As the water environment is increasingly polluted, wild fish resources continue to decrease, and the density of aquaculture continues to increase, traditional aerators can no longer meet the three-dimensional oxygenation needs of breeding ponds. High-efficiency green oxygen-enriched breeding is now popular internationally. This technology uses a pressure swing adsorption oxygen generator as a gas source to oxygenate the breeding water to reach a supersaturated dissolved oxygen level. At the same time, some other physical means are used to disinfect and purify the water body, and strictly control the water quality, thereby creating a good and healthy breeding water environment. The water environment is improved and there is sufficient oxygen in the water, which inhibits the growth of harmful anaerobic microorganisms. At the same time, the disease resistance of cultured aquatic organisms is improved and their vitality is strong, which shortens their breeding cycle, thereby reducing breeding costs and reducing breeding risks. The use of oxygen-enriched breeding will not only increase production, but also increase the sales price accordingly.
