Embodiment 1
[0041] This embodiment shows a method for increasing oxygen in water supersaturated with dissolved oxygen. Such as figure 1 Shown, this water body supersaturated dissolved oxygen oxygenation method comprises the following steps:
[0042] Firstly, step S1 is executed, and the compressed air and the sewage sucked from the water area are fed into the dissolved air tank 400 respectively, so as to obtain supersaturated dissolved oxygen water.
[0043] Then step S2 is executed, transporting the supersaturated dissolved oxygen water to the micronano bubble generator 500 and releasing the oxygen carried in the supersaturated dissolved oxygen water into micronano bubbles through the micronano bubble generator 500 .
[0044] Finally, step S3 is executed, and the sewage carrying micro-nano bubbles is returned to the water area through a plurality of pushers 600 placed below the water surface.
[0045] This step S1 also includes the step of mixing the pure oxygen prepared by using the o...
Embodiment 2
[0069] This example shows the second specific implementation of a method for increasing oxygen in supersaturated dissolved oxygen in a water body according to the present invention.
[0070] The main difference between the present embodiment and the first embodiment is that in this embodiment, the step of passing the pure oxygen prepared by using the oxygen generator 300 into the dissolved gas tank 400 is omitted.
[0071] Specifically, in this embodiment, the air tank 200 directly passes the compressed air (impure oxygen) through the pipeline through the dissolved air tank 400 and with the purified water transported from the tap water pipeline to obtain supersaturated dissolved oxygen water. Under certain pressure conditions, supersaturated dissolved oxygen water is generated, and then transported to the micro-nano bubble generator 500 through pipelines to generate countless air bubbles with a diameter of 100 nanometers to 10 microns, and finally connected to the micro-nano b...
Embodiment 3
[0077] This example shows the third specific implementation of a method for increasing oxygen in supersaturated dissolved oxygen in a water body according to the present invention.
[0078] The main difference between this embodiment and Embodiment 1 and Embodiment 2 is that in this embodiment, in step S1, at least the compressed air and the sewage and Purified water from tap water pipes to produce supersaturated dissolved oxygen water. The air storage tank 200 feeds compressed air into the oxygen generator 300 at the same time, and feeds compressed air into the dissolved air tank 400 through the bypass pipe, thereby realizing the simultaneous feeding of pure oxygen oxygen and air into the dissolved gas tank 400 , to generate supersaturated dissolved oxygen water in the dissolved air tank 400. Finally, the micro-nano-scale air bubbles and oxygen bubbles are released into the water body through one or more pushers 600 connected to the micro-nano bubble generating device 500, t...
