<p>The present invention concerns a means for treating liquid, in particular waste water, comprising a body (1, 1a) consisting of a cylindrical and a conical part, a primary flow part (I) and a clarification part (6). The primary mixing (I) part of the treatment means is composed of a cylindrical inner cell (2) and a conical part (2a) immediately adjacent thereto, which have been so disposed that between the body (1, 1a) and the primary flow part (I) is left an annular gap in which passes a sludge flow (k), that inside the inner cell (2) is disposed a treatment tuber (3) wherein is disposed a flow generator (17) for guiding a supply (a) from the treatment tube (3) further as a flow (c) from the inner cell (2) to become a flow (e) to the clarification part (6), and a flow (1) to the discharge (7) of the conical part (6a) disposed around the inner cell (2), and, if needed, of lamellae cones (6b, 6c, 6d,...) for clarifying the flow (e) to become a downward flow (k) and a flow (f) to a pure liquid outlet (5), that in the treatment means is disposed a secondary flow part (II) external to the body (1, 1a), which guides the discharge flows (k, 1) into a divider (10) in which a partial flow (h) is removed and the remaining flow (k+1-h) is returned to circulation.</p> |
