Claim 5:
6. A hydrodynamic cavitator, wherein the hydrodynamic cavitator (17) comprises a vortex chamber (18) for generating vortices and hydrodynamic cavitation bubbles, wherein, the vortex chamber (18) is provided with a plurality of vortex water inlet columns (15), and each of the vortex water inlet columns has a water passing aperture with an adjustable length and width, in such a manner that the groundwater with different flow conditions is capable of undergoing an adjustable hydrodynamic cavitation effect in the vortex chamber (18), such that the hydrodynamic cavitator (17) is capable of adjusting a bubbling pressure and a breaking pressure of the hydrodynamic cavitation bubbles based on each of the vortex water inlet columns (15) which has the water passing aperture with an adjustable length and width, to control a number of the hydrodynamic cavitation bubbles generated, and growth time and breaking timing thereof, wherein the hydrodynamic cavitator (17) is provided with a vortex chamber (18) and a negative pressure chamber (12) in a flow direction of groundwater such that the hydrodynamic cavitation bubbles generated in the vortex chamber (18) by contaminated groundwater are capable of collectively breaking in the negative pressure chamber (12) based on a sudden pressure change, energy from collapsing and bursting of the hydrodynamic cavitation bubbles being capable of activating a remediation agent to effectively degrade organic contaminants in the groundwater.
