超声技术能够产生空穴效应，然后生成·OH等活性物质，进而氧化分解难降解有机污染物，但是去除效率很低。为了提高超声技术的去除效能，可以采用与其他技术联用的方式。介绍了超声-臭氧法、超声-电化学氧化法、超声-光化学氧化法、超声-天然固体颗粒法等组合工艺，这些组合工业均表现出良好的去除效能；超声均相芬顿技术、超声非均相芬顿技术的应用更为广泛，其中超声非均相芬顿技术的优势明显。通过深入剖析超声联用技术的优势可以看出，超声联用技术在特种工业废水处理中效果显著。

Ultrasound technology can generate hole effects, which generates active species such as -OH that oxidize and decompose refractory organic pollutants.But the removal efficiency is low.In order to improve the removal efficiency of ultrasound technology, it can be combined with other technologies.The combined processes including ultrasonic-ozone, ultrasonic-electrochemical oxidation, ultrasonic-photochemical oxidation and ultrasonic-natural solid particles are introduced, and which all show good removal efficiency.Furthermore, ultrasonic-homogeneous Fenton technology and ultrasonic-heterogeneous Fenton technology are more widely used.Among them, ultrasonic heterogeneous Fenton technology has obvious advantages.The advantages of ultrasonic combined technologies are deeply analyzed.It can be seen that ultrasonic combined technologies have a remarkable effect on the treatment of special industrial wastewater.
