This is a secondary separation chamber formed between the partition wall 4 of . 7 is a water inlet attached to the casing A partition wall 4 as shown in the figure; 8 is a tertiary separation chamber provided in the casing A at the lower part of the partition wall 4;
Although not shown in the tertiary separation chamber 8, an oil separation element communicating with the water inlet 7, a clean water outlet, and an oil outlet are provided in the same manner as in the conventional device. Reference numeral 9 denotes an oil outlet protruding from the upper part of the side wall of the rough separation chamber 2, and the inner diameter of the oil outlet 9 becomes smaller as it goes outward. The tips of the nozzles, which will be described later, are concentrically opened. Reference numeral 10 denotes an oil discharge control valve installed on the small-diameter outlet side of the oil outlet pipe 9, and the oil discharge control valve 10 detects an oil content by an oil detector (not shown) provided at an appropriate position of the oil outlet 9. It is designed to open and close depending on the signal. Reference numeral 12 denotes an oil riser pipe installed at a suitable position on the upper side wall of the secondary separation chamber 3, and the oil riser pipe 12
A backflow prevention device, such as a check valve 13, is interposed in the middle of the oil outlet pipe 9.
The nozzle 14 at the tip of the nozzle 14 extends into the inside of the oil outlet pipe 9 in a fluid-tight manner.
At the inlet, it opens concentrically with the oil extraction pipe 9. (See Fig. 3) The oil that is separated from the waste water and floated to the surface by the oil separation element 6 in the secondary separation chamber 8 is collected by ascending the oil rising pipe 12 and passing through the tip nozzle 14 to the small diameter oil extraction pipe 9. When the oil is discharged to the oil outlet, a suction force is generated by an ejector-type nozzle mechanism formed by the tip nozzle 14 and the small-diameter inlet of the oil extraction pipe 9.

ら系外へ排出される。 One embodiment of the device of the present invention is constructed as described above, and when mixed sewage of oil and water is introduced into the casing A from the sewage intake port 1, the sewage is transferred to the coarse separation chamber 2.
The oil thus roughly separated collects near the upper top wall of the rough separation chamber 2, and when the oil discharge control valve 10 is opened in response to a signal from an oil detector (not shown), the oil is separated. The oil is discharged to the outside of the system through the oil outlet pipe 9. On the other hand, sewage containing oil that is not separated in the rough separation chamber 2 and water separated in the rough separation chamber 2 enter the oil separation element 6 in the secondary separation chamber 3 through the water inlet 5. The oil that is separated and floats up in the oil riser pipe 12 is discharged from the tip nozzle 14 toward the small-diameter inlet of the oil take-off pipe 9, creating a suction force and increasing the oil content in the secondary separation chamber 3. The oil is sucked and discharged together with the oil in the crude separation chamber 2 to the outside of the system. In this case, the check valve 13 installed in the oil riser pipe 12 allows the oil separated in the rough separation chamber 2 to
This serves to prevent oil from flowing backward in the riser pipe 12. Note that the oil-containing wastewater introduced from the water inlet 7 into the tertiary separation chamber 8 and the water separated in the secondary separation chamber 3 are separated into clean water by an oil separation element, as in the conventional system. The clean water is taken out of the system through the outlet, and the oil is discharged out of the system through the oil outlet.

An oil riser pipe 12 is provided on the upper side wall of the crude separation chamber 2.
According to the present invention, the oil collected in the upper part of the secondary separation chamber 3 and the oil in the upper part of the secondary separation chamber 3 are discharged out of the system from a single oil extraction pipe 9. The oil outlet, oil detector, oil discharge control valve, etc. provided at the upper part of the side wall of the secondary separation chamber are no longer necessary, and these components can be used in common with those of the coarse separation chamber. Therefore, compared to conventional devices, the number of parts is reduced by that amount, which not only reduces costs, but also provides practical effects such as easier control of the device and less risk of failure.
