In use of the bubble generating device, a pump body may be mounted to the first bubble generating body 11 of the primary bubble generating unit 1 and communicated with the first passage 111 of the first bubble generating body 11. One end of an air intake pipe is mounted to the air intake pipe mounting part 13 of the primary foaming unit 1 and communicated with the third passage 122 of the second foaming body 12, and the other end of the air intake pipe extends to a position above the water surface. The entire air bubble generating apparatus is immersed below the water surface. The pump body makes the water flow from the water inlet 102 of the primary foaming unit 1 to the foam outlet 104 through the foaming chamber 101, and the opening size of the end of the first channel 111 of the first foaming body 11 forming the water inlet 102 is smaller than the opening size of the other end of the first channel 111, so the self-structure of the first foaming body 11 makes the water flow form a high-speed water flow through the water inlet 102 of the primary foaming unit 1.

The third foam-making body 23 of the secondary foam-making unit 2 can be crushed by the third foam-making body 23 to form smaller-sized bubbles when being impacted by the third foam-making body 23 during the flow of a large amount of bubbles, and the smaller-sized bubbles can be discharged out of the secondary foam-making unit 2 from the respective bubble discharge passages 24. It will be appreciated that the direction of flow of the smaller sized bubbles exiting the secondary bubble generating unit 2 from each of the bubble exit passages 24 is altered. Then, the smaller-sized bubbles discharged from each of the bubble discharge channels 24 of the secondary bubble generating unit 2 further impinge on the inner wall of the fourth bubble generating body 31 of the tertiary bubble generating unit 3 to form smaller-sized micro-bubbles, and the flow direction of the micro-bubbles is changed to discharge the bubbles along the fifth channel 311 of the fourth bubble generating body 31. Because this bubble generating device is soaked below the water level, because of buoyancy, these micro-bubbles can come up from bottom to top to in the in-process that these micro-bubbles come up, on the one hand, micro-bubbles can take the pollutant in the aquatic of river course out of the water level from bottom to top and be favorable to the natural decomposition of pollutant, and on the other hand, micro-bubbles can accelerate the activity of the aquatic in the river course and further accelerate the decomposition of pollutant in the aquatic.

(1) when high-speed water flows from the water inlet 102 to the bubble outlet 104 of the primary bubble generating unit 1 through the bubble generating chamber 101, the bubble generating chamber 101 forms a negative pressure environment to allow gas to automatically enter the bubble generating chamber 101 through the gas inlet 103 of the primary bubble generating unit 1;
