Abstract
Purification of urban wastewater traditionally takes place at biological treatment plants, which were built in the 60s and 70s of the last century and are still being operated in populated areas of Ukraine. Today's wastewater contains high concentrations of surfactants, organic compounds, biogenic substances and other pollutants from enterprises that exceed the permissible concentrations at the entrance to treatment plants, which leads to ineffective treatment in traditional biological treatment schemes. It was this fact that became one of the main reasons for exceeding concentrations of nitrogen and phosphorus compounds in water sources. Therefore, in order to intensify wastewater treatment, it is necessary to choose more effective methods of wastewater treatment and to design structures that will ensure their proper treatment. The work considers the microbiological processes that will take place in the proposed design of the bioreactor.
