The utility model relates to an integrated three-folded type three-dimensional cyclic oxidation ditch which comprises an oxidation ditch, a solid-liquid separator and an aeration rotary brush; a waterinlet is machined on the upper part of the oxidation ditch and the aeration rotary brush is mounted in front of the water inlet; the utility model is characterized in that the solid-liquid separatoris mounted on the lateral part of the oxidation ditch, two separator plates are arranged in the oxidation ditch to divide the oxidation ditch into three communicated cavities, including an upper layeraerobic zone, a middle layer anoxic zone and a lower layer anaerobic zone; the bottom of the solid-liquid separator is communicated with the lower layer anaerobic zone, the upper part of the solid-liquid separator is provided with a water outlet. Compared with oxidation ditch in prior art, the integrated three-folded type three-dimensional cyclic oxidation ditch has compact structure, simple construction, stable and reliab
