The invention relates to a device for the disposal of wastewater by networks of a semi-compartmental sewage system.

Fig. 1 schematically shows a d, separation chamber; figure 2 - section aa in figure 1; on fig.z section bb in figure 2; Fig. 4 is a detail of a self-cleaning grate.

The separation chamber consists of a Q vertical rectangular shaft 1, in which a vertical separation is installed, a wall 2 located at the end wall 3 of the shaft 1 of the inlet 4 and in the opposite 5 of the shaft 1 of the outlet 6 of the rainwater pipelines 7, the sewer 7 gratings 8, a jet shaped in the form of an axial line at maximum flow parameters, and an oper-20 with one side 9 on a vertical dividing wall 2 and another side 10 - on board 11 of tray 12 for removing soils, the other board 13 In the form of a spillway with a 25 thin wall, having openings 14, enclosing vertical partitions 15, and tray 16 for draining purified water, which is made narrowing-f from the width of the grate 8 to the diameter of the water pipeline 6.

The device works as follows.

Sewage water in dry weather (when pouring and washing streets) and the first portions of the most polluted rainwater supplied by the inlet pipe 4 enter the sewage collector 7. When the rain intensity increases, the stream from the supply pipeline 4, Mine vertical wall 2, falls on the grid 8, which retains insoluble impurities.

contained in stormwater. The water filtered through the grate 8 enters the tray 16 and is discharged from the pipeline 6. The insoluble impurities retained by the grate 8 under the influence of the fluid flow and its own weight slide into the tray to drain the soils with a slope towards the sewer collector 7 and enter the sewer collector. During heavy rain showers, after tray 12 is filled, the upper, cleaner water through board 13 enters tray 16 and is discharged into the reservoir. Filling tray 12 with water ensures that it is flushed.
