Abstract

POSTUPAK ZA PREČIŠĆAVANJE OTPADNE VODE KOJA SADRŽI NITRAT I/ILI NITRIT, naznačen time, što se postupak izvodi u dva stupnja, pri čemu se u prvom stupnju otpadna voda provodi pod redukujućim uslovima kroz bazen ili filter koji sadrži prirodni materijal, kao što je pesak, mešavina peska i makadama ili dolomit, u vremenskom periodu od 1-20 časova, najbolje 3-4, što, prema potrebi, voda povratno kruži u ulaz redukcionog suda, što se zatim tako redukovana voda oksiduje u drugom stupnju u oksigenatoru, zatim kruži u bazenu preko oksigenatora pri čemu se meri redoks potencijal dok se predje 200 MV pri pH od 7, i drži u bazenu dok se proces oksidovanja ne završi. Prijava sadrži još 2 zavisna zahteva.
