<p><P>PROBLEM TO BE SOLVED: To provide a method of decoloring livestock wastewater and colored wastewater by the use of a persulfate and a metal oxidation catalyst. <P>SOLUTION: The method comprises filtering, in a filtering vessel 1, wastewater from livestock and/or colored wastewater fed from a wastewater storage tank 13, dissolving a persulfate in a chemical mixing vessel 2, making the wastewater pass through a purification vessel 3 to a catalyst vessel 4 where sulfate radical is generated to decompose colored ingredients through oxidation, introducing the wastewater into a final storage vessel 5 and adding sodium chloride to generate hypochlorite with the sulfate radical to decompose colored ingredients intensively. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
