Abstract

PURPOSE: To make expensive ferric salt as an adsorbent unnecessary in treatment of org. waste water and to utilize industrial waste such as ferrous sulfate by recovering iron salt, as ferric hydroxide, used as catalyst in the treatment and by recycling the ferric hydroxide.
CONSTITUTION: Ferric hydroxide is added to biologically treated org. waste water to allow org. matter to be absorbed, and it is flocculation-separated together with suspended matter. To this treated water are added iron salt catalyst such as ferrous sulfate or ferrous chloride and hydrogen peroxide to oxidation-decompose the org. matter. An alkali such as slaked lime is further added to precipitation-separate the iron salt catalyst as ferric hydroxide sludge. Since the sludge recovered has been highly oxidized with H2O2 of high oxidation-reduction potential in the presence of catalyst, it contains no partially oxidized product of the org. matter and is harmless. So the sludge is reused as the adsorbent of the first process at pH≥3.
