Description

Technical Field

[0001] The invention relates to the field of nanobubbles, in particular to a nanobubble generating device. Background Art

[0002] Tiny bubbles can remain in the water for a long time, thus increasing the dissolved oxygen in the water. In addition, due to the presence of tiny bubbles, tiny organic suspended matter in the water (such as corroded dead leaves, algae, etc.) can float on the water surface. By removing these suspended matter, the purification and activation of the water body can be promoted. In particular, when the bubble diameter is less than 50 microns, the bubble interface will be negatively charged, and some free radicals with oxidizing ability will be attached due to the change of the water molecule structure on the bubble interface. These free radicals can react with organic phosphorus and amine nitrogen in the water to turn them into harmless substances, thus being able to disinfect and sterilize the water used for aquaculture.
