Abstract

Det beskrives en fremgangsmåte for behandling av avfall (D) ved tilsetning av en mengde av minst ett alkalisk reagens (R) som omfatter de trinn som består i å tilføre kontinuerlig avfallet som skal behandles, i en blander (1), tilsette konti- nuerlig til avfallet som skal behandles, en dosert mengde av minst ett alkalisk rea- gens, blande intimt og kontinuerlig i et gitt tidsrom avfallet og nevnte minst ene alkaliske reagens og, på samme tid, transportere den således oppnådde blanding gjennom blanderen, deretter tappe kontinuerlig denne blanding ut av blanderen, og det karakteristiske er at under blandetrinnet blir avfallet og et alkaliske reagens blandet suksessivt ved en første hastighet (V1), i en første oppholdstid (t1), og ved en annen hastighet (V2) som er lavere eller lik den første hastighet (V1), i en annen oppholdstid (t2) som ligger over tiden (t1).A process for treating waste (D) is described by adding an amount of at least one alkaline reagent (R) comprising the steps of continuously adding the waste to be treated in a mixer (1), adding continuously to the waste to be treated, a dosed amount of at least one alkaline reagent, intimately and continuously mixing for a given period of time, and the at least one alkaline reagent mentioned and, at the same time, transporting the mixture thus obtained through the mixer, then continuously draining it mixing out of the mixer, and the characteristic is that during the mixing step, the waste and an alkaline reagent are mixed successively at a first rate (V1), at a first residence time (t1), and at a second rate (V2) lower or equal to the first speed (V1), in a second dwell time (t2) over time (t1).
