    Abstract: 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.

    Abstract translation: 该方法包括以下步骤:a)提供预定体积的水,其具有关于溶解氧的含量,pH和REDOX电势的预定特性; b)向所述水体积加入被放射性物质污染的预定量的油和溶剂,所述电荷对应于作为预定水体积的预定分数的一定体积的油和溶剂; c)所述电荷在预定温度和持续时间内经受微生物的作用; d)取出所得废水的至少一部分; e)将水与包含在这些流出物中的物质分开; f)从所述水分离的材料被回收或抽空; g)再生含有流出物中的物质的水,使其回收所述预定特性; h)再循环至少部分所述再生水; i)重复步骤a)的循环。
