FIELD: technological processes.
SUBSTANCE: group of inventions relates to a device for generating microbubbles and to a system for purifying contaminated water with a device for generating microbubbles. Microbubble generating device 10 contains liquid inflow channel 11 into which pressurized fluid flows, discharge channel 12 that discharges generated microbubbles and the liquid, throat part 13 connecting liquid inflow channel 11 and discharge channel 12, and gas supply channel 14 supplying gas to liquid inflow channel 11 or throat part 13. Further, the cross-sectional area of throat part 13, through which the flow passes, is smaller than the cross-sectional area of liquid inflow channel 11 or discharge channel 12. Moreover, supply gas channel 14 has an outlet end, which opens in the direction of the liquid flow. Said system for purifying contaminated water contains microbubble generating device 10 and containers with contaminated water and for flotation of microbubbles.
EFFECT: generation of microbubbles from contaminated water and the possibility of injecting contaminated water directly into the microbubble generating device.
