PROBLEM TO BE SOLVED: To provide a solid-liquid separation facility which can effectively transfer sediments while suppressing an increase in construction cost by utilizing an inclined plane even when a pool width is large.SOLUTION: A solid-liquid separation facility comprises a sand basin 11 that makes sand contained in received sewage settle down, a pump well part 12 where a lift pump P3 is installed, and a junction part 13 that combines the sand basin 11 with the pump well part 12, the sand basin 11 having a plurality of troughs 31 arranged in the pool width direction by extending in a direction orthogonal to the pool width direction, sand collecting nozzles 71 that move sediments in the extension direction of the troughs 31, and inclined planes 32 respectively extending obliquely upward from a pair of upper edges 311 that demarcate the opening of the trough 31, and a connection part 33 with which the inclined plane 32 extending from the upper edge 311 of one trough 31 of the two troughs 31 adjacent to each other in the pool width direction and the inclined plane 32 extending from the upper edge 311 of the other trough 31 communicate has a height less than the height of the junction part 13.SELECTED DRAWING: Figure 3 |
