The invention relates to a supercritical water oxidizing reaction system for treating radioactive organic waste liquid. A reactor comprises an inner barrel and an outer barrel, wherein the inner barrel defines a reaction cavity; the outer barrel surrounds the inner barrel in a peripheral direction, and a cooling cavity is defined between the outer barrel and the inner barrel; cooling water flows in the cooling cavity to cool the inner barrel; and the reactor further comprises a spiral electric heating resistance wire which is mounted and fixed in the reaction cavity, a supercritical water oxidizing region is formed by an internal ring cavity region surrounded by the electric heating resistance wire, the reactor further comprises an inlet tube which extends into the supercritical water oxidizing region, a subcritical water region is formed by a non-supercritical water oxidizing region in the reaction cavity, and inorganic salt in a reaction product is dissolved again in the subcriticalwater region.
