What is the function and principle of the aerator in the pond?

(1) use mechanical parts to stir water to promote convection exchange and interface renewal;

(2) Disperse water into small droplets and spray them into the gas phase to increase the contact area between water and gas.

(3) By negative pressure suction, the gas is dispersed into microbubbles and pressed into water.

According to these principles, various types of aerators have been designed and manufactured, and either measures to promote oxygen dissolution or two or more measures have been taken.

Extended data:

1. Application prospect of aerator;

China is a major fishery producer in the world, and its fishery output has been in the forefront of the world for 20 consecutive years. The gross domestic fishery value accounts for 10% of the total national agricultural value. China's aquaculture is gradually developing in the direction of high density and intensification, and the total output of aquaculture is increasing year by year, which is inseparable from the gradual realization of aquaculture mechanization, especially the wide use of aerators.

It can be said that the aerator is an essential basic equipment to realize fishery modernization in China.

2. The improvement of the aerator to the pond is mainly manifested in: when the fish pond is short of oxygen, the low-pressure aerator can be turned on to pay for fish and shrimp in advance. When the dissolved oxygen in the upper layer is high in sunny days, it can accelerate the convection of water, improve the dissolved oxygen in the middle and lower layers, help the rapid growth of fish and shrimp and reduce the feed coefficient.

Promote the oxidative decomposition of organic matter and reduce the occurrence of diseases. In addition, the circulation of water also promotes the reproduction and growth of plankton and improves the primary productivity of the pond.
