摘要
A separation vessel for the separation of activated sludge from a waste water/activated-sludge suspension is provided in the centre with a pipe (7) open at the top and closed at the bottom by a base (9), into which pipe, in the vicinity of the base (9), an inlet (10) joined to the feed line (11) for the suspension opens. The central pipe (7) is surrounded at a distance by a second pipe (8) which is open at both ends, terminates beneath the liquid surface (20) and projects above the liquid surface (20) at the other end, as does the central pipe (7). The central pipe (7) is provided with a stirrer, the variable speed of rotation of which is adjusted to such a value that the suspension in the upper part of the pipe (7) forms a parabola of rotation which extends up to the edge and from which the suspension emerges over the edge. …IMAGE…
