Abstract
A sewage water installation has a discharge basin in which is arranged a screening unit linked to a back-and-forth movable cleaning carriage. The discharge basin (20) is subdivided by a partition (24) and by the screening unit (30) into a storage chamber (25') and an outflow chamber (25"). The storage chamber (25') is linked to an inflow pipe (26) and to an outflow pipe (27) and the outflow chamber (25") is linked to an outflow pipe (28). In order to increase the storage volume and to reduce the throughflow speed, a retaining element (40) is arranged on the back-side of the screening unit (30), as seen in the direction of flow, inclined so as to form an angle therewith.
Claims13
Waste water plant, comprising a discharge basin (20, 120), connected to at least one inflow pipe (26;
- 126) and at least one outflow pipe (28, 128),
- a mesh screen unit (30, 130), which is disposed in said discharge basin and which includes a mesh screen having parallel screen bars and a cleaning car, which is movable back and forth and to which is attached a cleaning comb, which is arranged with teeth located between the screen bars of the mesh screen,
- a partition (24, 124), positioned within the discharge basin (20;
- 120) and subdividing the discharge basin into an inflow space (25';
- 125') and an outflow space (25";
- 125") wherein the mesh screen unit (30;
- 130) is attached to the upper edge of the partition (24;
- 124) such that the mesh screen unit is one of standing upright and upwardly inclined from a vertical plane at an angle of less than 90.degree. and
- a damming element increasing the volume of impoundment and arranged in the direction of flow behind the mesh screen unit (30;
- 130), said damming element having an upper edge which lies above the lower edge of the mesh screen unit.
