SU1214872A1 - Separating chamber - Google Patents

Description

The invention relates to sewage disposal devices with semidividual and combined sewage networks.

The purpose of the invention is to ensure the consistency of the discharge to the treatment plant, and to prevent floating substances from entering the pond.

Figure 1 shows a separation chamber, a longitudinal section; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 2; Fig. 4 shows the routing element with foam windows.

The separation chamber consists of a supply manifold 1 and a diverter 2 of smaller diameter. The discharge manifold 2 is flush with the inlet. The diamond-shaped drain device 3 is connected to inlet 1 and outlet 2 collectors and is made of reinforced concrete. Inside the spillway device 3 there is a semi-submerged stringer element 4 of a V-shaped form, the ribs of which are parallel to the walls of the drainage device 3 and have flow-through windows 5 of a triangular shape. The jet-guiding element 4 is made of reinforced concrete and is attached to the walls of the spillway device using semi-submerged foam-retaining boards 6, partially tie-back channels formed by the walls of the spillway device 3 and ribs of the diverting element D. Spill-over device 3

It has spillway windows 7 in the long walls along the liquid. At the bottom of the separation chamber, there is an interceptor collector 8. The separation chamber operates as follows.

The wastewater through the inlet manifold 1 enters the drainage device 3. At low flow rates, the wastewater freely enters the outlet manifold 2 of smaller diameter. At high flow rates, the stream is divided into three parts by the diverting core 4, while the lower part of the flow of floating substances passes under the diverting element 4 and enters the collector 2. The other two parts of the flow, containing floating substances, are guided by the edges of the diverting element and using shims 6 through suction ports 5 to the flow element 4. Excess water, cleaned from floating substances, is discharged through the spillway holes 7 and discharged by the discharge manifold 8 into the reservoir. Due to the implementation of the triangular-shaped foam ports 5, the most complete capture and entry of floating substances into the diverting element 4 is ensured.

Thus, the proposed separation chamber provides a constant flow rate for cleaning and retains floating substances. Design, compact in design.
