PROCESS AND APPARATUS FOR THE BIOLOGICAL PURIFICATION OF ORGANIC COMPOUNDS AND DERIVATIVES CONTAINING WATER BY THE DIFFUSION AND ACTIVITY OF AEROBIC AND ANAEROBIC MICROORGANISMS

摘要

The water to be treated circulates inside the reactor in the space (2) situated above the partition (1); it is aerated and stirred by a sparger (3); it enters the reactor through the orifice (4) and leaves it through the orifice (5); the volume of confined, oxygen-depleted water occupies, in the lower part of the reactor, the space (6) situated below the partition (1); it has, in its thickness, an oxygen-supersaturated layer (10) occupied by microalgae and aerobic microorganisms; an oxygen-rich zone (11) occupied by aerobic microorganisms; an oxygen-depleted zone (12) occupied by anaerobic microorganisms; and an intermediate zone (13) occupied by aerobic microorganisms and anaerobic microorganisms. …The invention applies especially, in a closed circuit, to aquariums and, in an open circuit or in a closed circuit, to water treatment. ……
