The selection of aeration equipment by the aerator manufacturer and the calculation of the efficiency of the aeration equipment are as follows: Cause and maintain reasonable water and air contact, and maintain a certain dissolved oxygen concentration in the water under the condition that the chemical action of microorganisms continues to consume CO2; Create sufficient mixing effect and circulating fluidity of water in the aeration area; Maintain a sufficient rate of liquid to make the microorganisms in the water float.
Aeration method and aeration equipment. Normally, the floating head is open, ignoring the high-yield effect of the high-pressure aeration fan in the fishing pond. Ensure that the freshwater fish in the water are not prone to lack of oxygen.
The general regularity of the vertical distribution of dissolved oxygen: During the afternoon and noon, there is a lot of dissolved oxygen in the surface water, and the contrast can reach more than 200%. The general trend is: as the water level increases, the dissolved oxygen content is greatly reduced. Generally speaking: the freely dissipated gas only accounts for the total oxygen consumption, and the oxygen consumption of the freshwater fishes only accounts for 5-15%. What is the changing trend of dissolved oxygen in water quality? The project contributes to the new rural planning.
After the night water quality is of course thermal convection, the dissolved oxygen is high in the upper wind in the morning, and the dissolved oxygen is low in the Prawn Pond Aerator lower part. High-pressure aeration fans for fishing ponds are currently widely used in aquatic product breeding. In our country, the critical oxygen value of freshwater fish in ponds is mostly between 1-2 mg/liter. The other 80-90% are inhaled by microorganisms and lost by the dissolution of organic compounds. Some farms said: ‘I have an aerator by the pond’, as if the aerator is.
