Conventionally known washing equipment, drying equipment and other equipment for car washing are respectively arranged at the upper part connecting the equipment 3 and the car washing equipment. In the ground, an intake 14 for collecting car washing drainage, and water separated from oil components are provided. A car wash drainage treatment device 16 provided with a discharge port 15 is embedded below the car wash machine 6. In the figure, reference numeral 17 denotes a keyboard for driving operation.

A car wash site 18 where the car wash machine 6 reciprocates and a car stops is placed above an oil tank 19 forming a car wash drainage treatment device 16, and a car wash drain inlet 14 provided at the left and right central portions. The slope is formed toward. Also,
A guide member 2 having an opening 20 below the inlet 14
1 are mounted, and baffle plates 22a, 22b, 22c, 22d, and 22e are alternately vertically projected in a staggered manner between the guide member 21 and the lower part of the oil tank 19. Further, the outlet 15 communicates with the oil-water separation device 8.

Next, the operation will be described. When the automobile is stopped at a predetermined position with respect to the car wash machine main body 11 and washing is started, the car wash drainage enters the oil tank 19 through the inlet 14 and the guide member 21. Here, the earth and sand that has adhered to the automobile is deposited on the lower part of the oil tank 19, and the oil contained in the wax and the like floats on the water to form an oil layer 31a on the upper part. The oil layer 31a is blocked by the first baffle plate 22a and does not flow to the discharge port 15 side, but accumulates here, and the oil that could not be floated here passes below the first baffle plate 22a. And rises along the second baffle plate 22b,
At this time, it floats on the water and the third baffle plate 22
c and an oil layer 31b is formed between them. Thus, baffle 2
The water from which the oil has been gradually removed by 2a to 22e flows to the discharge port 15 side communicating with the oil / water separator 8, and the oil / water separator 8 again performs drainage treatment and flows to the sewer. The discharged effluent can comply with water quality standards.
