| 摘 要： | 应用超声强化技术,对以汽油为萃取剂的超声萃取法处理含油污泥的工艺进行了研究,筛选了调整剂、絮凝剂、破乳剂,探讨了萃取温度、萃取时间、超声频率、超声功率等对处理效果的影响。结果表明:在调整剂为采油废水、物料配比为v(萃取剂)∶v(调整剂)∶v(油污泥)=4∶4∶1的条件下,萃取工艺为萃取温度40℃、萃取时间15 min、超声频率40kHz、超声功率150 W时,可回收含油污泥中83.7%的油品。

| Abstract: | 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. |
