Description

Technical Field

[0002] In the sewage treatment system, the effective collection and removal of sludge is an important link to ensure the treatment effect. For example, as an important link in the sewage treatment process, a large amount of sludge often accumulates at the bottom of the secondary sedimentation tank in the sewage treatment process. If this sludge is not cleaned in time, it will not only affect the treatment effect of the secondary sedimentation tank, but also may cause the effluent water quality not to meet the standards. The current problems in the treatment of the secondary sedimentation tank are that the sludge treatment is not thorough in sweeping the sludge, and there is a lot of sludge residue; there are still many toxic and harmful impurities in the sludge to be scraped, which causes a burden on the subsequent resource utilization or treatment of the sludge; the sludge is easy to remain and adhere to the sludge treatment device, which affects the reuse.

[0003] Ultrasound plays an important role in sludge treatment. It can significantly improve the dewatering performance of sludge in a short time and reduce the volume of dehydrated sludge; the refractory organic matter in the sludge can be effectively decomposed, reducing the content of harmful substances; through the action of ultrasonic waves, the volume of sludge can be greatly reduced, and this effect helps to reduce the transportation and storage costs in the sludge treatment process; in addition, ultrasonic treatment does not require the use of a large amount of chemical agents, reducing the secondary pollution to the environment.
