Abstract of corresponding document: WO9418130
Biological activation waste water purification, wherein the waste water is biologically purified in an activation process, in course of which a nitrification occurred. The activation mixture is brought in the circulation circuit with a plug flow character, while the purified water is taken away from the said circuit and the activation mixture is mixed with the waste water after the purified water was taken away, hereby an oxygen lack at the surface of the particles of the activated sludge is caused bringing denitrification processes about. Resulting mixture is aerated which keeps the activated sludge in suspension and during the plug flow causes a gradual oxygen saturation. The apparatus comprises always two separation spaces (4) arranged adjacent to each other by their longitudinal sides, in which communication connections with the activation space are formed and the longitudinal distribution channel (5) formed between the said longitudinal walls is completely closed by an end wall at one side while at the opposite side a passage is arranged, by means of which it is connected with a system of flow channels (9, 7).
