Piezoelectric catalytic degradation assembly for underground water circulation well

The utility model discloses a piezoelectric catalytic degradation component for an underground water circulation well, which comprises a circulation well pipe, a sealer and a piezoelectric material reaction net cage arranged below the underground water level, and the sealer is arranged in the middle of the circulation well pipe and divides the circulation well pipe into an upper circulation well and a lower circulation well. The piezoelectric material reaction net cage is arranged on the sealer, an upper screen section is arranged on the circulating well pipe corresponding to the upper circulating well, a lower screen section is arranged on the circulating well pipe corresponding to the lower circulating well, and water through holes are formed in the upper screen section and the lower screen section. According to the device, the piezoelectric material can be fully contacted with circulating water, so that organic pollutants in underground water can be efficiently degraded, and the defects of a traditional un
