Based on ultrasonic technology, different types of oily sludge produced in the oil industry were treated collaboratively, and the feasibility of its application was explored. The synergistic effect of mechanical vibration, ultrasonic cavitation and other units was used to realize the three-phase deep separation of oil, water and mud in different types of oily sludge. The test results show that the oil content of ground oily sludge is between 1% and 2%; the oil content of tank bottom oily sludge after treatment is less than 1%; the oil content of refinery oily sludge after treatment is between 2% and 5%; the oil content of other types of sludge after treatment is all less than 2%. After analysis, it was found that paraffin is the main factor affecting the ultrasonic treatment efficiency of ground oily sludge; the form and content of water are the key factors affecting the treatment effect of tank bottom oily sludge; the nature of refinery oily sludge and the parameters of ultrasonic are the important factors affecting its demulsification effect. The collaborative treatment process of ultrasonic technology is energy-saving, environmentally friendly and efficient, and can reduce the enterprise tax burden cost, hazardous waste transportation cost and disposal cost. However, its treatment effect on some specific types of oily sludge is still not ideal. In the future, ultrasonic technology combined with other advanced technologies, such as nanotechnology and biotechnology, is expected to develop more efficient and environmentally friendly oily sludge treatment methods.

探索基于超声波技术，利用超声波的机械振动、超声空化等与其他单元协同作用处理不同类型含油污泥，实现油泥中的油、水、泥三相深度分离的应用可行性。试验结果表明：处理后，落地油泥含油率在1%～2%；罐底油泥含油率低于1%；炼化油泥含油率在2%～5%；其他类型油泥处理后含油率全部低于2%。经分析得出：石蜡是影响落地油泥超声波处理效果的主要因素；水的存在形式和含量是影响罐底油泥超声波处理效果的关键因素；炼化油泥的性质和超声波的参数是影响其超声波破乳效果的重要因素。超声波技术协同处理过程不添加任何化学药剂，无二次污染且不产生增量；可以将不同类型油泥含水率降至40%以下。该技术实施后可降低企业税负成本、危废运输成本及处置成本。
