Design principle of pond aerator

The aerator will surely have a certain understanding of it through the previous introduction, then do you know the design principle of the aerator?
    
The purpose of using an aerator is to add dissolved oxygen to the body of water. This involves both the solubility and dissolution rate of oxygen. The former includes three factors: water temperature, water salinity and oxygen partial pressure; the latter includes three factors: the degree of unsaturation of dissolved oxygen, the contact area and mode of water-gas, and the movement of water.
    
A stable condition in which the water temperature and the salt content of the water are. Therefore, in order to achieve oxygenation to the water body, it is necessary to directly or indirectly change the oxygen partial pressure, the contact area and mode of the water-gas, and the movement state of the water. In response to this situation, the measures taken when designing the aerator are:
   
1. Stir the water body with mechanical parts to promote flow exchange and interface renewal;
   
2. Disperse the water into small droplets, spray the gas phase, and increase the water-gas contact area;
   
3. Inhale by a negative pressure to disperse the gas into microbubbles and press into the water.
