Title:
METHOD FOR TREATING RADIOACTIVE WASTE WATER
Document Type and Number:
WIPO Patent Application WO2004049352
Kind Code:
B1
Abstract:
The invention relates to a method for treating radioactive waste water and water loaded with solids. According to said method, the waste water from at least one collecting basin is supplied to a cross-flow filtration and to a partial-flow filtration mounted parallel to said cross-flow filtration, in a treatment stage, and optionally flows through an ion exchanger, part of the waste water, concentrated by the cross-flow filtration, being supplied to the partial-flow filtration. The aim of the invention is to enable an almost complete separation of unharmful substances and radionuclides. To this end, a first reactor is used as a collecting basin for the waste water, in which, in a first treatment stage, the volume of the waste water is reduced by either aerobic treatment or oxidation of organic constituents, and in a subsequent second treatment stage, the waste water is treated in the cross-flow filtration and in the partial-flow filtration in such a way that the filtrate/permeate extracted from the cross-flow filtration is either directly used or supplied to the or another reactor.
