Abstract

POSTUPAK ZA NEUTRALISANJE TOKSIČNIH I ŠTETNIH OSTATAKA U PRAHU KOJI NASTAJU U PROCESIMA TOPLOTNOG UNIŠTAVANJA OTPADAKA u postrojenjima za regulisano sagorevanje i toplotno uništavanje otpadaka, imobilizacijom tih materijala unutar kristalne rešetke koju obrazuje hidraulično vezivo od aluminosilikatnih hidrata u toku vezivanja i otvrdnjavanja, naznačen time, što obuhvata obradu prašine rastvorom barijum hlorida, pri čemu se ostvaruje stehiometrijski odnos izmedju količine barijum hlorida i količine sulfata prisutnih u prašini, čime se rastvorljivi sulfati prisutni u toj prašini čine nerastvorljivim, dodavanje portland cementa otpornog na sulfate kao hidrauličnog veziva u dobijenu smešu, pri čemu maseni odnos prašine i veziva leži u granicama izmedju 1:1 i 5:1, mešanje dobijene smeše dok se ne dobije homogena cementna masa i livenje dobijene mase u kalupe, u kojima nastaje proces vezivanja hidrauličnog veziva da bi se na kraju dobilo tvrdo telo koje nakon negovanja ima mehanička svojstva i osobine nepropustljivosti jednake osobinama normalnog betona, i u kome je pomenuta prašina imobilisana i inertna, tako obradjena da ne može dospeti u okolnu sredinu. Prijava sadrži još 2 zavisna zahteva.
