The types of activated carbon are roughly classified into powder and granules, and are classified into a gas activation method and a chemical activation method according to the activation method. At present, the gas activation method is mainly used. Granular activated carbon is further classified into crushed coal and shaped coal. Crushed coal is used to dry starting materials
It is carbonized, crushed and sized, and activated. In the case of molded coal, the starting material is dried and carbonized and pulverized. This is mixed with a binder, molded, dried and fired to activate.

くなる欠点を有している。As described above, conventional activated carbon is used in the form of powder or granules, and has advantages and disadvantages such as difficulty in processing management, cost and difficulty in disposal, and differs depending on the purpose of use. . Particularly, in the case of powder, handling such as pouring is extremely difficult, and at the time of disposal, there is a problem that black sludge containing deposited coal dust causes pollution. Further, in the case of the granular form, although the handling is easier than that of the powder, there is a problem that as the particle size increases, the life of filtration (the number of days until the odor leaks) decreases.
On the other hand, when the particle size is reduced, the filtration resistance (loss head) increases.

First, waste paper 2 is agitated while adding water to form a flocculent material, and wood chips 3 are mixed. Raw materials. Then, this is filled into a mold having a predetermined shape and compression molded. After drying the block-like product thus obtained, a firing step and an activation step are performed to form the activated carbon block 1 according to the present invention. The respective steps of drying, firing and activation can be performed in the same manner as in the prior art, and are not particularly limited. In short, waste paper 2 may be used as a starting material, such as a dispersion of cotton paper or slurry, or a mixture of these materials and ceramics such as wood chips 3 and sand. Anything should do.
