buoyancy cavity 18.

[0028] As one embodiment of this example, a counterweight box 6 is provided below the floating bed 1, and several suspension ropes 8 are equidistantly arranged between the floating bed 1 and the counterweight box 6. Specifically, several universal rings 7 are fixedly arranged below the floating bed 1 and above the counterweight box 6. The connecting base of the universal rings 7 is threadedly connected to the floating bed 1 and the counterweight box 6 through nuts and washers. The rotating connectors of the universal rings 7 on the floating bed 1 and the counterweight box 6 are correspondingly arranged. Both ends of the suspension ropes 8 are fixedly installed with lifting rings 10, which are suspended on the universal rings 7, that is, connected to the universal rings 7 on the floating bed 1 and the counterweight box 6 respectively. The suspension ropes 8 are covered with spiral composite packing 9, and both ends of the spiral composite packing 9 are fixedly connected to the lifting rings 10. The spiral composite packing 9 is a three-dimensional spring structure woven from polypropylene and carbon fiber composite filaments. The spiral packing forms a three-dimensional transmission, which increases the utilization rate of dissolved oxygen in the water. The surface of the spiral composite packing 9 is covered with a nano-hydrophilic coating. When in use, the hydrophilic coating works synergistically with the dynamic water flow to delay the excessive proliferation of biofilm, thereby extending the maintenance cycle.

[0029] As one embodiment of this example, a water inlet 17 is fixedly provided on the counterweight box 6. Water can be injected into the counterweight box 6 through the water inlet 17 to adjust the counterweight of the device. A cover is detachably provided on the water inlet 17.

[0030] As one implementation method in this embodiment, the floating bed 1 is equilateral hexagonal, and the side of the floating bed 1 is provided with a locking structure to facilitate the splicing of several floating beds 1, which can be spliced ​​into a honeycomb-shaped floating island. Specifically, the locking structure includes a locking seat 3 and a locking block 4; three locking seats 3 and locking blocks 4 are fixedly arranged at intervals on the side of the floating bed 1. By locking the locking seats 3 and locking blocks 4 on different floating beds 1, the splicing of multiple floating beds 1 can be realized.

[0031] Working principle:

[0032] Plant foxtail algae in planting pot 5, press planting pot 5 into the limiting component in through hole 14, place the whole component in the water body to be treated, inject water into counterweight box 6 through water inlet 17, adjust the counterweight of the device so that the device floats on the water surface and the spiral composite packing 9 is located in the underwater area of ​​0.5-2m. The roots of foxtail algae grow downward and form a three-dimensional ecological niche with the spiral composite packing 9, which works together to degrade pollutants in the water. When the spiral composite packing 9 needs to be replaced, release the limiting of lifting ring 10 and universal ring 7 to detach the spiral composite packing 9 from floating bed 1 and counterweight box 6, so as to facilitate the replacement of spiral composite packing 9.
