1. An ultrasound-electrode-nano-porous membrane coupling hydrogen production and sterilization system, comprising a vessel and a plurality of hydrogen production units arranged in the vessel, wherein a hydrogen production unit comprises a cavity, and a broadband ultrasonic generator and a circular hydrogen production electrode located in the cavity, the circular hydrogen production electrode wrapping around the broadband ultrasonic generator; a bottom membrane at a bottom of the cavity is hydrophobic at an inner side and hydrophilic at an outer side, and a side membrane of the cavity is hydrophilic at the inner side and hydrophobic at the outer side and is mounted vertically or obliquely upwards at an angle of 0-45 degrees from a vertical direction; and a top cover is made of an airtight material.
