An oil-water separating equipment which almost completely separates waste oil and wastewater in stages by controlling a series of sensors and pumps, and can discharge the purified wastewater by separately purifying wastewater is provided. An oil-water separating equipment comprises: a waste oil and wastewater storage tank(100), a waste oil and wastewater separation tank(200), a wastewater purification tank(300), a waste oil storage tank(400) and a controller. The waste oil and wastewater separation tank receives waste oil(O) and wastewater(W) from the waste oil and wastewater storage tank through a first supply pipe(110), and has an oil level upper limit sensor(210), an oil level lower limit sensor(230), a water level prediction sensor(240) and a water level lower limit sensor(250) sequentially installed from an upper part to a lower part along one side of an inner wall thereof with being spaced from one another in a predetermined distance. The waste oil and wastewater separation tank further has a water level prediction sensor(220) installed above the oil level lower limit sensor, a wastewater discharge pump(270) connected to a first discharge pipe(260), a waste oil discharge pump(290) connected to a second discharge pipe(280), and an oxygen generator(292) connected to an oxygen supply pipe(291). The wastewater purification tank has a water level upper limit sensor(310) and a water level lower limit sensor(320) formed on upper and lower portions of an inner wall thereof, a microorganism supply tank(330) installed on an upper end of the inner wall thereof, a wastewater discharge pump(370) installed in a lower part therein and connected to a heater(340), a temperature sensor(350) and a third discharge pipe(360), and an oxygen generator(390) connected to an oxygen supply pipe(380). The waste oil storage tank has an oil level upper limit sensor(410), an oil level prediction sensor(430) and an oil level lower limit sensor(420) sequentially installed from an upper part to a lower part along an inner wall thereof. The waste oil storage tank further has a waste oil discharge pump(450) installed in a lower part therein and connected to a fourth discharge pipe(440). |
