WATER TREATMENT METHOD USING A BIOLOGICAL REACTOR IN WHICH THE VELOCITY OF AIR CONTINUOUSLY INJECTED INTO THE REACTOR IS REGULATED, AND CORRESPONDING DEVICE

摘要

The invention relates to a method for treating waters with the aid of a biological reactor for fighting against nitrogenous pollution which is called input load and contained in said waters, wherein the reactor comprises a biomass ventilate by injected air. The inventive method involves at least one injected air speed adjustment stage and consists in continuously measuring said input N-NH4(CvEDD) load contained in the waters, wherein said measured input load is in particularly weighted by a time offset in such a way that the time-dependent speed control of the injectable air is derived.
