Therefore, the technique of culturing the above three kinds of fungi by pure culture is not adopted in this example.

The three fungi cultured as described above are dried until the water content is reduced to about 20%, and stored in the bag 4 together with rice bran or bran. As a material of the bag body 4, a non-woven fabric of chemical fiber, linen cloth, cotton cloth, or the like is used. However, since the cotton cloth is eroded by the above-mentioned fungi, it is necessary to prepare the bag 4 in consideration of this.

As a method for preventing water pollution using the block 1 having the above configuration, as shown in FIGS. 3 and 4, a plurality of locations on the river 10 serve as weirs. A plurality of the blocks 1 are arranged in a row (two rows in the illustrated example) in the width direction of the river 10. In this case, as shown in FIG.
Is preferably covered with a lid 5 that can be opened and closed.

When a plurality of blocks 1 are installed in the river 10 as described above, water is blocked by the aggregate of the blocks 1 arranged in a row, and sludge accumulates or floats in the region X on the upstream side. It will be in a state of having done. At this time, the specific fungi that escaped from the bag 4 from the inside of the block 1 passed through the porous portion, and as shown by the arrow a, the river 1
0 is discharged toward the area X.

As a result, the specific fungus absorbs energy from the organic matter in the sludge accumulated in the area X and, at the same time, decomposes the organic matter into carbon dioxide and water. Thereby, prevention of water pollution by the sludge of the river 10, that is, water purification treatment and deodorization treatment are quickly performed. In addition, since the above-mentioned water pollution can be prevented by using a specific fungus that is a specific fungus that is present in the natural world and that has been cultured under a natural environment, the natural fungi can be prevented without impairing the natural providence. While effectively harmonizing with
Quick processing will be performed. In addition, the specific fungus which has completed the decomposition of the organic matter becomes a feed for protozoa.

When the remaining amount of the specific fungus in the bag 4 of the block 1 becomes small, the lid 5 shown in FIG. 3 is removed, and the bag 4 containing the new specific fungus is removed. Exchange. As a result, the specific fungi are always present in the area X of the river 10 where sludge accumulates, and continue to decompose organic substances that cause water pollution. Therefore, purification and deodorization of the river 10 are always performed. This will be done promptly and contribute to national land conservation.

It is to be noted that a part of the specific fungi may be discharged from the block 1 to the downstream side of the river 10, but even in this case, it is useful for preventing water pollution on the downstream side. become.

The most preferable location of the block 1 in the river 10 is near the junction where the branch merges with the main stream, particularly at a predetermined location of the tributary near the junction.

On the other hand, the shape of the block 1 does not need to be a single cylindrical shape as in the above example.
As shown in FIG. 7, a plurality of half columnar bodies are connected and integrated at one side as shown in FIG. 5, a plurality of columnar bodies are connected and integrated at a central portion as shown in FIG. 6, and as shown in FIG. It may be a rectangular shape or the like. Further, it may be a tetrapot-shaped one installed on the shore, a river shore, a lake shore, or the like, or another wave-dissipating block-shaped one.

Further, as shown in FIG. 8, the block 1 may be formed as a pseudo tree whose appearance resembles a tree. In this case, it is preferable that the surface of the block 1 is in an unfired state. Then, as shown in FIG.
A plurality of the above blocks 1 are installed along the periphery of one pool. By doing so, the appearance of the surroundings of the pond 11 is improved, and water pollution is prevented in the same manner as described above. In particular, the effects of a pond existing in a Japanese garden become more remarkable.

In addition to the above, other modes of use may be those shown in FIGS. 9 and 10. That is, various pipes 12a, 1
A casing 13 is disposed at a position where 2b and 12c intersect, and a block 1 composed of a rectangular frame in a plan view as shown in FIG. The material and the like of the block 1 are the same as those described above. Then, fungus storage recesses 3 are formed at a plurality of locations of the block 1, and the bag 4 containing the specific fungus is held in each of the fungus storage recesses 3.

With such a configuration, the organic matter causing water pollution in the wastewater flowing from the pipe into the sewage is decomposed in the same manner as described above, and the sewage purification and deodorization treatment are rapidly performed.

Further, in addition to this, for example, a block 1 having the same basic configuration as that shown in FIGS. 9 and 10 is employed in a water pool part in the middle of the gutter or at the downstream end of the gutter. Is possible.

Further, the shape of the block 1 can be set according to each installation location, for example, it can be installed on a beach or a lake shore.

In the above embodiment, the fungus accommodating space is formed by forming a fungus accommodating recess having an open upper end in the main body of the block 1 as a fungal accommodating space. An input port for inputting the bag 4 and a lid for opening and closing the input port may be provided, and this input port may be connected to a fungus storage chamber formed inside the block 1.

Further, ignoring the ease of replacement,
The specific fungus may be stored and held directly in the fungus storage space without storing the specific fungus in the bag 4.

In the above embodiment, the main body of the block 1 is formed of a porous body (multi-porous body). However, other structures, for example, specific fungi may escape from the fungus storage recess 3. It may be one in which one possible through hole is formed. In any case, any structure may be used as long as the block 1 has a water-permeability or water-permeability function and can discharge specific fungi through the water-permeable portion.
