The present invention relates to a system for disposal of waste containing food waste or livestock manure and production of energy and a method therefor, wherein the system can dispose of waste, such as food waste or livestock manure, without using chemical additives or a precipitation bath generally used for disposal of wastewater, and can allow separation of wastewater and solid organic substances from the waste, disposal thereof, and then recycling thereof, respectively.

A salt separator separates salts and/or solid materials from a pumpable aqueous fluid mixture under process conditions, which lie in the range of the critical point for the fluid mixture. The salt separator contains a reaction zone in a cavity for transforming the pumpable aqueous fluid mixture into a raw mixture, e.g. a methanation reaction, and a feed opening for the pumpable aqueous fluid mixture to the cavity. The feed opening is realized in a rising pipe that protrudes into the cavity. A first extraction opening is provided for the raw mixture freed of salts and/or solid materials. The first extraction opening is arranged in the upper region of the cavity and a second extraction opening is provided for a brine containing the salt and/or the solid materials. The second extraction opening is arranged in the lower region of the cavity and is located lower down than the feed opening.

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.

Methods, systems, and apparatuses configured to separate waste solids material from a supercritical wastewater feed may separate waste solids material from supercritical reactor effluent in a first region such that the waste solids material collects in a second region fluidically interposed between a first valve in an open state and a second valve in a closed state, the first valve being fluidically interposed between the first region and the second region. In addition, the first and second valves may be toggled between open and closed states according to a defined duty cycle such that the waste solids material is caused, at least in part, to be discharged from the second region via the second valve in response to the first valve being in a closed state and the second valve being in an open state.

A near-zero-release treatment system and method for high concentrated organic wastewater is in the chemical engineering and environment protection field, whose core technology is SCWO. The wastewater and sludge are grinded by the homogeneous pump, pressurized by high-pressure plunger pump, transported to successive pipeline for preheating and mixing with the oxygen and undergoes SCWO reaction in the reactor. After pressure release in the pressure relief device, the reacted fluid passes through the self-cleaning filter and gas liquid separator for insoluble solid and gas separation; then enters the MVR for crystallization of the soluble salts to realize near-zero-release of the feeding. The regular water treatment technology (coagulation sedimentation, membrane biotechnology, membrane technology, etc.) is adopted to complement SCWO, which lowers the operating parameters of the reactor and cuts the operating cost by treating the remaining COD with regular water treatment technology.
