Abstract:
PROBLEM TO BE SOLVED: To provide a method for efficiently treating organic substance-containing wastewater using a simple apparatus with simple operation control, and to provide the apparatus for the method. SOLUTION: A reactor 1 has a double-pipe structure including an outer pipe 2, an inlet nozzle 3 disposed in the upstream lateral side of the outer pipe 2, an outlet nozzle 4 disposed in the lateral side of the outer pipe 2 downstream from the inlet nozzle 3, and an inner pipe 5 disposed inside the outer pipe 2. As the inner pipe 5, one having ozone permeability and oxidation resistance is used. The organic substance-containing water to which an ozone decomposition accelerator has been added is passed through the outer pipe 2, and an ozone-containing gas is supplied to the inner pipe 5. The ozone inside the inner pipe 5 permeates the inner pipe 5 to flow into the organic substance-containing water, and part of the ozone reacts with the ozone decomposition accelerator in the water to generate OH radicals. The ozone and the OH radicals decompose the organic substances in the water. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
An object of the present invention is to provide an ozone water having enhanced storage stability and a method for producing the ozone water. An ozone water of the present invention as a means for resolution is produced by dissolving 0.1 µM to 1 mM of an organic iron compound and 1 to 300 mM of an inorganic salt in a water with ozone-microbubbles generated using an ozone gas at a concentration of 1 to 300 g/Nm 3 . The half-life of ozone of the ozone water of the present invention is 3 days or longer, for example, when the water filled in an airtight container under atmospheric pressure is stored under a temperature condition of 40°C.
Abstract:
The disclosure relates to a method of performing ozonolysis or ozone-based oxidation on a liquid or emulsified reagent using a tubular falling film reactor with one or multiple tubes wherein the combined ozone and carrier gas flow is co-current.
Abstract:
The invention concerns a device (2) for treating a fluid comprising: - a pretreatment chamber (20) into which the fluid is likely to be discharged; - bubbling means disposed in the pretreatment chamber (20), designed to diffuse bubbles of a gas so as to oxygenate and/or oxidise the fluid; - a treatment chamber (26) communicating with the pretreatment chamber (20) and having a tilted bottom (28) allowing the flow of a film of fluid from the pretreatment chamber (20); and - radiation means (36, 38) designed to radiate ultraviolet rays, disposed over the bottom (28) of the treatment chamber (26), and arranged to extend at a distance from the film of fluid.
Abstract:
An apparatus for a programmable self sanitizing water dispenser apparatus with a digital controller as well as a programmable method for generating ozone for cleaning the reservoir and the water contained within it. The apparatus includes an anti-spill receiver that houses the controller and that can contain a ozone generator.
