Claim 4:
5. The system according to claim 4, wherein part of the hydrodynamic cavitation bubbles flows with the groundwater to a tail end of the negative pressure chamber (12), bubble puncturing needles (8) arranged at a water outlet at the tail end of the negative pressure chamber (12) are capable of puncturing the hydrodynamic cavitation bubbles which flow from the vortex water inlet columns (15) into the negative pressure chamber (12) and do not break by itself under a sudden pressure change; and
large rotating blades (20) for generating a large-size vortex are provided on an agitation rotating shaft (11) arranged coaxially with the vortex chamber (18) of each of the hydrodynamic cavitators (17) and the negative pressure chamber (12), the agitation rotating shaft (11) being connected to a vortex chamber base (13) arranged at the tail end of the vortex chamber (18) of each of the hydrodynamic cavitators (17) and to a negative pressure chamber base arranged at the tail end of the negative pressure chamber (12), respectively, in a manner capable of maintaining a position and height of each of the hydrodynamic cavitators (17); and small rotating blades (16) for generating small-size vortices are arranged at the front ends of the vortex water inlet columns (15) and connected to the vortex water inlet columns (15) by means of blade fixing rods (28).
