The utility model discloses a wastewater oxygenation device with micro-nano bubbles. Comprising a high-pressure dissolved air tank (9), an air inlet pipeline (11), a water inlet pipeline (12) and a water outlet pipeline (13), and a hollow fiber membrane component (7) is mounted in the high-pressure dissolved air tank (9). According to the device, high-concentration dissolved oxygen water with the dissolved oxygen concentration of 50 mg/L-60 mg/L can be prepared, the dissolved oxygen concentration can still reach 30 mg/L or above after preparation is conducted for 3 h, and the dissolved oxygen concentration can still reach 20 mg/L or above after the dissolved oxygen water is stored for seven days at the normal temperature and the normal pressure in a sealed bottle opening; the dissolved oxygen water prepared by the device has high dissolved oxygen concentration and excellent stability, can be used as a novel oxygenation mode, and has a wide application prospect in the field of water treatment. 本实用新型公开了一种微纳米气泡的
