HAZARDOUS SUBSTANCE TREATMENT METHOD, ITS APPARATUS, AND WASTEWATER TREATMENT SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a hazardous substance treatment method by which hazardous substances such as dioxins and endocrine disrupting substances can be decomposed and removed at high reaction efficiency and high decomposition rate even if wastewater to be treated contains a high content of salts inhibiting the decomposition of the hazardous substances, an apparatus for the method, and a wastewater treatment system.;SOLUTION: This hazardous substance treatment apparatus is provided with a treatment tank 10 that is divided into a reaction tank 20 and a fresh water tank 30 by partition plates 12. The reaction tank 20 is provided with an ozone introduction means 24 for introducing ozone 1, an ultraviolet irradiation lamp 22 for emitting ultraviolet rays, a supply port 26 of the wastewater 2 to be treated, and a discharge port 28 of treated water 6. The fresh water tank 30 is provided with a supply port 36 of fresh water 3 and a discharge port 38 of sewage 7. A selective membrane which prevents the passage of particles having a particle diameter of more than 1 μm is used for each partition plate 12.;COPYRIGHT: (C)2003,JPO
