Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Example

[0023] See also Figure 1-3 As shown, the present invention provides a technical solution for water circulation purification equipment for aquaculture: the equipment includes a circulation barrel 1, in which a multi-stage purification component is arranged. A top cover 12 is arranged on the top of the circulation barrel, and a circulation pump 21 is installed on the top cover. The input end of the circulation pump is connected to the water source of the aquaculture pond through a circulation water inlet pipe 22, and the output end is connected to the circulation barrel through a purification water outlet pipe 23. Multiple groups of columns 11 are arranged at the bottom corners of the circulation barrel to support the entire equipment.

[0024] In the circulation barrel 1, a filter frame 24 is first installed to remove large particles of impurities in the water. A porous filter cotton 25 is arranged below the filter frame to remove suspended matter and fine particles in the water. A biological filter material layer 26 is arranged below the porous filter cotton to purify the water quality by the biodegradation of microorganisms. An activated carbon adsorption layer 27 is arranged below the biological filter material layer to adsorb organic matter and odor in the water. A cone cover 28 is arranged at the bottom of the activated carbon adsorption layer, and an activated carbon separation net 29 is installed in the cone cover to support the activated carbon adsorption layer 27.

[0025] A transfer pump 3 is provided on the adjacent side of the circulation barrel 1, and a base 31 is provided at the bottom of the transfer pump. The input end of the transfer pump is connected to the circulation barrel through a water intake pipe 32, and is used to absorb purified water. A control valve 33 is installed on the water intake pipe, and the control valve is used to adjust the water intake. The output end of the transfer pump is connected to the multi-stage fine filter assembly through a water delivery pipe 34.

[0026] The multi-stage fine filter assembly includes a primary oxygenated fine filter cartridge 4 and a secondary oxygenated fine filter cartridge 5. A primary multi-way pipe seat 62 is installed on the primary oxygenated fine filter cartridge, and a primary water inlet pipe 61 is connected to the water inlet end of the primary multi-way pipe seat, and the primary water inlet pipe is connected to the water supply pipe. A primary drain pipe 621 and a primary overflow pipe 622 are provided on the primary multi-way pipe seat, and the primary drain pipe is connected to the primary water inlet pipe. A primary overflow pipe 622 is also provided on the primary multi-way pipe seat, and a secondary water inlet pipe 63 is provided at its tail end.

[0027] The tail end of the secondary water inlet pipe is connected to a secondary multi-way pipe seat 64, which is installed on the secondary oxygenated fine filter cartridge 5. The secondary multi-way pipe seat is provided with a secondary drain pipe 641 and a secondary overflow pipe 642, which are connected to the secondary water inlet pipe. The secondary multi-way pipe seat is also provided with a secondary overflow pipe 642, whose tail end is connected to a circulating water outlet pipe 65, and a solenoid valve 66 is installed on the circulating water outlet pipe.

[0028] The outer walls of the primary drainage pipe 621 and the secondary drainage pipe 641 are respectively provided with a primary biological filter membrane 66 and a secondary biological filter membrane 67. These biological filter membranes have good water permeability and microbial adhesion, and are used to filter tiny particles and organic matter in the water, effectively extending the service life of the filter membrane and improving the filtering efficiency.

[0029] A water quality detector 68 is installed on the top of the primary oxygenated fine filter cartridge 4 and the secondary oxygenated fine filter cartridge 5 for real-time water quality detection. An air pump 7 is installed on the outer wall for injecting air into the oxygenated fine filter cartridge to increase the dissolved oxygen content in the water, thereby improving the water environment.

[0030] Working method:

[0031] After the circulation pump 21 is started, water is drawn from the aquaculture pond and enters the circulation barrel 1 through the circulation water inlet pipe 22. The water first passes through the filter frame 24 to remove large particles of impurities, and then passes through the porous filter cotton 25 to remove suspended matter and fine particles. The water that has been initially filtered continues to flow through the biological filter material layer 26, where the microorganisms are biodegraded to further purify the water quality. The water treated by the biological filter material layer flows into the activated carbon adsorption layer 27, where the activated carbon adsorbs organic matter and odor in the water. The water treated by the activated carbon layer passes through the cone cover 28 and the activated carbon separation net 29, and then flows into the primary oxygenated fine filter cartridge 4. In the primary oxygenated fine filter cartridge, the water is further filtered through the primary biological filter membrane 66, and the air pump 7 injects air into the cartridge to increase the dissolved oxygen content in the water. The water treated by the primary oxygenated fine filter cartridge flows into the secondary oxygenated fine filter cartridge 5 and is finally filtered through the secondary biological filter membrane 67.

[0032] The water treated by the secondary oxygenated fine filter cartridge is discharged through the secondary drainage pipe 641. Through the control of the solenoid valve 66, part of the water can be circulated back to the aquaculture pond, and part of the water can be discharged outside the system.

[0033] The water quality is monitored in real time by a water quality detector 68 to ensure that the water quality meets the aquaculture requirements. If the water quality does not meet the standards, the water intake can be adjusted by a control valve 33, or the circulating water output can be controlled by a solenoid valve 66 to ensure stable water quality.

[0034] The water circulation purification equipment of the present invention can effectively remove impurities and harmful substances in an aquaculture pond, and at the same time increase the dissolved oxygen content in the water, thereby providing a good living environment for aquatic organisms.
