摘要

the process is characterized by a controlled, continuous feeding of the vorbehandlungslos of a reprocessing plant uebernommenen, glasbildnern and a reducing agent having abfallfluessigkeit (a) in the middle of a in a melting pot of borosil ikatglasschmelze with a temperature in the range of 1000 degrees up to 1400 degrees c,(b) the conditions laid down in the formation of an "insular" drying and kalzinierzone (inselzone) at the schmelzenoberflache avoiding contact of the abfallfluessigkeit with tiegelwandung and the formation of a reducing atmosphere, and the widest possible avoidance of the environment r adiologisch and / or chemical ingredients in the exhaust time.the continuous feed allowed, under beruecksichtigung useful durchmessergroessen commercially erhaeltlicher crucible verhaeltnismaessig high durchsaetze suspensions from waste solution and glasbildnern, which otherwise only. in drehrohrschmelzoefen can be reached.a controlled feed means at the erfindungsgemaessen procedures that the waste solution according to their previously given solids content, with glasbildnern is mixed and without separation gleichmaessig and mischungsgleich in the crucible eindosiert.one of the many advantages of the erfindungsgemaessen procedure compared with the state of the art gehoerigen procedures is that the reprocessing...u.s.w
