The invention involves a folding patient transfer apparatus with a material top layer and a material bottom layer. A plurality of inserts has handhold openings that are formed in the inserts that are positioned between the material top layer and the material bottom layer utilizing a sewn plurality of insert seams. The seams form enclosed material chambers containing the inserts. The materials can be disposed of due to contamination; however the inserts can be sterilized reducing hospital waste and cost. The apparatus is configured to slide and / or lift and / or carry a patient from a non-planer surface to a second planer or non-planer surface.

A system for the sterilization of hospital waste, comprising a triturator that includes a hermetic cover, a hopper and toothed drums; an auger feeder to transport the triturated waste and comprising nozzles that blow steam into the waste; a high-temperature pressurized steam generator; an airtight sterilization chamber with microwave generators and with an inner stirrer, the sterilization chamber comprising a gate at the top, a gate on one side or in the front, and a stirring device for mixing the contents of the chamber. During the whole process the waste is completely insulated from the external environment. A central unit controls and supervises the operation of all the electric, electronic and mechanical parts of the system, which can be fit into a modular container for easy transportation.

An infectious waste treatment system uses a chlorine dioxide based liquid disinfectant generated from combining precursors comprising sodium chlorite, acid, and bleach. The waste is ground into small pieces and soaked in the liquid disinfectant. The chlorine dioxide is generated by combining dilute aqueous precursors with a flow of the liquid disinfectant into a circulation pump. A preferred set of precursors comprises an approximately 25 percent aqueous sodium chlorite solution, an approximately 12 percent to approximately 50 percent citric acid solution, and an approximately 12 percent industrial bleach (sodium hypochlorite) solution such as Clorox® bleach. A continuous gas monitoring system measures the concentration of chlorine dioxide in the liquid disinfectant and commands the chlorine dioxide generator to generate chlorine dioxide when necessary.

The invention relates to a hospital wastewater purification treatment system. The system comprises a grid, an adjusting disinfection tank, a coagulation pool, a primary precipitation pool, a hydrolysis acidification pool, an aerobic biological filter tank, a secondary precipitation pool, deep oxidation equipment, a sludge pool and a recycling water storage tank connected mutually; the grid is used for removing solid impurities; the adjusting disinfection tank is used for accumulating original wastewater discharged by various wastewater sources; the coagulation pool is used for adding and mixing a coagulant and a coagulant aid; the primary precipitation pool is used for precipitating precipitable substances of wastewater in the precipitation pool; the hydrolysis acidification pool is used for biodegradation in an anoxic state; the aerobic biological filter tank is used for converting organic molecules into inorganic molecules through biological action in an aerobic state; the secondary precipitation pool is used for precipitating newly generated water and original precipitable substances in the aerobic biological filter tank; and the deep oxidation equipment is used for oxidizing residual organic matters in the water which are different for biological treatment into inorganic molecules. The system has high purification degree; and outlet water can be used as recycled water for use.
