The present invention relates to a micro-bubble generating device applied to wastewater to purify the wastewater by generating micro-bubbles and supplying oxygen. More specifically, the micro-bubble generating device comprises: a housing having an internal space formed therein, having a water inlet and an air inlet respectively formed in a side surface and a rear end thereof to feed water and air from the outside, and having an outlet formed in a front end thereof to discharge micro-bubbles generated when water and air fed through the water inlet and the air inlet colloid each other to the outside; and a nozzle unit seated on the inside of the housing, having a hollow groove inwardly formed on a front surface of a portion on which the outlet of the housing is formed, and having a plurality of flow pipes for feeding water fed through the water inlet and a plurality of air pipes for feeding air fed through the air inlet, wherein the flow pipes and the air pipes are respectively formed on a side surface of the hollow groove to be spaced apart at regular intervals in a circumferential direction of the hollow groove. A micro-bubble generating device according to the present invention has a simple structure, so the micro-bubble generating device may be easily produced in a small size and may be used anywhere. |
