Abstract: A water treatment system and a ballast water treatment method. A ballast water treatment system according to an embodiment of the present invention comprises: a first ballast water supply pipe for receiving a supply of ballast water from a first sea chest positioned in a non-explosion-proof area of a ship; an electrolytic bath for electrolyzing the ballast water supplied from the first ballast water supply pipe; a second ballast water supply pipe for receiving a supply of ballast water from a second sea chest, which is positioned in an explosion-proof area of the ship, and supplying the ballast water to a ballast tank of the ship; a filter provided to the second ballast water supply pipe so as to filter the ballast water passing through the second ballast water supply pipe; and a third ballast water supply pipe connected to the second ballast water supply pipe so as to supply the ballast water, which has been electrolyzed from the electrolytic bath, to the ballast water which has passed through the filter.

Abstract: A simultaneous interpretation system includes headsets for inputting and outputting voice, and a portable terminal for receiving an original language voice speech signal to be interpreted that is output from the first headset. The portable terminal outputs an interpreted voice speech signal based on the original language voice speech signal that has been interpreted into a different language to the second headset. The portable terminal either performs the interpretation or accesses an interpretation server to provide the second headset with the interpreted voice speech signal. Hence, the simultaneous interpretation is carried out using the short-range communication between the users by medium of the single portable terminal and thus more efficient and unrestricted conversation is realized.
