By burning bamboo to form bamboo charcoal 5, porous portions 5a, 5a, ···, 5a having a plurality of gaps are formed. The porous portion 5a functions as a breeding medium for filamentous fungi and bacteria.

Also, by using the periphery of the bamboo nodes, the protrusions 5 protruding from the outer periphery of the nodes prevent slipping from the block body 2 (concrete) and have the effect of making it difficult to separate. 5 is hard to fall off from the block body 2.

'Also, the section 6 inside the bamboo is penetrated in advance. The hole to be penetrated (hereinafter, referred to as “through hole 5 c”) is formed smaller than the diameter of the inner frame of the bamboo charcoal 5. This section 6 functions as a throttle to restrict water flow and generate turbulence.

The filter 8 is provided to prevent dust and the like flowing from the upstream side from flowing into the flow path. This prevents the flow path from being clogged by dust or the like contained in water or the like. The filter 8 is provided at the end of the block body 2 so as to be detachable, and is replaced periodically. Further, the filters 8 may be provided at both ends of the block body 2.

When the purification block 10 is actually placed on a river or the like, the block main bodies 2 are stacked in a plurality of stages or placed side by side.

FIG. 2 is an example of installation of a purification block in the present embodiment. In FIG. 2, parts that are the same as in FIG. 1 are given the same reference numerals, and descriptions thereof are omitted. As shown in the figure, purification blocks 10, 10,..., 10 are installed in rivers and the like. The purification blocks 10 are installed at predetermined intervals along the flow of the river 15.
