Abstract: A water purification apparatus and a water purification method capable of effectively using a layered double hydroxide and easily being applied are described. A water purification apparatus for removing a polluted substance from polluted water includes a solid-liquid separator that separates the polluted water and a solid material from each other, and a polluted substance remover that removes, by a layered double hydroxide, the polluted substance contained in the polluted water separated by the solid-liquid separator.

Abstract: Producing a filtration body formed of a layered double hydroxide having a crystallite size of 20 nm or less carried on a carrier including a thermally fusible fiber is described. The carrier is prepared that has a first mesh carrier having a first mesh size and a second mesh carrier provided above the first mesh carrier. The second mesh carrier has a second mesh size larger than the first mesh size. A layered double hydroxide in the form of granules is supplied toward the second mesh carrier. The first mesh carrier carries the layered double hydroxide that has passed through the second mesh carrier. The carrier is shaken so that a portion of the layered double hydroxide (e.g., at least one granule) passes through the first and second mesh carriers. Thereafter, the layered double hydroxide carried on the first mesh carrier is adhered by thermally fusing the thermally fusible fiber.
