<p>The present invention provides a method and a device, by which it is possible to decompose and treat a large amount of organic halogen compounds, etc. which are environmental pollutants, to a low concentration range at which it is dischargeable as waste liquor to sewage in a short time, and it is also possible to decompose organic substances and nitrogen or phosphorus compounds which are hardly decomposable by oxidation. <??>To a sample solution 20 contained in a reaction vessel 10a in which an aqueous solution containing environmental pollutants is stored, for example, ultrasonic waves 50 are irradiated from a transducer 30a disposed at the central bottom portion of the reaction vessel 10a, and at the same time, ultraviolet rays are irradiated from an ultraviolet lamp 40a disposed at the peripheral edge of the reaction vessel 10a. In this instance, the ultraviolet lamp 40a is disposed at a position such that it does not interfere with the path of travel of ultrasonic waves 50. <IMAGE></p> |
