Abstract
The invention relates to the technical field of wastewater treatment, in particular to a supercritical water oxidation reactor for treating high-solid-content organic wastes, which consists of an upright section and an inclined section, wherein the top of the upright section of the reactor is provided with an inlet, the bottom of the upright section of the reactor is provided with an outlet, and the inclined section of the reactor is arranged on the side surface of the upright section; one end of the inclined section is communicated with the vertical section, and the other end of the inclined section is provided with an outlet. Also discloses a supercritical water oxidation reaction system for treating the intrinsic organic waste by using the reactor. The invention ensures that the gas-solid separation is carried out after the reactants are fully degraded by arranging the inclined section of the reactor, thereby improving the quality of the recovered steam.
