Wykorzystanie komunalnych osadów ściekowych z oczyszczalni ścieków w Aleksandrowie Kujawskim

The problems resulting from increasing amounts of deposited sewage sludge have lead to launching studies concerned with their biological and agricultural utilization. Such sewage sludge can be applicable in agriculture as long as the following four rules are respected and obeyed: a good agricultural practice is maintained, a long-term soil productivity is preserved, public nuisance due to sludge application is eliminated, and last but not least, all the regulations concerned with protection of underground waters, safety of both human and animal health, as well as soil environment are observed. The paper presents the results of an experiment in which compost based on a biological sludge from a municipal waste treatment plant in Aleksandrów Kujawski were applied as fertilizers.
