Pond bottom aeration system

Abstract

The invention belongs to the technical field of aquaculture, and especially relates to a pond bottom aeration system which comprises a monitoring system, a control system, an air supply system, an air transportation system and an air jet system which are connected with one another in sequence, wherein the air jet system is distributed at different water areas and water layers at the bottom of a pond; the control system is used for controlling the air supply system, the air transportation system and the air jet system to work according to the detection result of the monitoring system; and the air jet system is used for outputting air to the different water areas and water layers at the bottom of the pond. The pond bottom aeration system is capable of efficiently dissolving oxygen, comprehensively supplying oxygen and supplying oxygen in layers, is favorable in air transportation performance, is provided with a whole pipeline system which is free of air leakage and corrosion, is easy to clean, has the advantages of low cost and low energy consumption, and is capable of improving an oxygen dissolving effect, activating a water body and realizing ecological aquaculture while realizing the all-around or local three-dimensional air supply of the pond.

Description

technical field [0001] The invention belongs to the technical field of breeding, and in particular relates to an aeration and oxygenation system at the bottom of a pond. Background technique [0002] At present, ponds for aquaculture generally use impeller-type or waterwheel-type aerators to increase oxygen on the water surface. The impeller rotates to stir the water body, pressurizes the upper layer of water to the lower layer, and discharges the waste gas at the bottom of the pond while conveying fresh air. To achieve the purpose of increasing oxygen and improving water quality. However, this method of using the impeller to stir and increase oxygen can only improve the water quality environment around the aerator, and the oxygen content of the water surface far away from the aerator cannot be effectively improved, and the oxygen melting rate is also limited. At the same time, the rapidly rotating impeller is easy to Injure the fish body and cause direct economic loss. ...
