Activated sludge method dominates among the currently used biological wastewater treatment systems. The dynamic development of this technology implies need for research, most of which are carried out in laboratory conditions. Biolog system seems to be an effective tool that allows a quick assessment of microbial activity of activated sludge. The aim of this study was to verify Biolog® EcoPlates’ usage for comparing the functional and metabolic diversity of activated and excess sludge microbial communities, collected from WWTP “Klimzowiec” in Chorzów with the excess sludge subjected to the purification process, and then long-term adaptation in laboratory conditions. Changes in the functional diversity of activated sludge during the adaptation in the lab-scale were verified. It was found that the acclimatization process plays a crucial role in sludge adaptation to the laboratory environment. In addition, it has been shown that subjecting the excess sludge to purification may lead to changes in functional diversity of this community.

Wśród współcześnie stosowanych systemów biologicznego oczyszczania ścieków dominuje metoda osadu czynnego. Dynamiczny rozwój tej technologii implikuje konieczność prowadzenia badań naukowych, które w większości wykonywane są w warunkach laboratoryjnych. System BIOLOG wydaje się być skutecznym narzędziem, pozwalającym na szybką ocenę stanu aktywności mikroorganizmów osadu czynnego. Przedmiotem badań było zastosowanie płytek Biolog® EcoPlate do porównania funkcjonalnej różnorodności i aktywności metabolicznej zespołów mikroorganizmów, występujących w osadzie nadmiernym i osadzie czynnym, pobranym z Oczyszczalni Ścieków „Klimzowiec” w Chorzowie oraz w osadzie nadmiernym, poddanym procesowi oczyszczania, a następnie 7-tygodniowej adaptacji w warunkach laboratoryjnych. Sprawdzono także zmiany różnorodności funkcjonalnej mikroorganizmów osadu czynnego pobranego z oczyszczalni ścieków podczas hodowli w warunkach laboratoryjnych. Stwierdzono, iż proces aklimatyzacji odgrywa ważną rolę w adaptowaniu osadu czynnego do warunków laboratoryjnych. Wykazano również, że poddanie osadu nadmiernego procesowi oczyszczania może prowadzić do zmian różnorodności funkcjonalnej tego środowiska.
