A flush mixing tank is provided with a flocculant mixing section in which a raw water a to be treated is introduced and a flocculant such as known aluminum sulfate or polychlorinated aluminum is injected, and then they are agitated and mixed; and a floc growing section through which flocculant injected water mixed with the flocculant passes, and the flocculant injected water is discharged as a floc treated water, but a water passing member, which is provided with a plurality of water through-holes for promoting the growth of the flocs in the flocculant injected water, is disposed in the floc growing section. Flocs of flocculant injected water can be rapidly formed, and growth of the flocs can be accelerated.

What is claimed is: 1. A flocculation apparatus comprising: a flow path for a flocculant injected water in which a flocculant is injected and mixed into raw water, and a ceramic honeycomb water passing member located in the flow path, the water passing member including a plurality of water through-holes through which flocculant injected water passes causing condensation of flocs. 2. A flocculation apparatus comprising: a tank, a flocculant mixing section located in the tank, a floc growing section located in the tank, and a ceramic honeycomb water passing member located in the floc growing section, the water passing member including a plurality of water through-holes, wherein a raw water and a flocculant are introduced and mixed in the flocculant mixing section into a flocculant injected water, and the flocculant injected water passes through the floc growing section while causing condensation of flocs. 3. The flocculation apparatus of claim 1, wherein said water passing member has an open area ratio of about 35 to about 90% a water through-hole length of about 500 to about 2000 mm, and a water through-hole diameter of about 1.5 to about 8.0 mm. 4. The flocculation apparatus of claim 2, wherein said water passing member has an open area ratio of about 35 to about 90% a water through-hole length of about 500 to about 2000 mm, and a water through-hole diameter of about 1.5 to about 8.0 mm. 5. A flocculation apparatus comprising: a flow path for a flocculant injected water wherein a flocculant is injected and mixed into raw water; a first water passing member located in the flow path, the water passing member including a plurality of water through-holes through which flocculant injected water passes causing condensation of flocs; and a second water passing member including a plurality of water through-holes, located in the flow path after the first water passing member, said second water passing member having a smaller open area ratio than the first water passing member. 6. The flocculation apparatus of claim 5, wherein the second water passing member has a smaller water through-hole diameter than the first water passing member. 7. The flocculation apparatus of claim 5, wherein the first and second water passing members are separated by a space. 8. The flocculation apparatus of claim 5, wherein the first and second water passing members comprise a ceramic honeycomb. 9. The flocculation apparatus of claim 5, wherein the first and second water passing members are separated by a space, and wherein the first and second water passing members comprise a ceramic honeycomb. 10. A flocculation apparatus comprising: a tank; a flocculant mixing section located in the tank; a floc growing section located in the tank; a first water passing member located in the floc growing section, the water passing member including a plurality of water through-holes, wherein a raw water and a flocculant are introduced and mixed in the flocculant mixing section into a flocculant injected water, and flocculant injected water passes through the floc growing section causing condensation of flocs; and a second water passing member located in the flow path after the first water passing member, said second water passing member having a plurality of through-holes with a diameter smaller than the through-holes of the first water passing member. 11. The flocculation apparatus of claim 10, wherein the first and second water passing members are separated by a space. 12. The flocculation apparatus of claim 10, wherein the first and second water passing members comprise a ceramic honeycomb. 13. The flocculation apparatus of claim 10, wherein the first and second water passing members are separated by a space, and wherein the first and second water passing members comprise a ceramic honeycomb.
