Abstract

The invention falls within the domain of waste-water treatment. The system according to the invention consists of: an activation tank, in which the settling chamber (11) is formed by the partition (8) and the transverse partition (10); and a thickening chamber (14) formed by the two partitions (8 and 12). The thickening chamber is connected by means of the opening (15) with the recirculation channel (21), which is formed by the partition (12), the adjustable partition (7) and the aeration element (16). The system according to the invention works on the principle that the air flow in the recirculation channel (21) creates underpressure, thus drawing the sludge from the thickening chamber back into the biological process in the activation tank. The opening (15) can be closed with a sluice, the sluice can be used to separate the recirculation channel from the thickening chamber. Sludge in the thickening chamber is thickened in the same way as in traditional sedimentation tanks.
