1. A device for purifying waste water or ground water, which is contaminated by organic substances that are biodegradable and that can be separated by adsorption/desorption, is described, which is characterized by a) a fermentation system used for biodegradation b) an absorber system that is equipped with a regenerative polymer adsorbent that is upstream or downstream from the latter, which is equipped with a feed pipe and a discharge pipe as well as with a steam feed and a drainpipe for the desorbate and the purified water, respectively, as well as c) a return pipe that connects the output of the downstream system to the input of the upstream system.

L'invention concerne un système d'épuration d'eaux usées ou d'eaux souterraines, contaminées par des substances organiques biodégradables pouvant être séparées par adsorption/désorption. Ce système se caractérise en ce qu'il comprend: a) un système de fermentation servant à la biodégradation, b) un système absorbeur pourvu d'un adsorbant polymère régénératif, qui est monté en amont ou en aval dudit système de fermentation et qui comporte une conduite d'amenée et une conduite de sortie, ainsi qu'une conduite d'alimentation en vapeur et une conduite de décharge pour le désorbat et une autre pour l'eau épurée, et c) une conduite de retour qui relie la sortie du système monté en aval à l'entrée du système monté en amont.
