Specifically, the other end of the rotating pipe 141 far from the water inlet pipe 15 may be closed, and the other end of the water distribution pipe 142 far from the rotating pipe 141 may also be closed, so as to ensure that all the water entering the water distribution pipe 142 through the rotating pipe 141 can flow out through the water distribution holes 1421 of the water distribution pipe 142.
In one embodiment, the rotating pipe 141 and the water distribution pipe 142 may be integrally formed to simplify the structure. In another embodiment, the rotating pipe 141 and the water distribution pipe 142 may be detachably connected to each other for subsequent maintenance.

Specifically, as shown in fig. 5, the sidewall of the first cylinder 11 may further have air outlets 112, and the third packing layer 21 does not cover the air outlets 112, for example, the upper surface of the third packing layer 21 may be located below the air outlets 112 to prevent the air outlets 112 from being blocked by the third packing layer 21.
In other embodiments, the air outlet 112 on the sidewall of the first cylinder 11 can also be located above the rotating water distributor 14 to prevent the water flowing out of the water distribution holes 1421 of the rotating water distributor 14 from flowing out of the air outlet 112 on the sidewall of the first cylinder 11 before entering the lower second cylinder 12.
In the above embodiment, as shown in fig. 5, a plurality of water distribution holes 161/181/201 may be respectively formed in the first, second and third packing support plates 16, 18 and 20, and the water distribution holes 161/181/201 may penetrate through the corresponding first, second or third packing support plates 16, 18 or 20 from top to bottom. Also, in practice, the first, second and third packing support plates 16, 18 and 20 may have the same shape and configuration.

So, make can be according to the concrete processing demand of aquaculture water, adjust the filler number of piles and the filler kind of different packing layers to reach the effect that the throughput is adjustable.
Specifically, the first, second, and third filler particles described above may be polyhedral hollow filler particles (e.g., polypropylene hollow spheres). The polyhedral hollow filler particles can separate water flow reaching the surface of the polyhedral hollow filler particles into a linear shape and a drop shape so as to increase the specific surface area of the water flow and enable the water to be fully contacted with air, thereby being beneficial to taking away carbon dioxide from the water by the air and improving the carbon dioxide removal effect.
In some embodiments, a biofilm may be further attached to the surfaces (including the inner surface and the outer surface) of the first filler particles, the second filler particles and the third filler particles, so that the first filler layer 17, the second filler layer 19 and the third filler layer 21 may also have a function of purifying water.
Also, it will be appreciated that the first, second, and third packing support plates 16, 18, 20 described above should have sufficient strength and rigidity to support the weight of the packing.

In one embodiment, as shown in fig. 8, when there are a plurality of branched gas pipes 232, the plurality of branched gas pipes 232 may be grouped in pairs and uniformly distributed on the opposite side walls of the main gas pipe 231, so that the branched gas pipes 232 can smoothly release gas and reduce the gas lift resistance.
Specifically, as shown in fig. 8, the extending direction of the branched gas delivery pipe 232 may be perpendicular to the extending direction of the main gas delivery pipe 231 and parallel to the horizontal transverse direction X and the vertical transverse direction Y.
The inner diameter of the branched gas pipe 232 may be smaller than the inner diameter of the main gas pipe 231, and the aperture of the aeration holes 2311 and 2321 may be much smaller than the inner diameter of the branched gas pipe 232. Moreover, it can be understood that, according to the principle of aerodynamics, when air flows in the aeration pipe 23, since the aperture of the aeration hole 2321/2321 is far smaller than the inner diameter of the aeration pipe 23, when the air rushes to the aeration hole 2321/2321 from the air inlet hole 132 along the aeration pipe 23, the flow velocity of the air will increase, which will cause the air to be sprayed out from the aeration hole 2321/2321 on the pipe wall of the aeration pipe 23, and the aeration effect can be achieved.
