SETTLING TANK AND METHOD FOR GUIDING PARTIAL FLOWS IN THE INLET AREA OF SETTLING TANKS

摘要

In sedimentation basins (1) there are inlet structures (2), through whose height-adjustable inlet opening (3) the suspension flows to the basin. Depending on the current load, the volume flow flowing out of the inlet structure can be directed in addition to the height variability of the inlet opening by forming a horizontally flowed inlet opening (3a) or a vertically flowed inlet opening (3b) and optionally in horizontal and vertical partial flows Q sub I Split /sub and Q sub II /sub. As a result of the horizontal inflow, the capacity of the sedimentation basin increases when the load is high; due to the vertical inflow, the volume flow through the sedimentation space and the turbulent energy in the sedimentation space decrease at low load, so that the retention of fine suspensa in the sedimentation basin increases and thus the drainage quality is improved ,
