Modern technologies of the removal of nutrients from sewage and the study of microbiological processes in their application

This work presents the results of microbiological studies aimed at exploring the deeper removal of ammonium nitrogen and phosphates from domestic wastewater. This document presents the results of the study of heterotrophic removal of ammonium nitrogen from wastewater for the single sludge technological scheme of biological wastewater treatment. We offered the method of deep wastewater treatment using feed material reinforced by steel wire. Steel wire in the feed material has a significant impact on the quantity and diversity of species composition of protozoans in activated sludge, and leads to intensive development of Chlorella sp. as well. © The Authors, published by EDP Sciences, 2017.
