Revisão bibliográfica acerca do polimento final de efluentes agroindutriais aplicado a remoção de fósforo e nitrogênio

Abstract

Concerns about the intensive use and improper disposal of effluents have been increasing in recent years. Agroindustrial effluents, in addition to having a high load of organic matter, are rich in nutrients such as nitrogen and phosphorus. The amount of these nutrients in excess present in effluents from pig farming activities, slaughterhouses, dairy products is a cause of pollution resulting from the eutrophication process of aquatic environments, posing a threat to water resources and even human health. Thus, this study aimed to bring concepts of nitrification and denitrification and some biological processes used in the removal of nitrogen and phosphorus in agro-industrial effluents that can obtain good removal efficiencies and lower cost, such as the processes performed by anammox and wetlands.
