PURPOSE: A disk filter for filtering sewage is provided to prevent a dead zone in which foreign matters are not removed during spraying of backwashing water, and to reduce a power ratio to prevent friction and load of a bearing. CONSTITUTION: A disk filter for filtering sewage includes the following: a plurality of disks(30) radially attached on a drum(20) supported by a bearing(10); a discharge pipe(60) discharging backwashing water to the outside; and a roller bearing supporting the bottom sides of the drum. The feed water transferred through an inflow pipe(40) is distributed to each disk. A slide bearing is installed at the bottom of roller-type bearings.
