Abstract:
A device for purifying a pollutants containing water by oxidation of said pollutants to form oxidation products and removal of said oxidation products, said device comprising:a) at least one reactor, said reactor comprising:a vessel;at least one inlet means for introducing the pollutants containing water to be purified in the vessel;at least one outlet means for the recovering of the purified water from the vessel;at least one duct centrally extending within the vessel, said duct being made of a material transparent to UV light;a UV lamp mounted within said least one duct, said UV lamp generating UV irradiation;an anode extending close to said at least one duct; anda porous medium surrounding the anode;a cathode extending behind the porous medium;b) a power supply operatively connected to said anode and cathode for generating between them a difference of potential; andc) means for removing the oxidation products form the water,whereby, in use, oxygen is produced by electrolysis at the anode and is converted in situ into ozone by the UV irradiation generated by the UV lamp, the so generated ozone reacting on the pollutants contained in the water and converting them into oxidation product while, in the meantime, cationic ions of heavy metals, Ca++ and Mg++ are attracted by the cathode.
