| 摘要 |
A method for electrochemical oxidation decomposition of difficult to decompose compounds like aromatic compounds, organic chlorine compounds, agricultural chemicals, dioxin, PCB and water soluble polymers that are contained in waste fluid, such as print developing waste fluid, factory waste water and industrial waste water of things such as landfill soil seeping waste water by carrying out electrolysis at a high current density to eliminate and purify difficult to decompose substances in the waste fluid. Waste fluid containing difficult to decompose substances is introduced into an electrolytic chamber with an anode that is a ferrite electrode, electrolysis is performed at a high current density of 10 A/dm2 or higher, hypohalogenous acid and active oxygen are generated in the waste fluid along with a strong anode oxidation action being brought about, and the oxidation decomposition is repeated by re-circulating the waste fluid through a filter, electrolyzer and intermediate collecting chamber.
