Analiza raportów oddziaływania na środowisko oczyszczalni ścieków komunalnych

W pracy dokonano oceny analizy zagrożeń poszczególnych komponentów środowiska zawartych w wybranych raportach oddziaływania oczyszczalni ścieków w fazie eksploatacji. Analizowano treści merytoryczne ocen wpływu na poszczególne komponenty środowiska w raportach, jak i rzeczywistych zagrożeń, jakie powodują oczyszczalnie. Z uwagi na mnogość kryteriów oceniających wpływ oczyszczalni ścieków na środowisko do analizy zastosowano wielokryterialny model decyzyjny

This article presents an evaluation of Environmental Impact Assessments for municipal wastewater treatment plants during operation. The study was conducted on a sample of 11 assessments prepared between the years 2005 and 2012. The elaborations concerned wastewater treatment plants in the range between 400 and 120000 RLM, located in Poland. The said treatment plants were based on technologies using the classical activated sludge chamber method or with separated dephosphatization, denitrification and nitrification chambers, using sequential biological reactors or trickling beds. Having acquainted themselves with the contents of analysed assessments, the authors assigned component grades based on the assumed criteria. The grade aggregation was carried out using the following operators: Bayesian and Hurwicz criterion. The significance evaluation of variables was conducted using the paired comparison method from the investor’s and expert’s point of view. The article presents conclusions arising from conducted analyses and the authors’ own experience.
