Reactor and reaction system based on supercritcal water oxidation, and phenolic wastewater treatment method
The present invention relates to the technical field of wastewater treatment. In the present invention, the reactor is provided with a double-shell reactor, a coaxial nozzle, an inner shell structure, evaporated water injection pipes and the like, so it is assured that the wastewater is inject into the reactor at a room temperature and is degraded thoroughly; moreover, with the evaporated water, the corrosion, salt deposition and local overheating in the reactor are prevented, so that the reaction process is guaranteed to be stable and reliable. and through a fuel system, a hydrothermal flame is formed in the reactor, so that the concentrated waste liquid injected into the reactor at the room temperature can be preheated to a supercritical reaction temperature, and the waste liquid is prevented from coking, scaling and the like in a preheating stage.
