Description

(54) SEPARATION CAMERA

one

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

At present, constructions similar to the shower chambers of the common sewer system are used as separation chambers. The known construction of the chambers of rainfalls with one-sided and two-way side spillway, with a curved side spillway, with a frontal spillway 1, with a curvilinear frontal spillway 2.

The closest in technical essence to the invention is a vertical wall 3 shower chamber.

In this design, at flow rates exceeding the limit — the established flow of rainwater discharged for treatment — rain flow is completely discharged into the reservoir, while the treatment plant can accept the limit flow.

In addition, to transform the flow, when passing from a circular pipe to a rectangular tray, a transition section 5-6 V long is installed in the chamber, where B is the width of the tray, which significantly increases the dimensions of the chamber.

The purpose of the invention is to provide a more constant flow rate to the treatment plant and reduce the size of the facility.

This goal is achieved by the fact that the separation chamber with a vertical separation wall is provided with a water well located in front of the discharge pipe, and the separation wall is vertical with an opening.

FIG. 1 shows a schematic view of a separation chamber, section A-A in FIG. 2; in fig. 2 shows a section BB in FIG. one; in fig. 3 shows a comparative characteristic of the operation of a vertical-wall lavatory chamber and the proposed construction.

The separation chamber consists of a vertical shaft 1, round or rectangular in plan, in which a vertical separation wall 2 is installed with a culvert opening (neck) 3, a supply collector 4 and a diverter hole 5 of 5 downstream 6, a water well 7 and a rainwater outlet 8, in which excess rainwater is discharged into the reservoir. In order to prevent household wastewater from the interceptor collector 9 into the separation chamber, through the outlet 5 in the event of a blocking interceptor, a shield 10 can be installed on the wall of the outlet opening. the operation of the intercepting collector, the shield 10 hangs freely and does not interfere with the movement of water. If it is necessary to close the culvert slit 3, it can be closed with a hook 11. The presence of a vertical dividing wall, a culvert slit and a downstream site ensures the constant flow rate and, therefore, normal operation of pumping stations and sewage treatment plants. At the same time, there is no discharge of rainwater runoff into the reservoir until it reaches the marginal flow rate, which ensures that the first portions of the rainwater runoff that is most polluted are cleaned.
