At present, the widespread use of fish pond aerators has reduced a lot of trouble, but people still do not understand the principle of fish pond aerators. First of all, we must understand its working principle, so that we can truly master its use. Next, introduce the aeration principle of the fish pond aerator.
As we all know, the purpose of using aerators is to increase dissolved oxygen in water, which includes the solubility and dissolution rate of oxygen. Solubility includes three factors: water temperature, water salt content and oxygen partial pressure. The dissolution rate includes three factors: the degree of unsaturation of dissolved oxygen, the contact area and method of water and gas, and the state of water movement. Among them, the water temperature and the salt content of the water are in a stable state of the water body and generally cannot be changed. The unsaturation of dissolved oxygen is a factor that needs to be changed, and it is also the current state of the water body. Therefore, in order to increase the production of oxygen in the water body, it is necessary to directly or indirectly change the partial pressure of oxygen, the contact area and method of water and gas, and the state of water movement. In this case, the measures taken when designing the aerator are as follows: 1) Use mechanical parts to agitate the water area to promote convection exchange and interface update. 2) Disperse the water into small droplets to spray weather, and the water vapor increases the contact area. 3) Disperse the gas into the microbubbles through negative pressure inhalation and push it into the water.
