Title:
【発明の名称】水の電気分解によって発生するオゾンで水を処理する装置および方法
Document Type and Number:
Japanese Patent JP2003516229
Kind Code:
A
Abstract:
A process and a device for the treatment of water, especially for removing therefrom a large variety of pollutants, especially organic, inorganic and biological pollutants through in situ generation of ozone. Ozone is economically produced in situ at a high concentration through the interaction of electrolytically produced oxygen and UV light having a wavelength of 189 nm. The device has a set of anode and cathode for electrolytically producing nascent oxygen which reacts with UV light at a wavelength of 189 nm to produce ozone "in situ" within a vessel where the polluted water is submitted to the combinative action of ozone and other oxidation reactions. The device also has a hydrocyclone or retention tank of removing cationic pollutants such as heavy metals, free radicals as well as undesirable electrolysis byproducts such as nascent hydrogen through a secondary outlet. Oxidation by-products are subsequently removed from the exiting water stream by means of decantation, flocculation, coagulation or filtration.
