The equipment has a main reactor (I) and an anterior reactor (II), as well as facilities for feeding in untreated sewage, removing cleaned water and sludge and aerating the wastewater entered into the main reactor, and a mixer (2) situated in the anterior reactor (II), and it is characterised by that between the main reactor (I) and the anterior reactor (II) there is a facility or there are facilities for the recirculation of wastewater In the course of the procedure, between the anterior reactor (II) and the main reactor (I) the waste-water aerated in the latter reactor and mechanically stirred in the former reactor is recirculated, and so the transformation of the nitrogen content of the biologically decomposable pollutants by nitrification takes place in the main reactor, while the biological elimination of the nitrates created in the course of the nitrification (denitrification) takes place in the anterior reactor, and as a result of the anaerobic processes biological phosphorus elimination is also ensured (FIG. 1).
Aerial advertising device for the presentation of pictures that change over time which contains an inflatable information-carrying body (90) that has a hollow internal space (92), a supporting structure (50) positioned in the internal space (92) of the information-carrying body (90), an image formation unit (10) connected to the supporting structure (50), as well as a power supply unit linked to the image formation unit (10) and a fixing unit (80) connected to the information-carrying body (90), the information-carrying body (90) has a filling opening (93) in connection with the internal space (92), furthermore, a group of markings (2) consisting of one or more characters and/or graphics is displayed on the information-carrying body (90), and at least a part of the group of markings (2) displayed on the information-carrying body (90) is formed by the virtual picture projected onto the internal surface (95) of the information-carrying body (90) with the assistance of the image formation unit (10), characterised by that the image formation unit (10) is formed by an ordered group of at least six projection devices (11, 12, 13, 14, 15, 16) permanently fixed in relation to the information-carrying body (90), the individual projection devices (11, 12, 13, 14, 15, 16) are connected to an image-storage and editing part-unit (30) via a data transfer channel (20), the supporting structure (50) has supporting plates (51, 52, 53, 54, 55, 56) that can be moved independently of each other, at least some of the individual projection devices (11, 12, 13, 14, 15, 16) are fitted to different supporting plates (51, 52, 53, 54, 55, 56), and at least one continuous part of the group of markings (2) is formed by the continuous group of picture elements (2a) projected by at least a group of some of the projection devices (11, 12, 13, 14, 15, 16) arranged in this way.
