Claim 6:
7. The hydrodynamic cavitator according to claim 6, wherein each of the vortex water inlet columns (15) for generating the hydrodynamic cavitation bubbles is provided with water passing aperture for groundwater to pass through, and the water passing aperture is capable of changing a flow velocity of groundwater in the water passing aperture based on adjusting a cross-sectional size of the water passing aperture, to form the bubbling pressure adapted to flow conditions of groundwater at a current remediation stage or point; and the water passing aperture is capable of controlling growth time of the hydrodynamic cavitation bubbles based on changing a flow distance of the hydrodynamic cavitation bubbles in the water passing aperture, to adjust the breaking pressure to be adapted to the flow conditions of groundwater at the current remediation stage or point.
