%X A technology for ultrasouic extraction process using gasoline as an extracting agent for oily sludge treatment was developed.The regulator,flocculant and emulsion breaker were selected and the process conditions such as extraction temperature,extraction time,ultrasound frequency and ultrasound power were determined.The result show that the 83.7% of oil in oily sludge was recovered under the following conditions: adding oil-field wastewater as a regulator,v(extracting agent)∶ v(regulator)∶ v(oily sludge)=4∶ 4∶ 1,extraction temperature of 40℃,extraction time of 15 min,ultrasonic frequency of 40 kHz and ultrasonic power of 150 W.
