Abstract
Invenţia se referă la un procedeu de regenerare a cărbunelui activ impurificat cu diverse substanţe anorganice şi organice în procesul de purificare a apei la staţiile de epurare a apei.Procedeul, conform invenţiei, include separarea impurităţilor mecanice, tratarea cu soluţie de KOH la pH 11…13 timp de 20…30 ore, spălarea cu apă demineralizată, uscarea la temperatura de 100…110°C timp de 3…5 ore şi tratarea termică la temperatura de 450…600°C în atmosferă de dioxid de carbon timp de 1,0…1,5 ore.Rezultatul constă în sporirea gradului de eliminare a substanţelor humice din porii cărbunelui activ uzat.
