Claims (1)

[Claims for Utility Model Registration] (1) A connecting protrusion formed by a plurality of contact materials 2 and arranged on at least one side of the contact substrate 3 of each contact material 2 at a required interval vertically. A plurality of first convex rows 5 consisting of 4 are provided at required intervals on the left and right, and a second convex consisting of convex portions 6 for preventing microbial sedimentation having a height lower than the height of the connecting convex portion 4. A part row 7 is provided between the first convex part rows 5, and the contact materials 2 are overlapped to connect the connecting convex parts 4 of the contact materials 2 that are adjacent in the front and back, and the contact substrate facing thereto. The portions 3a are joined to each other, and the convex portion 6 for preventing microorganism sedimentation of the contact material 2 adjacent to each other in the front and back, and the contact substrate portion 3 facing thereto.
A filling material for sewage treatment, in which a water passage gap 8 is formed between the filler material and the filler material. (2) A first convex portion composed of a plurality of contact materials 2 and consisting of connecting convex portions 4 arranged vertically at a required interval on both the front and back surfaces of the contact substrate 3 of each contact material 2. A plurality of rows 5 are provided at required intervals on the left and right, and a second row of convex portions 7 consisting of convex portions 6 for preventing microorganism sedimentation having a height lower than that of the connecting convex portions 4 is connected to the first convex row 5. It is provided between the convex rows 5, and the contact materials 2 are overlapped,
The connecting protrusions 4 of the contact materials 2 that are adjacent in the front and rear are joined to each other, and the microbial sedimentation prevention protrusions 6 of the contact materials 2 that are adjacent in the front and back and the contact substrate portions 3b that are opposite thereto are joined together. A filler for sewage treatment, in which a water passage gap 8 is formed between or between convex portions 6 for preventing microbial sedimentation that are opposed to each other.
