Beschreibung
Zusammenfassung:	A supercritical water oxidation reactor (100), including: a housing (101) provided with at least a slurry inlet (1011), an oxidant inlet (1012) and a discharge port (1013), wherein a chamber for providing a reaction zone is formed inside the housing (101); a heating device (102) used to increase a temperature in the chamber; a spiral circulation pipe (103) arranged in the chamber and having an end connected to the slurry inlet (1011), wherein a slurry is introduced into the spiral circulation pipe (103) from the slurry inlet (1011), flows along a pipeline of the spiral circulation pipe (103), and flows out from another end of the spiral circulation pipe (103); and wherein after flowing out from the another end of the spiral circulation pipe (103), the slurry is mixed with an oxidant flowing into the chamber from the oxidant inlet (1012) and an oxidation reaction occurs. A method of treating a radioactive organic waste by using a supercritical water oxidation reactor, a protective device for a reaction apparatus and a reaction system, and a supercritical water oxidation system and a method of treating solid combustibles by using the supercritical water oxidation system are further provided.
