| 摘要 |
The invention relates to an arrangement for producing a flow in a wastewater treatment tank (1), comprising a substantially horizontal bottom (B) and a horizontal mixer (2, 3, 4), which is provided in the wastewater treatment tank (1) and which has a propeller (4) driven by means of a propeller shaft (3). According to the invention, in order to save energy to produce flows, the axis (A) of the propeller shaft (3) is tilted relative to the bottom (B) by an angle α of 1 to 10° in such a way that a flow directed toward a surface (O) of the wastewater (W) can be produced by the horizontal mixer (2, 3, 4). |
