In the present invention, disclosed is a mechanical ballast water treating apparatus which destroys microorganisms by passing seawater or fresh water, supplied as ballast water for a ship, between disks, which relatively rotate. According to the present invention, the mechanical ballast water treating apparatus includes: a tank which includes an inlet formed on an upper portion thereof, an outlet formed on a lower portion thereof, and an accommodating space formed therein; a fixated disk which is formed in the tank to fixate an outer side thereof on an inner side of the tank and includes a through-hole formed on the center; a rotary disk which is arranged in the tank to have an outer side thereof placed apart from the inner side of the tank and is arranged to be placed apart from the fixated disk in parallel with the fixated disk; a shaft which is joined with the center of the rotary disk and transmits rotation power to the rotary disk; and a rotation motor which is joined with the shaft and provides rotation force. The mechanical ballast water treating apparatus destroys microorganisms by mechanically pressing the microorganisms while making the ballast water for a ship flow between the fixated disk and the rotary disk.
