PURPOSE: A precipitation tank for treating ballast water is provided to improve the efficiency of precipitation by suppressing turbulence or swirling in the precipitation tank due to a first or a second barrier. CONSTITUTION: A precipitation tank(100) for treating ballast water comprises: a tank body unit(110) in which seawater enters through a seawater inflow line of the tank body unit; the inner part of the tank body, divided into a first, second, and third precipitation tank by a first barrier(120); the first barrier having a first through hole(121), which is placed inside of the tank body perpendicular to the inflow of seawater and enables the first precipitation tank to be connected to the second precipitation tank; the second precipitation tank and the third precipitation tank, divided by a second barrier(130); the second barrier having a second through hole(131), which is placed inside of the tank body perpendicular to the first barrier and enables the second precipitation tank to be connected to the third precipitation tank; and a seawater exhaust line(140) on the third precipitation tank to drain precipitation treated seawater. |
