As shown in FIG. 3, a degrading enzyme 8 such as amylase is contained in the paper tube 2 together with the bacteria 6 and the nutrient 7. The decomposing enzyme 8 reacts with the organic solid to decompose it into fibers, and the bacteria 6 take in this and further promote the decomposition.

Therefore, the bacteria 6, the nutrient 7 and the decomposing enzyme 8 act synergistically to promote the decomposition of the paper tube 2 itself and improve the function of the wastewater treatment facility.

The above bacteria 6, nutrients 7, decomposing enzymes 8
2 is interposed between the windings of the paper core base paper 4 as shown in FIGS. That is, the core paper core 2 is usually formed of the paper core inner layer 2.
a and the paper tube outer layer 2b are formed in a hollow cylindrical shape with an adhesive 5 interposed therebetween, and the bacteria 6 and the like are mixed into the adhesive 5 to form the paper tube inner layer 2a and the paper tube outer layer 2b. The structure is such that the bacteria 6 and the like are held in the paper tube 2 while achieving adhesion. Thereby, the bacteria 6 and the like can be uniformly and reliably kept in the paper tube 2.

The adhesive 5 is applied between the inner layer 2a and the outer layer 2b in a linear or dotted manner, and the bacterium 6 or the like is placed in a space between the inner layer 2a and the outer layer 2b where the adhesive 5 is not applied. It may be configured to be retained (enclosed).

Each of the above embodiments shows a specific example in which the paper tube 2 is spirally wound in multiple layers and bacteria 6 and the like are held between the windings.

As means for supporting the bacteria 6 and the like on the paper tube 2, the bacteria 6 and the like are contained in the paper tube base paper 4 as shown in FIG.

As an example, when the paper tube base paper 4 is made, the bacteria 6 and the like are mixed therein, and the paper tube base paper 4 is used to form the paper tube 2.

Alternatively, although not shown, a plurality of holes or grooves are provided in the base paper 4 forming the inner core layer 2a or the outer core layer 2b, that is, holes or grooves are formed in the inner core layer 2a or outer layer 2b or both layers 2a and 2b. The bacteria 6 and the like are held in the holes or grooves, and the holes or grooves are sealed with the toilet paper 3 or the like.

The adhesive 5 is desirably a water-soluble polymer adhesive such as liquid carboxymethyl cellulose (hereinafter referred to as liquid CMC). Thus, the adhesive 5 does not become a factor inhibiting the dissociation of the paper tube base paper 4, and the decomposition of the paper tube 2 by the action of the bacteria 6 and the like can be expected effectively.

Further, as another example, the present invention does not allow bacteria 6 to be held in the core paper tube 2 of the toilet paper roll 1,
