The invention relates to a combined Carroussel oxidation ditch. A ditch body consists of a left area, a middle area and a right area, which are parallel to one another, the left area comprises an anoxia pond and an anaerobic pond, which are arranged in a way of one above the other and share one pond wall I, the shared pond wall I is provided with a water flow channel, the middle area comprises a two-ditch annular oxidation ditch, the two-ditch annular oxidation ditch and the anoxia pond share a pond wall II which is provided with an upstream water flow channel, an area I between the anoxia pond and the two-ditch annular oxidation ditch forms a nitrification liquid refluxing pond, the anoxia pond and the nitrification liquid refluxing pond share a pond wall III which is provided with a wall-through pump which is used for pumping the nitrification liquid back to the anoxia pond, and a shared pond wall IV of the nitrification liquid refluxing pond and the two-ditch annular oxidation ditch is provided with a water flow channel; two settling pond and the carroussel oxidation ditch are integrated into a whole body, so that the floor occupation area is reduced, and the investment cost is reduced.
