Comparison of treatment technologies for highly concentrated nitrogen compound wastewater

Abstract

The flow of biogenic elements with wastewater into water bodies leads to an increase in the content of biogenic and organic compounds, a decrease in the oxygen content, the appearance of anaerobic zones, an increase in water turbidity, discoloration, pollution with microorganisms, including pathogenic ones, so the research area was the methods of treating wastewater that is highly loaded with nitrogen. Anammox process was considered as the most promising method of treating wastewater highly concentrated on nitrogen compounds. The analysis of the main existing technologies is carried out, the advantages, disadvantages and features of the application (operation) of these methods are revealed. The treatment of return streams as an alternative to the classical solution and an effective tool for improving the quality of wastewater treatment from nutrients is considered. The experience of implementation and operation of Anammox process at aeration stations in different countries is described.
