Abstract:

The aim of the article was the analysis of the dephosphatation of wastewater in case of breakdown
of the aeration system. The changes in the phosphorus reduction in wastewater was analyzed. Apart from
this chemical indicator, the set of filamentous bacteria of the active sediment was also analyzed. Two
measurement sequences of the wastewater sediments were conducted. Each measurement sequence
represented different oxygenation conditions because the sediment was collected during a breakdown of the
oxygenation system and 3 weeks after its repair. The analysis of results lead to a conclusion that in the
examined active sediment in condition of lack of oxygenation, the percent of phosphorus reduction is lower
than in the case of improvement of the aerobic conditions. The microscopic analysis of filamentous bacteria
confirms the specific changeability according to the physical and chemical conditions in the wastewater
treatment plant.
