The invention relates to a novel method for treating waste water discharged from a purification or sewage treatment plant for local waste water. The invention is characterized in that the amount of endocrinically active hormones and hormones dangerous to aquatic environments or hormone metabolites from the group of oestranes contained in the discharged water is reduced in the flow of the waste water leaving the waste-water purification or sewage plant by guiding the same in the form of a continuous fluid body through the field or radiation cone of a radiation source emitting at least one type of ionizing radiation from the group of gamma, x-ray and electron radiation. The invention also relates to a device for carrying out said method and to the use thereof in addition to said device.
L'invention concerne un nouveau procédé servant à traiter l'eau d'écoulement s'écoulant d'une station de purification ou d'épuration pour des eaux usées communales. Le procédé selon l'invention est caractérisé en ce que la teneur du courant d'eaux d'écoulement en hormones ou métabolites d'hormones à action endocrine, critique pour l'environnement aquatique, du groupe des estranes, est réduit dans le courant des eaux usées quittant la station de purification ou d'épuration, par conduite de ces eaux usées, sous forme d'un corps liquide continu, à travers le champ ou le cône de rayonnement d'au moins une source de rayonnement émettant un rayonnement ionisant du groupe rayons gamma, rayons X et rayons électroniques. L'invention concerne également un dispositif pour l'exécution de ce procédé, ainsi que l'utilisation de ce procédé et de ce dispositif.
