PROBLEM TO BE SOLVED: To provide a filtration apparatus in which solid-suspended water such as muddy water of a lake, a marsh, a pond, a river or the like and the dirty water to be generated at various construction/civil works such as river construction work and sewerage works is recovered and filtered so that suspended solids are separated/recovered and the filtrate is used effectively as agricultural water, industrial water or the like, which can be operated continuously over a long period of time and which is excellent in stability of filtration performance, durability and maintainability. SOLUTION: The filtration apparatus is provided with: a filtration tank in which solid-suspended water is stored; a solid-suspended water supply part for supplying solid-suspended water to the filtration tank from a spray nozzle part arranged at the internal bottom of the filtration tank; a disk-shaped ceramic filter which is arranged in the filtration tank and from the center hole side of which the filtrate obtained by permeating solid-suspended water through the ceramic filter from the outside surface thereof is discharged; a hollow pipe which is inserted/fixed in a center hole of the ceramic filter and through which the filtrate permeated through the ceramic filter is discharged; a discharge part connected to the hollow pipe for discharging the filtrate to the outside of the filtration tank; and a suspended solid recovery mechanism which is arranged to be slid freely at the internal bottom of the filtration tank and has a scraper.
