Description

technical field [0001] The invention relates to the technical field of oxygenation equipment, in particular to a pulsating oxygenation device for a floating seedbed. Background technique [0002] At present, in the floating seedbed breeding system, the water in the water bed is mostly static and has poor fluidity. The closely floating seedling tray on the surface of the water bed blocks the contact area between the water surface and the air, reduces the interaction area between water and air, and is affected by bacterial growth. , can easily lead to a decrease in dissolved oxygen in water. Low oxygen concentration and eutrophic water further accelerate the reproduction of facultative anaerobic and anaerobic bacteria, resulting in poor water quality, acidification and other problems, which ultimately affect the germination and growth of seedlings.

Low oxygen concentration and eutrophic water further accelerate the reproduction of facultative anaerobic and anaerobic bacteria, resulting in poor water quality, acidification and other problems, which ultimately affect the germination and growth of seedlings

[0003] The traditional methods of regional oxygenation and pump extracorporeal circulation have the following problems: first, the air bubbles are large, the specific surface area of ​​air-water contact is small, the water retention time is short, and the oxygenation effect is poor; second, the composition of water in the floating seedbed It is very complicated, and contains a lot of sand and stones and floating objects, which has a great erosion effect on the pump and poor system reliability; thirdly, both the circulating pump and the air pump need electric energy to drive, the system consumes a lot of energy, and the economic benefit is poor
