<p><P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for treating water, capable of attaining oxidative decomposition of an organic matter, oxidative decomposition of a difficult-to-resolve compound in wastewater, oxidization of ammoniac nitrogen and the like by improving the activity of useful bacillus. <P>SOLUTION: With the water treatment apparatus, a microorganism activity portion 58 supplies micro nano bubble water containing useful microorganism activated by coarse micro nano bubble and fine micro nano bubble to at least one of a contact adjustment tank 2 and a catalytic oxidation tank 9 through water piping 14 from a microorganism culture tank 27. The activated useful microorganism and coarse and fine micro nano bubbles can enhance the water treatment capacity of the water treatment portion 57 composed of the contact adjustment tank 2, the catalytic oxidation tank 9, a circulation pump tank 15 and a discharge pump vessel 20. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
