超声溶剂萃取法处理含油污泥的研究

以新疆克拉玛依的含油污泥为研究对象．先后在超声条件下通过有机溶剂萃取和表面活性剂水洗的方法对其进行综合处理。结果表明：在处理温度为55℃、超声强度为320W、处理时间为5min、溶剂比为7．5L·g。的最佳条件下，有机溶剂石油醚萃取处理后含油污泥的剩余含油量降为6％；在处理温度为55℃、超声强度为320W、处理时间为llmin、溶剂比为15．0L·g^-1、pH值为5的最佳条件下．十二烷基苯磺酸钠-OP-10（1：1）处理后含油污泥的剩余含油量仅为0．6％。

Research on Oily Sludge Treatment by Ultrasonic Solvent Extraction

Using oily sludge from Karamay Oilfield in Xinjiang as research object,the treatment conditions were optimized for oily sludge with organic solvent extraction and surfaetant washing under ultrasonic condition through the single factor experiment. When the oily sludge was extracted by petroleum ether under the optimum conditions as follows： treatment temperature of 55 ℃, ultrasonic intensity of 320 W, treatment time of 5 min.,liquid-solid ratio of 7.5 L · g^-1 ,the residual oil content decreased to 6%. And when the oily sludge was furtherly washed by SDBS-OP-10（1 ： 1）under the optimum conditions as follows： treatment temperature of 55 ℃ ,ultrasonic intensity of 320 W,treament time of 11 min,liquid-solid ratio of 15.0 L · g^-1 ,pH value of 5, the residual oil content was only about 0.6 %.
