The invention discloses a ship ballast water management system and method based on low-temperature plasma technology, comprising a filter, a low-temperature plasma inactivation device, a water pump, an instrument, a valve, a pipeline and the like; The 40um self-cleaning filter can completely intercept the solid particles and marine microorganisms with a body length greater than 40um in the ballast water. Through the self-cleaning function of the filter, the filtered sediment can be discharged to the local sea area with backwashing. The filtered ballast water is then processed by a low-temperature plasma inactivation device. The low-temperature plasma inactivation device includes a shell, a cathode, an anode and a DC narrow pulse driving power supply. Inactivation of seawater can completely eliminate the possibility of microorganisms in seawater surviving and growing in ballast tanks, and can ensure that the inactivation rate of life in ballast water is 100%. |
