Water body oxygen aeration technology and device thereof

Abstract

The invention discloses a water body oxygen aeration device which comprises an oxygen aeration tank. The water body oxygen aeration device is characterized in that the oxygen aeration tank is provided with a low-oxygen water body inlet, a high-oxygen water body outlet and an oxygen inlet. The low-oxygen water body inlet is connected to a culture pond through a water pump. The water pump pumps a water body in the culture pond into the oxygen aeration tank. The oxygen inlet is connected with a pure oxygen source. Oxygen enters the oxygen aeration tank from the oxygen inlet and is fully mixed with the water body pumped by the water pump in a high-pressure environment. A high-oxygen water body after being mixed with the oxygen is drained back into the culture pond from the high-oxygen water body outlet. According to the water body oxygen aeration technology and the device of the technology, under the circumstance of high pressure, the oxygen is dissolved into the water, the dissolved oxygen in the water is supersaturated and enters the culture pond through a pipeline, the purpose of increasing the dissolved oxygen is achieved, high-density culture can be achieved, the oxygen dissolving efficiency of the unit water body is promoted, the unit yield of the oxygen aeration water body is high, and the concentration of the saturated dissolved oxygen of the water is improved.

Description

technical field [0001] The invention relates to the technical field of water body oxygenation, in particular to a water body oxygenation technology and a device thereof. Background technique [0002] There are several methods of oxygenation in pond water, such as chemical oxygenation, biological oxygenation, and mechanical oxygenation. Chemical oxygenation is mainly to artificially put some chemical preparations into the aquaculture water body, which will chemically release oxygen in the water after meeting the water, thereby increasing the dissolved oxygen content in the water body; biological aeration refers to the breeding pond mouth ( Such as freshwater shrimp, river crab, fish, etc.) to plant appropriate amount of aquatic plants or artificially increase the amount of phytoplankton in the water body, through the photosynthesis of aquatic plants and phytoplankton, absorb carbon dioxide in the water body and release oxygen to achieve the purpose of water body oxygenation; ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved and the technical task proposed by the present invention are to improve the existing technology, provide a water body oxygenation technology and its device, and solve the problem that the water body oxygenation efficiency is low in the current technology, and the dissolved oxygen content is low and cannot reach saturation. state, low safety, easy to cause accidents, and easy to cause harm to fish, shrimp and crabs
