Analysis of the concentrations and fate of heavy metals and sewage in municipal sewage treatment systems

Creators

Description

The fate of selected substances during sewage treatment was investigated in the Marburg/Cappel sewage plant. The following parameters were measured: Concentrations of the metal ions of Cr, Cu, Pb, Cd, Fe, Ca and Zn; pH; conductivity; extinctions at 254 and 436 nm; phosphate, chloride and solids concentrations in the sample. Heavy metals (in solution and in bands) were eliminated in the following order: Cr(97%) > Pb(96%) > Cu(84%) > Zn(80%) > Ni(72%) > Cd(61%). Further, the effects of EDTA on the bonded and dissolved metal ions of iron(III), zinc(II), nickel(II) and copper(II) were investigated in a sewage sample. Resolution of bonded metals was observed only in the case of zinc. (orig.)

Abstract (German)

Es wurde das Verhalten von ausgewaehlten Stoffen waehrend der Abwasserreinigung in der Gruppenklaeranlage Marburg/Cappel untersucht. Folgende Parameter sind in das Messprogramm aufgenommen worden: Gehalte der Metallionen von Chrom, Nickel, Kupfer, Blei, Cadmium, Eisen, Calcium und Zink, der pH-Wert, die Leitfaehigkeit, die Extinktionen bei 254 und 436 nm, der Phosphat-, Chlorid- und Feststoffgehalt der Probe. Fuer die Elimination der Schwermetalle (geloest und gebunden) in der gesamten Klaeranlage ergab sich folgende Reihenfolge: Cr(97%) > Pb(96%) > Cu(84%) > Zn(80%) > Ni(72%) > Cd(61%). Weiterhin wurden die Auswirkungen von EDTA auf die gebundenen und die geloesten Metallionen von Eisen(III), Zink(II), Nickel(II) und Kupfer(II) in einer Abwasserprobe untersucht. Eine Rueckloesung der gebundenen Metalle war nur fuer das Zink zu beobachten. (orig.)
