Abstract

The invention relates to a stirring device for activated sludges comprising a hyperboloid stirring body (1) attached to a shaft (2), wherein a plurality of transport ribs (3) are provided on the top (O) of the stirring body (1) running toward the circumferential boundary (UM) thereof, wherein the transport ribs (3) have an oblique course, at least in sections, relative to a radial direction, and wherein the oblique position of the transport ribs (3) is selected such that, when the stirring body (1) rotates in a predetermined rotational direction (R), a flow (S) is generated that is directed outward away from the circumferential boundary (UM) of the stirring body (1). In order to improve the efficiency of the stirring device, the invention proposes that a flow guidance device (7) for guiding the flow (S) generated by the stirring body (1) be provided in a plane running substantially perpendicular to the shaft (2), said flow guidance device surrounding the circumferential boundary (UM) of the stirring body (1) and being relatively fixed thereto.
