Abstract

A method for treating waste water, comprising a step of providing waste water (Vr) to be treated, comprising at least one organic pollutant compound (C), and a step of addition of an alkaline reagent (Ra) to the waste water (Vr) to degrade the organic pollutant compound (C) and obtain alkalinized waste water (Va).Furthermore, the method comprises a maturation step of the alkalinized waste water (Va), in which the modified molecules (MM) coagulate to obtain mature waste water (Vm). The latter contains at least one flocculation (F) and ammonia (NH₃) and/or a precursor thereof.Furthermore, the method comprises a recovery step, in which at least part of the ammonia (NH₃) is removed from the mature waste water (Vm) and/or from a derivative thereof. Furthermore, at least a fraction of the recovered ammonia (NH₃) and/or a derivative thereof is reintroduced into the waste water (Vr) as an alkaline reagent (Ra).
