[0032] like Figures 1-6As shown, the principle of the nano bubble generating device for water treatment provided by this embodiment is as follows: when using the device, according to the amount of water source or the range of water body to be treated, a number of bubbling ceramic microporous wheels 6 can be taken, and a sealing installation gasket 29 can be embedded and installed between two corresponding bubbling ceramic microporous wheels 6. Then, the two corresponding bubbling ceramic microporous wheels 6 with the sealing installation gasket 29 installed are connected together by a connecting ring buckle 7.

[0033] When the device is in operation, the underwater driving motor 1 drives the increase / decrease nano-bubble rotor 4 to rotate rapidly, and at the same time the submersible Roots blower 5 starts to work to draw outside air into the working chamber, and then quickly compresses the gas drawn into the working chamber of the submersible Roots blower 5, and quickly rushes the compressed gas into the increase / decrease nano-bubble rotor 4. The compressed gas entering the increase / decrease nano-bubble rotor 4 will rotate rapidly and fill the inner cavity of each bubbling ceramic microporous wheel 6. Because the increase / decrease nano-bubble rotor 4 is always in a rotating state, the submersible Roots blower 5 continues to rush compressed gas into the increase / decrease nano-bubble rotor 4, so that the high-pressure gas is instantly thrown out from the inner cavity of each bubbling ceramic microporous wheel 6 to release the pressure, forming a large number of nano bubbles around the increase / decrease nano-bubble rotor 4 and releasing them into the water body to be treated.
