Abstract: The article describes the main methods of phosphorus removal from municipal wastewater, such as reagent, chemical-biological and biological methods. The types of reagents used in the reagent and chemical-biological method for the removal of phosphorus are considered, their doses are determined and the effectiveness of the application is given. The process of phosphorus removal using biological technological schemes due to the alternation of anaerobic environment with aerobic is described. The use of special microorganisms Acinetobacter in the biological purification method is described, and the process of cultivation of these microorganisms in activated sludge is also considered. The removal efficiency is given, as well as the residual concentrations of phosphorus compounds in the liquid. The advantages and disadvantages of the methods are indicated. The technology of phosphorus removal from municipal wastewater is assessed. The economic comparison of the use of the reagent and biological method is given.
Keywords: eutrophication, reagent method, chemical and biological method, biological method, reagents, orthophosphates, phosphorus, acinetobacter, bioreactor.
