Abstract

PURPOSE: To permit removal of BOD in waste water by pretreating the waste water in a catalytic oxidation tank and a pressure flotation separation tank prior to treating of the same in an active carbon packed electrolytic cell.
CONSTITUTION: The waste water treatment device is constituted of a catalytic oxidation tank 1, a pressure flotation separation tank 2, and an active carbon packed electrolytic cell 3. The tank 1 is of a double cylindrical shape, into which the foam of air is introduced from the bottom part of a cylindrical part 4. Packings for the purpose of formation of biological membranes are loaded in an outside circumferential part 5. The liquid can be circulated by the ascending foam of the part 4. The tank 2 is of a cylindrical shape, and a flocculating agent 8 and the pressurized water from an air dissolving tank 9 can be injected through an inlet 10 into a central inside circumferential part 7. A scraper 11 for recovering of froth is provided in the upper part of the floating part. The tank 3 is constituted of a flotation part 12 with a flow regulating cylinder, a scraper 14 for recovering froth and an electrolytic part 13 packed with a granular active carbon between the cathode and the anode. When the waste water is pretreated with such tanks 1, 2, the waste water is made lower in molecules on account of the property changes of org. materials and the org. materials are effectively oxidized and decomposed in the tank 3.
