Characteristics and nature usability of municipal sewage sludges in Dolnośląskie Voivodeship

Journal Title: CHEMIK nauka-technika-rynek - Year 2015, Vol 69, Issue 8

Abstract

The article sums up real results of studies on sewage sludges obtained in years 1998–2012 from over 20 sewage treatment plants in South-West Poland – which provides an outlook on the real situation in this economy sector of waste management. The study results demonstrate among others drop in heavy metal contents in the recent years and increase of the main nutrient components – nitrogen and phosphorus in sewage sludges and also decrease of dry mass with simultaneous increase of the organic substance share. On the basis of obtained results it was ascertained that after aerobic sludge stabilization the sediments feature increased concentration of heavy metals in comparison with the sludges after digestion. Only 10% of sediments was excluded from the possibility of utilization for the nature purposes.
