Method of working-up incineration residues into a disposable material using an oxidizing wash treatment

摘要: Converting waste residues containing metallic components more reactive than Fe into a disposable material comprises: subjecting dispersed in scrubbing liquid to oxidation convert higher state; adding oxidant suspension formed during scrubbing; measuring redox potential of liquid; and controlling dosing depending on measured value. Preferred Features: Residues aluminum are scrubbed. Scrubbing is carried out at pH 3-5 or 7-12. The added the before out.
