FIELD: agriculture.
SUBSTANCE: invention relates to a method and device for oxygen enrichment of a fluid. A method and unit (100, 206, 222) are proposed for obtaining the oxygen-enriched fluid. In accordance with various versions a flow of pressurised fluid (102, 124) is provided. In the flow of pressurised fluid a flow (114, 122) is introduced to obtain a mixture (126) of fluid/oxygen. The mixture is passed through the Venturi nozzle (134, 136) as an assembly in the presence of a magnetic field generated by the adjacent magnet unit (152, 154). Then the mixture is directed from the Venturi nozzle as an assembly into the container (164) for separating gas from fluid, in which the fluid component of the mixture passes down (170) with the specified content of dissolved oxygen, and the gas component is directed upwards (176) for injecting into the flow of the pressurised fluid.
EFFECT: use of the invention enables to obtain the fluid containing dissolved oxygen.
