Currently, during sewage treatment, corresponding sewage treatment devices are required.

[0003] Currently, during sewage treatment, the sewage is first introduced into the treatment device, and then the treatment agent is added to the sewage for sewage treatment operations. After the sewage treatment is completed, the treated sewage is discharged through the drainage pipe. However, during the static settlement process of the sewage treatment, the sludge in the sewage adheres to the inner wall of the treatment device. Currently, the sludge is cleaned by manually holding a water pipe to impact the sludge with clean water, thereby cleaning the sludge.
