Abstract
PURPOSE: To regenerate the deposited matter into agglutinant after high degree treatment of waste water, by neutralizing the organic waste water containing organic matter and chromatic components after coagulating, oxidizing and decomposing, and dissolving the deposited ferric hydroxide with mineral acid.
CONSTITUTION: In treatment of organic waste water containing organic matter and and chromatic components, such as waste water discharged from waste disposal plant, an agglutinant of which main content is ferric salt 17 is added, and pH is adjusted to 3W5.5, and the organic matter and chromatic components in the waste water are separated out together with flocs of ferric hydroxide 7. This treated water is oxidized and decomposed with iron salt 20 of oxidation catalyst and hydrogen peroxide 21 of oxidider. Then, alkali 18 is added to this oxidized treated water to set the pH 4 or more, and then the dissolved iron salt 20 is deposited as ferric hydroxide. This iron hydroxide is dissolved in a regeneration tank 8 by adding mineral acid, and is reused as ferric salt in the first coagulating separation process. Thus, the waste water may be treated at high degree, and the iron salt may be recycled.
