Abstract

Invenţia este destinată tratării apelor uzate, în particular epurării apelor uzate municipale şi industriale.Procedeul de epurare a apelor uzate prevede tratarea lor biologică cu presiune cu reducerea ulterioară a presiunii până la un astfel de grad, ca aceasta să rămână mai înaltă decât presiunea exterioară. Totodată reducerea presiunii este utilizată pentru evacuarea corpurilor solide prin flotaţia cu gaz rarefiat, precum şi pentru declanşarea procesului de filtrare şi/sau dezinfectare. Tratarea biologică sub presiune include adăugarea oxigenului şi nitrificarea biologică a apelor uzate pentru eliminarea substanţială a amoniacului.Instalaţia de tratare a apelor uzate prevede mijloace, care asigură realizarea metodelor procedeului.
