<p>A process for purifying wastewater including the step:a) rating the tanks and the aeration means on the basis of the lowest pollution load, referred to as the low load, which corresponds to the plant load during dry weather;b) running the plant during dry weather, or at low load, according to the nitrogen treatment method in a tank with biological dephosphatation;c) running the plant during wet weather, or at high load, by performing the physicochemical phosphorus treatment technique and the nitrogen treatment technique in two tanks, andd) controlling the plant by detecting the load situation it is in (high load or low load) and to adapt the operating configuration of the tanks to the actual load situation.</p> |
