摘要： The invention relates to a waste water treatment plant including at least a multi-step water treatment reactor arranged for receiving influent waste water, for carrying out at least a biological step and a sedimentation step and for providing effluent pure water, by means of an effluent weir. The wastewater treatment plant further includes means for increasing the sedimentation velocity, and means for hindering floating elements to get into the effluent weir.

摘要： The invention relates to a waste water treatment plant comprising at least a multi-step water treatment reactor (1; 101) arranged for receiving influent waste water, for carrying out at least a biological step and a sedimentation step and for providing effluent pure water, by means of an effluent weir (4; 41, 42, 43), characterized in that there are provided—means for increasing the sedimentation velocity (6), and—means for hindering floating elements (10) to get into the effluent weir (8; 81, 82, 83).
