[0024] This embodiment provides an aeration in-situ treatment device for aquaculture, which can not only increase the effective dissolved oxygen rate in the water body and provide a good living environment for aquatic organisms, but also effectively degrade COD Mn and ammonia nitrogen and other pollutants, promoting the improvement of water quality.

[0025] See also Figures 1 to 4 The aeration in-situ treatment device of this embodiment includes a shell 1, a chord window 2 is arranged on the side of the shell 1, an aeration in-situ treatment unit 8 is arranged inside the shell 1, a top cover 7 is installed on the upper end of the shell 1, and a through groove 9 is opened on the upper end of the top cover 7.

[0026] The aeration in-situ treatment unit 8 includes a microporous aeration pipe 82 , a biofilm hanging sheet 83 , a main frame 84 , an air pump 87 , a main flow pipe 88 and a branch pipe 89 .

[0027] A main frame 84 is provided inside the shell 1, and a plurality of suspended biofilm hangers 83 are provided inside the main frame 84. An air pump 87 is installed on a through groove 9, which is a circular hole opened at the upper end of the top cover 7. A main flow pipe 88 is provided at the lower end of the air pump 87, and a branch pipe 89 is provided at the lower end of the main flow pipe 88. A microporous aeration pipe 82 is installed at the lower end of the branch pipe 89, and a plurality of aeration holes 81 are opened on the microporous aeration pipe 82.

[0028] More specifically, the aeration in-situ treatment unit 8 further includes a support plate 85 and a support frame 86. The support plate 85 is mounted on the upper end of the main frame 84, the support frame 86 is mounted on the upper end of the support plate 85, and the connection between the main flow pipe 88 and the branch pipe 89 is located inside the support frame 86. The main flow pipe 88 and the branch pipe 89 at the lower end of the air pump 87 can be initially limited by the arrangement of the support plate 85 and the support frame 86, thereby improving the compactness of the overall device.

[0029] Preferably, a connecting column 3 is installed on the side of the other end of the housing 1, and a connecting blade 4 is arranged on the side of the connecting column 3. The arrangement of the connecting column 3 and the connecting blade 4 can improve the overall aesthetics of the device.

[0030] Preferably, a decorative tail wing 6 is installed on the side of the housing 1 near the connection blade 4, and a label paper 5 is arranged on the side of the decorative tail wing 6. By arranging the decorative tail wing 6 and the label paper 5, the overall aesthetics of the device can be further improved.

[0031] Preferably, the string window 2 is designed to be openable and closable, and one end of the string window 2 is adsorbed on the side of the shell 1 by a strong magnet, so that the string window 2 is easy to open and close.

[0032] It should be noted that the microorganism diffusion tube 10 includes a steel tube 101 and attapulgite balls 102. The attapulgite balls are arranged inside the steel tube as immobilized microorganism particles, and the steel tube is provided with a plurality of through holes as diffusion holes 103.

Mn and ammonia nitrogen and other pollutants, promoting the good effect of improving water quality.

[0034] It should be noted that the attapulgite ball 102 is a highly efficient microbial immobilization carrier, and its porous structure provides a large surface area, which is conducive to the adsorption and growth of microorganisms. By evenly spraying the mixed bacterial liquid on the attapulgite ball 102, the microorganisms can be effectively fixed to keep them stable during the treatment process. This immobilization method not only improves the degradation efficiency of microorganisms, but also helps prevent the microorganisms from being washed away by water, thereby ensuring the long-term stability and efficiency of the treatment system.

[0035] In addition, the high density of microorganisms loaded on the immobilized particles also means that more pollutants can be treated in a smaller volume, thereby improving the compactness and economic benefits of the overall treatment device.

[0036] In this embodiment, the microporous aeration device and the biofilm hanging sheet are both configured as a replaceable structure, and after reaching the service life, there is no need to replace the entire device, and only the inner core needs to be replaced for continued use.

[0037] The working principle and use process of the aeration in-situ treatment device of this embodiment are as follows:

[0038] When using an aerated in-situ treatment device, it is coupled to a microporous aeration device. The aeration pipe of the microporous aeration device has a smaller diameter of holes, a smaller volume of output oxygen bubbles, a larger contact area with water, and a higher oxygen transfer efficiency than traditional aeration devices, which can effectively increase the effective dissolved oxygen rate in the water body. The airlift microporous aeration device transports air to the underwater microporous aeration pipe 82 through an air pump 87, a main flow pipe 88, and a branch pipe 89, effectively dispersing the air into fine bubbles and releasing them into the water body. Adequate oxygen supply promotes the continuous release and attachment of immobilized microorganisms using attapulgite balls 102 as carriers to the biofilm hanger 83, thereby increasing the number of purification microorganisms in the water body. These microorganisms can effectively degrade COD Mn As the microorganisms continue to multiply on the biofilm hanging sheet 83, they not only increase the diversity and richness of the microbial community in the water body, but also optimize the microbial structure of the water body, further improving the efficiency of water purification.

[0039] The microporous aeration device is a device of the prior art, specifically, an aeration method that disperses compressed air into water through micropores. In this aeration method, the compressed air is dispersed through the micropores to form tiny bubbles, increasing the contact area between the bubbles and the water, thereby greatly improving the solubility of the gas in the water and effectively improving the oxygen transfer efficiency in the water.

[0040] The main innovative technical effects of the aeration in-situ treatment device of this embodiment are as follows:

[0041] 1) The air is transported to the underwater microporous aeration pipes through the air pump, the main flow pipe and the diversion pipe, effectively dispersing the air into small bubbles and releasing them into the water body; such a setting can improve the oxygen transfer efficiency, thereby increasing the effective dissolved oxygen rate in the water body and providing a good living environment for aquatic organisms;

[0042] 2) Biofilm hanging sheets can increase the number of purifying microorganisms in water bodies, which can effectively degrade COD Mn and ammonia nitrogen and other pollutants, thereby promoting the improvement of water quality;

[0043] 3) Using attapulgite balls as efficient microbial immobilization carriers, the porous structure provides a large surface area, which is conducive to the adsorption and growth of microorganisms, improves the degradation efficiency of microorganisms, helps prevent microorganisms from being washed away by water, and ensures the long-term stability and efficiency of the treatment system;

[0044] 4) The submarine model shell is designed on the exterior, which can be harmoniously integrated into the overall decoration of the fish tank;

[0045] 5) A replacement design for the microporous aeration device and the biofilm hanging piece has been added. When the service life is reached, there is no need to replace the entire device, only the inner core needs to be replaced for continued use.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
