Ecological effects of multi-annual activities of the Sewage Treatment Plant of the potato industry plant in Iława

Abstract

The study contains materials on the functioning of the sewage treatment plant of the Potato Industry Plant in Iława. Potato wastewater, with a large load of organic pollutants, was discharged via pipeline to forest areas (fresh coniferous forest Peucedano-Pinetum), and then sprinkled in forest habitat using a system of pipelines and sprinklers. The paper presents the reaction of vegetation and forest habitat to the impact of sewage as well as the ecological consequences of this impact. In addition, the process of spontaneous regeneration of disturbed forest habitat after cessation of irrigation with sewage was shown.
