Abstract: A kitchen waste wastewater treatment equipment includes a reaction kettle, a discharging mechanism and a pressurizing mechanism. In the process of high-temperature and high-pressure thermal hydrolysis of wastewater in the present disclosure, the pressurizing disk in the pressurizing mechanism continuously moves downwards in a vacuum state in the reaction kettle, reducing the volume in the reaction kettle and thus increasing the pressure. The secondary pressurization of wastewater is achieved while using heating for high-temperature and high-pressure, and the high-temperature and high-pressure environment greatly improves the reaction rate of thermal hydrolysis. The thermal hydrolysis reaction also generates gas for further pressurization, which greatly improves the treatment efficiency of wastewater. Moreover, the pressurizing mechanism and the exhaust annular groove can separate the gas generated after thermal hydrolysis.

Abstract: A material, and filters and other structures exposed to flowing gas that have the material therein, which removes VOCs, such as formaldehyde, from the gas. The material is a porous sorbent impregnated by a metal oxide, such as manganese oxide (MnOx) nano particles. The sorbent may be activated carbon, and the manganese oxide may catalyze formaldehyde to water and carbon dioxide while the carbon may adsorb formaldehyde, both mechanisms of which remove the VOC from the air to prevent or reduce inhalation of the same by humans. The material may be combined with an untreated sorbent or sorbent treated with ionic alkaline salts.

Abstract: The present invention provides a gas processing module, a gas processing method and a gas-phase organic compound processing method. A gas processing module comprises a cavity, a gas input unit, a light source, a photocatalyst, a liquid input unit, a gas discharge unit and a liquid discharge unit. The gas input unit is communicated with the inside of the cavity and used for supplying a to-be-processed gas comprising a gas-phase organic compound into the cavity. The light source is arranged in the cavity and used for providing a first light. The photocatalyst is arranged in the cavity, and at least a portion of the gas-phase organic compound of the to-be-processed gas which comes into contact with the photocatalyst generates an organic compound product under the action of the photocatalyst when irradiated by the first light. The liquid input unit is communicated with the inside of the cavity and used for providing a solvent to come into contact with the surface of the photocatalyst, and the organic compound product can be dissolved into the solvent.

Abstract: Processes and apparatuses converting poly- and perfluoroalkyl substances (PFAS). An oxidation reaction zone, preferably a thermal oxidizer, is utilized to oxidize the PFAS into anionic fluoride species. A treatment zone is utilized on at least a portion of the oxidation zone effluent before the oxidation zone effluent is vented or otherwise released to the atmosphere. The treatment zone may include a dry sorbent injection zone; a selective catalytic reduction zone, a wet scrubber zone; a carbon bed; an ion exchange zone; or any combination thereof.

Abstract: A multi-waste processing system includes a processing chamber. The processing chamber includes one or more heaters and a piston, and the processing chamber is configured to evaporate liquid waste and compact solid waste input. A condenser is operably connected to the processing chamber. The condenser is configured to condense water from the evaporated liquid waste output from the processing chamber. A gas and water separator is operably connected to the condenser. The gas and water separator is configured to separate water from the evaporated liquid waste output from the processing chamber. A recirculation pathway connects the gas and water separator to the processing chamber to recirculate gas from the gas and water separator to the processing chamber. The piston is actuated to keep the one or more heaters in close proximity to the solid waste and the liquid waste in the processing chamber.
