The invention discloses a supercritical water multi-pass resourceful treatment system for organic hazardous waste difficult to decompose

The utility model discloses a supercritical water multi-pass resourceful treatment system for organic hazardous waste difficult to decompose. The device comprises a waste pretreatment tempering device, a first-stage reactor, a second-stage reactor, a heat regenerator, a gas-liquid-solid three-phase separator and a liquid-solid separation device, and the first-stage reactor, the second-stage reactor, the heat regenerator, the gas-liquid-solid three-phase separator and the liquid-solid separation device are sequentially connected. On one hand, complete decomposition and resource utilization of organic hazardous waste can be realized by the system disclosed by the utility model; on the other hand, part of separated high-pressure water enters a reaction stage I to be rapidly mixed with organichazardous waste and heat the waste after being heated by a heat regenerator, and meanwhile, the other part of separated water is used for tempering and size mixing after being decompressed, so that the consumption and discha
