The invention relates to a high-
magnetism vortex-type ultrafine bubble generation cavity and an aerator thereof, belonging to the technical field of
water treatment. The aerator comprises a high-
magnetism vortex-type ultrafine bubble generation cavity, a Venturi
pipe, a controller, an
oxygen gas source with a flow regulating valve, and a self-priming water pump, wherein the high-
magnetism vortex-type ultrafine bubble generation cavity, Venturi
pipe and controller are respectively electrically connected with the
oxygen gas source; the input end of the Venturi
pipe is respectively connected with the
oxygen gas source and the self-priming water pump; and the output end of the Venturi pipe is connected with the water inlet of the high-magnetism vortex-type ultrafine bubble generation cavity. The aerator has the characteristics of compact structure, small occupied area, low
energy consumption,
high oxygen utilization, low
cavitation corrosion, no blockage and the like, and can generate an N5
neodymium-iron-
boron high-magnetism material with the
magnetic field intensity of higher than 14500GS; and the volume of the output bubbles is lower than 10 mu m. The aerator is applicable to the field of in-
water aeration, can be used instead of the traditional dissolved gas tank, and is suitable for
sewage treatment, aquiculture and other
water body oxygenation aeration or floatation separation and other
water treatment techniques.
