Abstract: Disclosed are a filter cartridge and a water purification system. The filter cartridge includes a shell, a filter body and a central tube; the shell is provided with an accommodating chamber and a water inlet, a pure water outlet, and a wastewater outlet communicated with the accommodating chamber; the filter body is provided in the accommodating chamber, the water inlet is communicated with the wastewater outlet through the filter body, a water storage space is provided between an outer peripheral wall of the filter body and an inner wall of the shell, and the water storage space is communicated with the pure water outlet; and the central tube is provided in the filter body, a sidewall of the central tube is provided with a central hole communicated with the filter body, and a through hole at a lower end of the central tube is communicated with the water storage space.

Abstract: 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.
