The present application relates to the technical field of sterilization and disinfection, and provides a sterilization device. The sterilization device is provided in a pipe through which a media carrier flows, is connected to a direct current power supply, and comprises a media electrolysis module provided in the pipe through which the media carrier flows, and is configured to implement electrolysis or ionization of the media carrier to increase the ion concentration in the media carrier, a high voltage generation module configured to convert the low voltage direct current output by the direct current power supply into a high voltage direct current, and act on the electrolyzed or ionized media carrier, so that ions carry energy, and a feedback unit comprising a coil, the feedback unit being connected to the media electrolysis module and the high voltage generation module, being configured to detect a feedback voltage generated when an energy-bearing ion passes through the coil, and performing closed-loop control according to the feedback voltage, so as to adjust, in real-time, the electrolysis or ionization frequency of the media electrolysis module and the output voltage of the high voltage generation module. The present application improves the utilization rate of a media carrier and has a feedback adjustment function.La présente invention relève du domaine technique de la stérilisation et la désinfection, et concerne un dispositif de stérilisation.
