PROCEDE ET DISPOSITIF POUR TRAITER DES HUILES ET SOLVANTS CONTAMINES PAR DES SUBSTANCES RADIOACTIVES

摘要

The process includes the following steps: a) a predetermined volume of water is provided which has predetermined characteristics as to the content of dissolved oxygen, pH and REDOX potential; b) to said water volume is added a predetermined charge of oils and solvents contaminated by radioactive substances, said charge corresponding to a volume of oils and solvents which is a predetermined fraction of the predetermined water volume; c) said charge is subjected to the action of micro-organisms at a predetermined temperature and duration; d) at least part of the effluent obtained is taken; e) the water is separated from the materials contained in such effluent; f) the materials separated from said water are recycled or evacuated; g) the water free of materials contained in the effluent is regenerated so that it recovers said predetermined characteristics; h) at least part of said regenerated water is recycled; i) the cycle from the step a) is repeated.
