The invention relates to devices for disposal of waste in solid, liquid and gaseous state thereof, in particular, it relates to devices for providing waste disposal by plasma-chemical destruction. A technical effect obtained by this invention is implementation of a reactor providing destruction of both organic and inorganic substances of residential solid and/or liquid waste. The technical effect is obtained by a reactor provided in form of a closed cavity having an input orifice connected to a waste feed apparatus and an output orifice for outputting gaseous products of destruction. Inner surfaces of the cavity are made electrically conductive entirely or partially and an electrode is inserted into the reactor. The electrode is isolated from the conductive surfaces and connected to a source of high-voltage pulses, and size of a gap between the electrode and the conductive surfaces of the cavity provides formation of plasma streamers by corona discharge.

The present invention provides a method and apparatus for dewatering a biological solid material employing both microwave irradiation and solvent extraction. The method comprises microwave irradiation pretreatment, solvent extraction dewatering, solid-liquid separation, and solvent recovery. Through microwave irradiation of an aqueous biological solid material, gaps in the solid material are increased, and the biological material is fractured, thus releasing more bound water in the solid material. Subsequently, the microwave-irradiated biological solid material is brought into full contact with an organic solvent, allowing the solvent to absorb and extract moisture from the solid, thus removing moisture from the solid. The aqueous solvent is then subjected to evaporation under reduced pressure or gasification under reduced pressure in a separation apparatus so as to separate the moisture and the solvent. The solvent is then compressed, condensed and recovered for recycling. Also provided is a device for implementing the dewatering method.

The invention broadens a range of devices for treating waste, and has an enlarged area of formation of corona discharge streamers, avoiding a need for a source of high-voltage pulses. The technical effect is attained by a device for ionic-electronic destruction of waste. The device includes a waste feed unit, a source of electrically charged substance particles, a suction air fan, an output tube, and a reactor. The reactor is implemented as a closed cavity with an input opening connected to the waste feed unit, with an output opening for removing gaseous destruction products connected to the output tube, and with an additional input opening connected to an outlet of the source of electrically charged substance particles.

A plasma or ionic reactor or gasifier implements an ultra-high temperature ionic gasification process that can be used in an environmentally friendly manner to dispose of dried biosolids from, for example, wastewater treatment plants as well other waste feed stocks such as municipal solid waste (MSW) to produce, for example, renewable syngas that can be used to provide heat, power, renewable fuels, renewable hydrogen, and/or renewable chemical production. The systems described herein do so by generating electrical arcs across the interior of the gasifier reaction chamber creating a localized, controlled temperature in excess of 3000 C along with ionic gas or particles (plasma). This ultra-high temperature gasification zone and active ionic environment combine to very effectively and efficiently break down molecules into their constituent atoms, in a process called complete molecular dissociation. This ultra-high temperature ionic zone will also rapidly decompose impurities in the feed stock such as microplastics, PFAS (Per- and Polyfluorinated Substances), and other fluorocarbon materials.
