摘要：
This paper presents the evaluation of impact of sewage sludge treatment on its quality. Contents of heavy metals (Pb, Zn, Cu, Cr, Ni, Cd) and their fractions, in two groups of sewage sludge: stabilized with and after fermentation, were investigated. Highest amount of the analyzed metals, in both groups of sewage sludge, were present in fractions in which they were strongly bound - III, IV, V, but in different order for each group. Differences were also noticed in amount of bounded metals in fractions which are dangerous for environment - I and II.
