| abstract | [PROBLEMS] To provide a water treatment method excellent in efficiency of a Fenton reaction in water treatment using a Fenton reaction accompanied by a reduction reaction. A water treatment method comprising steps (i) to (iii). (I) Ferrous ions and hydrogen peroxide are added to wastewater that satisfies the following condition (A) to oxidize aldehydes and oxidizable pollutants in the wastewater so as to satisfy the following condition (B). A reaction step (ii) for obtaining a reaction solution by performing an oxidation treatment and a reduction treatment for reducing ferric ions to ferrous ions in the presence of an iron reduction catalyst. The pH of the reaction solution is 6.0 or more and 10.0. An insolubilization step (iii) suspension in which a suspension in which ferrous ions and ferric ions in the reaction are insolubilized to obtain a suspension in which ferrous compounds and ferric compounds are suspended is prepared as follows: The first separation process that separates sludge and treated water. <Reaction conditions> (A) The pH of the waste water is 1.0 or more and 4.0 or less. (B) 0.17 ≦ T 1 / (C A × C B ) ≦ 1.2 [Selection] Figure 1 |
