NOVELTY - Oil-containing sewage treatment control system comprises a power supply (1), a control module (2), an operation panel (3), a filter device (4) and a backwashing pump (5). The control module is specifically a control element and a programmable logic controller (PLC), and is connected with the power supply. The operation panel, filter device and back washing pump are connected with each other. The filter device is connected with the backwashing pump, which is connected to a sewage filtering device of backwashing tank. The sewage treatment control system is applied to sewage filtration system.    USE - Used as oil-containing sewage treatment control system.    ADVANTAGE - The control system: has simple structure and compact design; is not only suitable for sewage treatment of residential building, and also suitable for exploration and development of petroleum fields.    DETAILED DESCRIPTION - Oil-containing sewage treatment control system comprises a power supply (1), a control module (2), an operation panel (3), a filter device (4) and a backwashing pump (5). The control module is specifically a control element and a programmable logic controller (PLC), and is connected with the power supply. The operation panel, filter device and back washing pump are respectively connected with each other. The filter device is connected with the backwashing pump, which is connected to a sewage filtering device of backwashing tank. The oil-containing sewage treatment control system is applied to sewage filtration system of the filter device, and the control system requirements to process sewage filtering system is as follows: when the water in the filter is discharged to an exhaust valve, a drain valve is closed, the backwashing tank is opened, and backwashing water inlet valve and water outlet valve are opened to process backwashing. A control system basic program is provided with automatic and manual functions. When the device is in the automatic mode, a device is set according to the PLC program time interval. In the manual working mode, the control panel allows the operator to use the buttons on the control devices.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the oil-containing sewage treatment control system.    Power supply (1)    Control module (2)    Operation panel (3)    Filter device (4)    Backwashing pump (5)
