Provided are a novel method and device for treating a liquid that are usable for treating ballast water used in a ship, etc. The liquid treatment method comprises: in supplying a liquid containing aquatic organisms, conducting an aquatic organism-inactivating treatment and/or a mechanical treatment using a centrifugal force, and storing the liquid in a storage means; and, in discharging the stored liquid, determining whether or not an aquatic organism-inactivating treatment is required, conducting the treatment on the basis of the determination result, and conducting a mechanical treatment using a centrifugal force. Due to this constitution, the liquid treatment method and device enable sufficient inactivation or separation of aquatic organisms that are contained in a liquid.
