[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] Figures 1 to 4A bipolar pulsed electrochemically coupled microbial denitrification biotower includes a stainless steel or fiberglass tank 10. Multiple biological carriers 21 are suspended from the inner wall of the tank 10 by ropes 20, and an aeration pipe 50 is mounted at the bottom. The top of the tank 10 has an inlet 101 and an outlet 102, and a partition 12 is installed on the inner wall. The inlet 101 and outlet 102 are respectively located on both sides of the partition 12. The tank 10 is connected to a first circulation pump 30 and a second circulation pump 40. The aeration pipe 50 is connected to a submersible pump 60, which is connected to an air pump 70. The air pump 70 and the submersible pump 60 are connected to a controller 80. The tank 10 has a cylindrical or square structure.

[0024] Furthermore, the air pump 70 is equipped with a solenoid valve 71, which is connected to the submersible pump 60 via an air inlet pipe 64. The submersible pump 60 has a drain outlet 65, and a pressure sensor 81 is installed at the drain outlet 65. The pressure sensor 81 is electrically connected to the controller 80. The pressure sensor 81 detects the pressure at the drain outlet, and the solenoid valve adjusts the air intake. The submersible pump 60 has, from bottom to top, a motor 61, a filter screen 62, and multiple impellers 63. The filter screen 62 is connected to the air inlet pipe 64. The motor drives the impellers to rotate. The filter screen is located in the middle of the deep well submersible pump. The air-water mixture is cut by the impeller and discharged as micro-nano bubbles.

[0025] Furthermore, multiple crossbeams 11 are installed on the inner wall of the tank 10, and multiple hanging ropes 20 are vertically hung on the crossbeams 11. Biological carriers 21 are hung on the hanging ropes 20. The biological carriers 21 have mesh openings 210 and are interlocking spherical structures. The biological carriers 21 are used for microbial reproduction and biofilm formation.

[0026] Furthermore, the aeration pipe 50 has a polygonal structure, with a branch pipe 51 in the middle. Multiple aeration heads 55 are fixedly connected to the outer wall of the aeration pipe 50. The aeration heads 55 are 600mm above the ground, arranged vertically at a 30° angle, totaling 8. The aeration heads on the branch pipe 51 are arranged horizontally in a staggered pattern, totaling 4. The aeration pipe can be pentagonal, hexagonal, or octagonal, with an octagonal shape being preferred. The branch pipe 51 is perpendicular to the partition.

[0027] Furthermore, the first circulation pump 30 is equipped with a first inlet pipe 32 and a first outlet pipe 31. The first inlet pipe 32 is connected to the inner bottom end of the tank 10, and the first outlet pipe 31 is connected to the top end of the tank 10. The second circulation pump 40 is equipped with a second inlet pipe 42 and a second outlet pipe 41. The second inlet pipe 42 is connected to the inner bottom end of the tank 10, and the second outlet pipe 41 is connected to the top end of the tank 10. The circulation pumps pump the sewage from the bottom of the tank to the top of the tank, allowing the biological carrier to fully attach and reproduce, thereby improving the sewage treatment efficiency.

[0028] The air pump and the deep well submersible pump are turned on simultaneously. The pressure sensor detects the outlet pressure, the solenoid valve adjusts the air pressure, the impeller cuts the water bubbles into microbubbles, and the microbubbles enter the tank through the aeration head to supply oxygen to the biological carrier. The sewage enters the tank from the inlet 101 and forms a biofilm on the biological carrier. The circulation pump makes the sewage in the tank circulate internally to improve the treatment efficiency. The treated water is discharged from the biological tower from the outlet 102.

[0029] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
