The present invention relates to a vertical floating wind propulsion system that is able to increase the concentration of dissolved oxygen in bodies of water while reducing the concentration of contaminating organic matter under the action of biofilms of anaerobic and aerobic microorganisms, which transform or consume said organic matter in their metabolic processes. The present invention consists of a wind propulsion system, a grooved floating buoy, a system of internal and external culture media, a duct, a sediment collecting base and an anchor. The wind propulsion system captures wind energy to generate rotational movement which is transferred by means of a shaft to a system of thruster propellers, which are arranged inside the duct. As the water rises by hydraulic displacement, organic sediments and microorganisms that can attach to the internal and external culture media are carried with it, forming biofilms. These communities of microorganisms consume excess organic matter in their metabolic processes, reducing the concentration thereof in water. Furthermore, the water that is displaced to the surface can be oxygenated in a more efficient way when it comes in contact with atmospheric oxygen. The system can be located in critical areas in bodies of water and is kept in situ by means of a concrete anchor. The system is designed as a device that neither consumes electricity nor generates polluting emissions as it is wind-powered.
