FIELD: equipment of sewage purification. ^ SUBSTANCE: the invention is pertaining to equipment of sewage purification and may be used at biological purification of sewage in aerotanks with an active sludge. The tubular aerator contains a bearing pipe with radial holes and a dispersive coating with variables porosity and an average size of pores. Inside the dispersive coating along the bearing pipe there are laid rows of wire forming dilatational channels. At that the ends of the wire may be fixed in the bearing pipe at the butt sections of the aerator. The dispersive coating is formed by a strato-frame winding of treads. The technical result is an increased efficiency of aeration of the liquid and the more uniform distribution of the airflow inside the dispersive coating along the whole length of the aerator. ^ EFFECT: the invention ensures an increased efficiency of aeration of the liquid and the more uniform distribution of the airflow inside the dispersive coating along the whole length of the aerator. ^ 2 cl, 2 dwg |
