OIL-WATER SEPARATION DRAINAGE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an oil-water separation drainage system which can separate away oil contained in water to be treated, with a relatively simple structure. SOLUTION: The oil-water separation drainage system comprises first to fifth oil-water separation tanks 14-22 provided in series. Water to be treated is supplied into the first oil-water separation tank 14. Oil and water are separated while the water to be treated flows from the first oil-water separation tank 14 to the fifth oil-water separation tank 22. The water from which the oil has been separated away is discharged outside from the fifth oil-water separation tank 22. The first oil-water separation tank 14 is provided with an oil detecting sensor 26 and a first oil adsorbing member 28, and the fifth oil-water separation tank 22 is provided with a drainage pump 32. When the oil detecting sensor 26 detects oil, the operation of the drainage pump 32 is stopped to stop the water discharge from the fifth oil-water separation tank 22. The oil contained in the water to be treated is adsorbed by the first oil adsorbing member 28. COPYRIGHT: (C)2009,JPO&INPIT
