AI Technical Summary
Existing aerators have low dissolved oxygen efficiency because they promote water flow by causing gas to rise, resulting in insufficient water agitation and failing to effectively improve dissolved oxygen efficiency.
Design an aeration device that is installed at the bottom of the water body. It supplies oxygen to the water body through a pressurization component and increases the aeration area and stirring effect by using the stirring effect of the positioning pipe and the diversion pipe. The dissolved oxygen in the water body is increased by using a stirring and aeration method.
It effectively improves dissolved oxygen levels in water, prevents hypoxia stress in fish, enhances fish metabolism, optimizes water quality, and improves aquaculture efficiency.
