Provided are an apparatus for removing phosphorous from wastewater including: a first coagulation sedimentation unit including a first rapid mixing tank, a first flocculation tank and a first sedimentation tank; and a second coagulation sedimentation unit including a second rapid mixing tank, a second flocculation tank and a second sedimentation tank, and a method for removing phosphorous using the same. The first rapid mixing tank stirs wastewater and an inorganic coagulant with low basicity at high speed and the second rapid mixing tank stirs the treated water supplied from the first sedimentation tank and an inorganic coagulant with high basicity at high speed. As a result, removal of phosphorous from the wastewater is maximized and coagulation and sedimentation may be optimized through control of metal content in the inorganic coagulants added to the first rapid mixing tank and the second rapid mixing tank.
