The invention provides an ellipse superposition solid-liquid separation apparatus. The apparatus comprises a natural dehydration segment used for bearing and conveying a processed material and gradually realizing natural hydration of the processed material in the bearing and conveying process, and a squeezing dehydration segment used for receiving the processed material naturally dehydrated by the natural dehydration segment, further realizing squeezing dehydration on the processed material by using a squeezing board and discharging, a ratio of the total area of water drainage gaps arranged on a natural dehydration segment carrying surface to the total area of the natural dehydration segment carrying surface is greater than 1:10 and smaller than 4:10, a ratio of the total area of water drainage gaps arranged on a squeezing dehydration segment carrying surface to the total area of the squeezing dehydration segment carrying surface is greater than 1:15 and smaller than 1:5, a ratio of the length of the natural dehydration segment to the length of the squeezing dehydration segment is greater than 1:1 and smaller than 4:1, and the length of the natural dehydration segment is at least 1.5m; and the processed material conveying speed of the natural dehydration segment and the processed material conveying speed of the squeezing dehydration segment are not greater than 0.3m/s respectively. The ellipse superposition solid-liquid separation apparatus has the advantages of compact structure, high dehydration efficiency and good stability.
