[0002] Polluted sludge mainly comes from dredging of river channels, lakes, reservoirs, pipes and culverts. Polluted sludge contains a large amount of heavy metals, persistent organic pollutants, and pollutants such as nitrogen and phosphorus. If not properly treated, it will cause serious pollution to the environment. During the treatment process of polluted sludge, first, a dredging ship clears the sludge at the bottom of the river. The dredged sludge is preliminarily filtered and screened and then input into a solidification sedimentation tank for sedimentation. After a period of sedimentation, the water on the upper layer of the sedimentation tank is discharged, leaving the water and sludge at the bottom layer.
