<p>1. Apparatus for the aerobic biological purification of waste waters according to the combined filtration-activation method, with at least one submerged filter (1) rotating about a longitudinal axis (3) and submerged to the greater part in the waste water, which includes laminar growth bodies (33) as substrates for a so-called biological hotbed, wherein several growth bodies (33) are held mutually spaced by means of spacing elements, are combined into a growth body assembly (24 to 30) and are secured in a supporting construction of the filter (1), wherein the filter (1) has conversion chambers (42) arranged parallel to and spaced from its longitudinal axis (3) and wherein each conversion chamber (42) is provided in its inner (43) and its outer (44) walls, relative to the longitudinal axis (3), with at least one aperture (50; 49, 56, 57) for the passage of waste water and air and is otherwise closed, characterized in that each conversion chamber (42) is defined by two adjacent separate laminar growth bodies (33).</p> |
