摘要:
Process for the decontamination of decontaminants in waste waters, wherein the waste water stream to be treated pass sequentially through following process steps,waste water treatment with hydrogen peroxide (H.sub.2 O.sub.2), irradiating at the same time with UV light,treatment with a reducing agent such as sodium dithionite,precipitation of existing metal contaminants, optionally followed by a filtration and/or a treatment with a selective ion exchanger.
