  • Groundwater circulation well system with pressure-adjustable hydrodynamic cavitation
    Patent number: 11912595
    Abstract: The present invention relates to a groundwater circulation well system with pressure-adjustable hydrodynamic cavitation, including a circulation well body, a sucked and injected water circulation assembly and a hydrodynamic cavitator. The sucked and injected water circulation assembly is based on a water suction and injection pump. The hydrodynamic cavitator is provided, inside a vortex chamber, with a vortex water inlet column capable of changing a water passing aperture. The hydrodynamic cavitator is capable of changing a bubbling pressure and a breaking pressure of hydrodynamic cavitation bubbles in the vortex water inlet column. The hydrodynamic cavitator generates vortices in the circulation well body to accelerate uniform mixing of a remediation agent and the groundwater. Energy from collapsing and bursting of the hydrodynamic cavitation bubbles activates the remediation agent such that contaminants in the groundwater are efficiently degraded.
