The wastewater needs to pass through the water inlet 11 through a pipeline and then enter the sedimentation tank 1. When wastewater flows in the pipeline, impurities with high density in the wastewater, such as muddy sand, cement slurry and the like, can naturally settle at the bottom of the pipeline, so that the condition that the impurities in the wastewater at the upper part of the pipeline are less and the impurities in the wastewater at the lower part of the pipeline are more occurs. And due to different impurity contents, a laminar flow phenomenon that the flow velocity of the wastewater at the upper part of the pipeline is faster and the flow velocity of the wastewater at the lower part of the pipeline is slower can be formed.

The sedimentation tank 1 of this embodiment is through setting up water diversion plate 2, is the waste water that the impurity is less through diaphragm 21 upper portion, and is the waste water that the impurity is more through diaphragm 21 lower part to with impurity more and impurity less upper strata waste water and lower floor's waste water separation, lower floor's waste water is guided downwards by riser 22, and lower floor's waste water flows downwards to the bottom of sedimentation tank 1, reduces the horizontal flow of impurity more lower floor's waste water in sedimentation tank 1, accelerates the sedimentation of impurity.
