The utility model discloses a deep aeration equipment in integration oxidation ditch, including the integration oxidation ditch body, in a plurality of deep aerator and underwater propulsor, the integration oxidation ditch is internal to have set gradually anaerobism reaction tank, hypoxia response pond, aerobic reaction pond, sedimentation tank along the sewage flow direction, well deep aerator horizontal installation is apart from aerobic reaction pond 1.3~1.7 meters of bottom of the pool, well deep aerator passes through the aeration supply air duct and is connected with the aeration fan, underwater propulsor installs perpendicularly in the aerobic reaction pond, underwater propulsor's cable passes through the guide arm and is connected with the power. The utility model discloses sewage treatment in -process aeration time has been increased, more effectively flow state in the controlled reaction pond and mixed reaction state to can reduce the aeration by a wide margin and push away the energy consumption that flows, and very big convenience is provided to subsea equipment's maintenance and change to increase the service depth of water, reduced structures area.
