The invention relates to the technical field of water treatment, in particular to a low-carbon reoxygenation rural sewage treatment system which comprises a first water inlet pipe, a water inlet tank, a first tank body, a second tank body, a third tank body and a first water outlet pipe. Water flow enters the first tank body, and microorganisms attached to the surfaces of fillers in the three filter layers of the first tank body are subjected to denitrification nitrogen removal in an anoxic environment; the filtered water flows into the middle part of the second tank body, and the fountain aeration device pumps out the filtered water gathered in the second tank body and sprays the filtered water to the tank surface of the third tank body, so that the oxygen content in the water in the third tank body is increased; bacteria and algae in the third pond body absorb carbon dioxide and release oxygen through photosynthesis, and the green and low-carbon effects are achieved; the treated water body flows out from a
