Method for controlling a wastewater biological treatment plant comprising the following steps: A. receiving a detection of a quality (210; 310; 410) of oxygenation of water to treat, the detection of the oxygenation quality (210; 310; 410) being based on at least one value indicative of concentration of at least one among ammonium ion (NH4+), nitrite ion (NO2-) and nitrate ion (NO3-) in the water to treat, B. receiving a detection of a concentration of oxygen (02) dissolved in the water to treat, D. controlling one or more electrical apparatuses (140) which control a power supply to one or more respective electric motors for driving respective pumps (150) configured to activate an air or oxygen supply in the water to treat so as to cause the detected oxygen concentration to tend to an oxygen concentration setpoint (200; 300; 400), the method being characterised in that it comprises, between step B and step D, the following step: C. dynamically generating the oxygen concentration setpoint (200; 300; 400) as a function of the detection of the oxygenation quality (210; 310; 410). |
