The invention discloses a novel combined sedimentation tank, which comprises a water distribution ditch, a pre-sedimentation zone, a water distribution zone, a fine sedimentation zone and a water discharging ditch. The pre-sedimentation zone is internally equipped with an inclined plate settler and a sludge thickening cone. The fine sedimentation zone is equipped with an inclined tube settler, a sludge thickening cone, a floating sludge baffle and a floating sludge discharging hopper. The pre-sedimentation zone is used for sedimentation of large flocculent particles and the fine sedimentation zone is used for sedimentation of small flocculent particles. The distance between inclined plates of the inclined plate settler is larger the distance between inclined tubes of inclined tube settler. Through the floating sludge discharging hopper, floating sludge inside the floating sludge baffle is discharged outside the sedimentation tank at a fixed period. The novel combined sedimentation tank provides partition sedi
