Sewage treatment by broadband ultrasound is a new technique developed in recent years. Although the theory research of the ultrasound technique in sewage treatment has been achieved great progress , the application just starts and is still in the laboratory phase. According to the characteristic of the high pollution index and the low degradation of the sewage in medium -and -small -sized enterprises , a new type high efficiency and low cost broadband ultrasound sewage treatment equipm ent is studied and developed to meet the sewage treatment demand (of the medium -and -small -sized enterprises ) . The equipment is composed by spray injector , h igh /low frequency transducer , frequency converter tube , reactor, sedimentation pot, aeration tank, and air deflector . The structure is compact , and the equipment is multi -functioned. It can be used separate ly or together with other sewage treatment equipment to make the effect distinct ly. According to the existing condition, three different f requency transducer s are employed. The diameter and effective height of the reactor actualize the broadband ultrasound by the frequency conver
