The treatment of water by a biological technique. The water to be treated circulates in the interior of the reactor, in the space (2) located above the partition (1). It is aerated and agitated by a diffuser (3); it enters the reactor by the opening (4) and leaves by the opening (5). A volume of confined water, poor in oxygen, occupies at the bottom of the reactor the space (6) located below the partition (1) and has across its thickness a layer supersaturated in oxygen (10) occupied by the microalgae and aerobic microorganisms; a region rich in oxygen (11) occupied by aerobic microorganisms; a region (12) poor in oxygen and occupied by anaerobic microorganisms; and an intermediate region (13) occupied by aerobic and anaerobic microorganisms. The invention is applicable particularly, in its closed circuit configuration, to aquaria and by means of either a closed circuit or an open circuit, to the treatment of water.
