PROCEDURE AND APPARATUS FOR THE PURIFICATION OF WASTE WATER BY BIOLOGICAL WAY.

摘要

ACCORDING TO THE INVENTION, IN WHICH THE WATER TO BE TREATED IS SHIPPED IN COUNTER-CURRENT WITH OXYGENATED GAS IN AN ASCENDANT REACTOR WITH FIXED-BED PARTICLES, IT IS USED AS A SUPPORT OF BACTERIA, DENSITY PARTICLES, BULK MATERIALS, INCLUDING K / 35 M3. THE BIOLOGICAL REACTORS OR FILTERS (1,1 '') IN SERIES INCLUDE: A THICKENING AREA OF SLUDGE (2); AT LEAST ONE OXYGENATED GAS INJECTION DEVICE (3.3 ''), ONE AREA OF FILTERING MATERIAL (4); A PARTICLE RETENTION COVER (7); A RESERVE AREA FOR WASHING WATER WITH EVACUATION (9) OF THE TREATED EFFLUENT. APPLICATION TO THE TREATMENT OF RESIDUAL WATERS AND WATERS TO POTABILIZE.
