WATER DISCHARGE SYSTEM WITH CONTROLLED INFLOW TO A SEWERAGE PUMPING STATION Russian patent published in 2022 - IPC E03F1/00 E03F3/02 E03F5/14 

FIELD: treatment of water.

SUBSTANCE: method relates to the field of water discharge systems. The system comprises a waste water transportation unit containing a collector, a water discharge network, and an overflow pipeline. The overflow pipeline is made in the form of a section of the network. The system is additionally equipped with a control pipeline, a compensation pipeline, a mechanical grid with a mechanical grid cleaning mechanism, an electric drive of the mechanical grid cleaning mechanism, at least two level sensors, one inlet and one outlet wells, a unit for controlling the mechanical grid cleaning mechanism, a receiving tank of the pumping station of sewage treatment facilities. The water discharge network and/or collector are connected in the inlet well with a compensation pipeline with a diameter D_k. The compensation pipeline is connected with the control pipeline with a diameter D_p in the outlet well, D_k≥D_p. The outlet well and the receiving tank of the pumping station of sewage treatment facilities are connected by the control and overflow pipelines. The tray of the overflow pipeline is located above the apex of the control pipeline. The mechanical grid with the cleaning mechanism is located in the outlet well. The level sensors are located in the outlet well before and after the mechanical grid. The outputs of the level sensors are connected with the input of the control unit of the mechanical grid cleaning mechanism. The output of the control unit of the mechanical grid cleaning mechanism is connected with the electric drive of the mechanical grid cleaning mechanism.

EFFECT: indicators of environmental safety are increased.
