Title: Oil-containing wastewater separator and its method
Inventor: KATO YUJI
IPC: C02F1/36
Filed: 2020-08-26
Abstract: To provide a separator that can achieve both improved treatment efficiency and space saving when separating oil-containing wastewater from oil-containing scum.SOLUTION: An ultrasonic vibrator 4 is installed in a storage tank 2 so that an upper surface 4a of the ultrasonic vibrator 4 has an inclination angle of 20 degrees with respect to a liquid surface of an oil-containing scum Scoil. This prevents oil-containing drainage water Woil (separated water) separated from the oil-containing scum Scoil from remaining on the top surface 4a. In other words, since the oil-impregnated scum Scoil is always present on the upper surface 4a of the ultrasonic transducer 4, it is possible to promote the separation of the oil-containing drainage Woil (separated water) and dust from the oil-containing scum Scoil due to the cavitation effect. Since the ultrasonic transducer 4 is only installed in the storage tank 2, the oil-containing drainage Woil (separated water) and dust can be separated from the oil-containing scum Scoil with a space-saving and simple structure.SELECTED DRAWING: Figure 1
