Ocena przydatności osadów ściekowych z Oczyszczalni Ścieków w Lubartowie do rolniczego wykorzystania

Abstract

The studies aimed to evaluate the possibilities for agricultural management of sewage sludge from Municipal Sewage-Treatment Plant in Lubartów. The content of Cu, Cr, Cd, Ni, Pb, Hg, Mg, Ca, N, P, K as well as disease-forming microorganisms (Salmonella rods, Toxocara spp., Ascaris sp., Trichuris spp.) were determined. It was found out that the studied sludge was characterized with high fertilization value comparable to manure. Sludge included slight amounts of heavy metal ions, and they were very rich in nitrogen, phosphorus, calcium and magnesium. No disease-forming microorganisms were detected in sludge. Sludge from Sewage Purification Plant in Lubartów may be an alternative source of organic matter and some nutrients, as well as perfect substrate for soil humus formation.
