The invention provides improved elliptic fold solid-liquid separation equipment comprising a natural dewatering section and a squeezing dewatering section, wherein a squeezing plate comprises a first squeezing section positioned in front of a treated object conveying direction and a second squeezing section positioned behind the treated object conveying direction; the first squeezing section and the second squeezing section are connected with each other to form a bent structure; an included angle alpha 1 between the connecting line from the head end to the tail end of the first squeezing section and a carrying surface of the squeezing dewatering section is bigger than an included angle alpha 2 between the connecting line from the head end to the tail end of the second squeezing section and the carrying surface of the squeezing dewatering section; the minimum height from the first squeezing section to the carrying surface of the squeezing dewatering section is not smaller than the maximum height from the second squeezing section to the carrying surface of the squeezing dewatering section; and the height from the lowest point of the connection part between the first squeezing section and the second squeezing section to the carrying surface of the squeezing dewatering section is bigger than the height from the tail end of the second squeezing section to the carrying surface of the squeezing dewatering section. The improved elliptic fold solid-liquid separation equipment provided by the invention can be used for quickly discharging the water squeezed out of treated objects, thereby improving the solid-liquid ratio of the treated objects.
