It is attached to each mountain portion of the net plate 1. [Effect] It was possible to provide a septic tank contact material that can be handled in a compact state as necessary and that can be easily assembled and used in a state where the contact efficiency with the water to be treated is good.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a septic tank contact material that is placed in a tank to be brought into contact with water to be treated and to fix microorganisms that perform biological treatment of the water to be treated.

[0002]

[Prior art]

 Conventionally, a flat plate-shaped perforated plate, a corrugated plate-shaped perforated plate, or a corrugated plate-shaped non-porous plate has been used as the contact material for the septic tank of this type.

[0003]

[Problems to be solved by the device]

 However, the contact material for septic tanks that uses a flat plate perforated plate has a smaller surface area per unit volume when assembled than the corrugated plate-shaped contact member, so contact efficiency with treated water is poor, and storage and transportation are also difficult. A wide space is required for loading and unloading. In particular, there was a drawback that it was difficult to handle when assembling in a narrow space. Further, since the corrugated plate-like porous plate or the corrugated plate-like non-porous plate is bulky, there is a drawback that it is difficult to store, transport, unload and assemble. Therefore, an object of the present invention is to provide a septic tank contact material that can be handled in a compact state as needed at the time of assembly, etc., and can be assembled and used in a state where the contact efficiency with the water to be treated is good. To do.

[0004]

[Means for Solving the Problems]

 In order to achieve this purpose, the characteristic structure of the septic tank contact material according to the present invention is that a perforated plate that can be folded into a folding screen is provided, and the perforated plates are arranged side by side in the thickness direction. A connecting member that engages in a freely connectable manner is attached to each of the mountain portions of the perforated plate.

[0005]

[Action]

 Since the septic tank contact material according to the present invention is a perforated plate that can be folded in a folding screen shape, it can be folded into a compact state as needed, but the adjacent parts can be connected to each other in a freely connectable manner. Since the connecting members are attached to the respective peaks of the perforated plate, it is possible to easily assemble them into a honeycomb shape having a large surface area simply by connecting the connecting members with the perforated plates arranged side by side in the thickness direction. it can.

[0006]

[Effect of device]

 Therefore, during storage or transportation, if space is allowed, the perforated plates can be flattened and stacked closely, and if sufficient space is not available, they can be folded and compacted. It can also be handled at. For example, since the perforated plate can be folded and handled in a compact state even when assembled, it is easy to put it in the tank even from a narrow inlet, and moreover, simply by connecting the connecting members, it is easy to form a honeycomb shape with a large surface area. Can be assembled. In other words, it was possible to provide a septic tank contact material that can be handled in a compact state as necessary and that can be easily assembled and used in a state where the contact efficiency with the water to be treated is good.

[0007]

【Example】

 Examples of the septic tank contact material according to the present invention will be described below. As shown in FIG. 1, the net plates 1 which are perforated plates made of plastic material and injection-molded into a folding screen shape are arranged side by side in the thickness direction as shown in FIG. A connecting member 2 for engaging the plates 1 with each other in a freely connectable manner is attached to each of the ridges of the net plate 1 to form a septic tank contact member.

As shown in (a) of FIG. 3, the connecting member 2 is formed in such a manner that one side is formed into a convex portion and the other side is sandwiched therebetween. For example, as shown in (b) in FIG. Different configurations may be adopted such that the convex portion is fitted into the concave portion and held as shown in FIG. With a plurality of the above-mentioned septic tank contact materials arranged side by side in the thickness direction, the net plates 1 adjacent to each other can be easily connected and engaged via the connecting member 2, and as shown in FIG. It can be assembled and used in a honeycomb shape with good contact efficiency.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
