<p>Sewage processing assembly has at least one activated-sludge basin, with an intermittent aeration rotor supported by at least one float carrier. The float carrier (10), with the aeration rotor (8), is near a basin wall (3) at a vertical guide rail (11), to give it an adjusted height setting according to the sewage level (26) in the basin. The activated sludge basin, to process sewage, has a float carrier which projects at an angle from a vertical section (14) at the sliding guide, and a horizontal overhang (15) which holds the aeration rotor. The vertical section has two longitudinal carriers which move along the sides (12) of the vertical guide rail. The guide rail sides are linked by rungs (13) into a ladder. The vertical guide rail is mounted to the basin wall by brackets, to hold it at a gap from the wall surface. The longitudinal carriers of the float carrier are U-shaped to fit around the sides of the guide rail. The horizontal overhang is a platform formed by two side members linked by lateral carriers, and the platform is covered by a grid. The float (9) is fitted into the corner between the vertical and overhang sections of the float carrier. An Independent claim is included for an aeration rotor with a drive motor (17) to rotate the paddle wheel (16) round a vertical axis (18) which is shrouded within a housing, open at the bottom and with air inlet passages at the top.</p> |
