Abstract

PURPOSE: To rationalize a waste water-disposal step with a saved resource consumption, by adding an oxidizing agent and a substance capable of dissociating ferric ion or the like in an oxidizing step to form oxidized sludge, and charging the oxidized sludge in a biological treatment step to form mixed sludge.
CONSTITUTION: Organic waste liquid 1, e.g. night soil or the like, is charged into a biological reaction vessel 2b in an active sludge process or the like, where the organic waste liquid is biologically treated to remove BOD and COD components and to nitrify and denitrify NH4-N. A slurry effluent 3 from the biological reaction vessel 2 is introduced into a sedimentation pool 4, where active sludge is separated, and overflowing water 7 is then introduced into a chemical oxidation vessel 8, where ferric sulfate 9 and hydrogen peroxide 10 are added to the overflowing water 7 to decompose the COD components and colorants. Slurry from the oxidation vessel 8 is neutralized in a neutralizing vessel 11, and oxidized sludge 13b is separated in a sedimentation pool 14. A mineral acid 24 is added to the mixed sludge 16b of the oxidized sludge 13b and the biologically treated sludge in an acidifying vessel 23 to form Fe3+ ion.
