Abstract

Method and device for treating wastewater The invention relates to the field of wastewater or effluent treatment. According to the invention, a method for treating wastewater comprises: • a first step (A) of treating carbon contained in the wastewater (10) by 5 means of oxygen, • a second step (B) of treating the nitrogen contained in the treated water (14) at the end of the first step (A), • a third step (26) of determining a ratio (C/N) between a concentration of carbon and a concentration of nitrogen in the water (14) at the end of the 10 first step (A), • a fourth step (28) of controlling the supply of oxygen necessary for the first step (A) as a function of a difference between the determination carried out in the third step (26) and a strictly positive setpoint (30) of concentration ratio. 15 The invention also relates to a device implementing the method.
