Abstract
Invenţia se referă la un procedeu de epurare combinată a apelor uzate policomponente.Procedeul, conform invenţiei, include tratarea electrochimică a apelor uzate cu electrozi de fier solubili şi condiţionarea nămolurilor formate prin tratarea lor magnetică, totodată suplimentar se adaugă la agitare particule dispersate de magnetit în cantitate de 0,05...0,1 g/lşi peroxid de hidrogen în raport molar cu fierul solubilizat electrochimic de (0,02…0,05):(0,4…0,5). Procesul se efectuează la pH=6,5...8,5 cu iradiere ultravioletă a suspensiei cu lungimea de undă de 180...253 nm, cu o intensitate de 15...20 J/cm2·min. Totodată în calitate de particule dispersate de magnetit se utilizează deşeuri mărunţite de scorie/zgură provenite de la producerea oţelului laminat în industria metalurgică sau nămol feritizat ca produs al procesului anterior de feritizare a nămolului.
