The invention discloses a wastewater sedimentation reactor. The wastewater sedimentation reactor comprises a coagulating tank, a flocculation tank and a reaction tank which are arranged in sequence, wherein a sedimentation tank is arranged at a water outlet of the reaction tank; a first stirring device and a first feeding device are arranged in the coagulating tank; a second stirring device and a second feeding device are arranged in the flocculation tank; the second stirring device comprises a stirring motor electrically connected with a control device, a stirring shaft with a hollow structure, a spray head with a containing cavity and an oxygen generator; high-pressure oxygen is introduced into the waste water body of the flocculation tank so as to enable the high-pressure oxygen to be fully contacted and mixed with pollutants such as suspended solids and floc in the waste water body, the floc bridging, nucleation and sedimentation are facilitated, the floc sedimentation efficiency is improved, the floccula
