[0034] Under the elastic connection effect of the elastic connection member 502 of the connection mechanism 5, when the height of the wastewater in the sedimentation tank 1 exceeds the height of the isolation plate 301, the isolation plate 301 can be gradually suspended in the sedimentation tank 1, and in this process, the supernatant is gradually overflowed through the water permeable hole 4 to the upper side of the isolation plate 301, thereby effectively and obviously reducing the solid content in the supernatant on the upper side of the isolation plate 301, that is, reducing the solid content in the supernatant to be discharged, and further ensuring the reuse effect of the supernatant.
