<p>The invention concerns a method characterised in that it consists in: measuring the oxidoreduction potential on each tank; respectively transmitting said measurements to a data processing system to analyse the oxidoreduction potential evolution and establishing a diagnosis of the aeration/biology couple to ensure the degradation reactions of the carbonaceous and nitrogenous pollution and determining, on the basis of said diagnosis, whether to start, to continue or to stop the aeration on the tanks, depending on the required degree of purification such that, in the first tanks, priority is given to the treatment of carbonaceous pollution with specific parameter representation of the oxidoreduction potential threshold values and, in the last tanks fine-tuning the treatment of the carbonaceous and nitrogenous pollution by managing the aeration consisting in establishing the oxidoreduction potential evolution curve, measured on these tanks, based on time and in computing the differential coefficient, and when the latter approaches zero, correlating the differential coefficient and the oxidoreduction potential value to determine whether to start, continue or stop aeration on said tanks.</p> |
