A supercritical water oxidation-based reactor, comprising an inner housing and an outer housing is disclosed. The inner housing is coaxially provided in the outer housing; the inner housing is dividedinto two parts, i.e., an upper cylinder and a lower cone; the cylinder comprises an imperforate pipe (1411) at the upper section and a straight porous pipe (1404) at the lower section, and the cone is a conical porous wall (1407); the outer housing comprises an upper connecting flange, a middle straight pressure bearing wall (1403), and a lower conical pressure bearing wall (1409); a first annular gap is formed among the cylinder part of the inner housing, the straight pressure bearing wall (1403), and the connecting flange; a second annular gap is formed between the conical porous wall (1407) and the conical pressure bearing wall (1409); a separator ring (1405) is provided between the first annular gap and the second annular gap; a high-temperature evaporated water injection pipe (1402)is provided at the upper p
