The filtering function and the adsorption ability force of bamboo charcoal are excellent, because bamboo charcoal is porous and the specific surface of bamboo charcoal is bigger than that of charcoal. Therefore, it is expected that the water purification is possible by bamboo charcoal, since it adsorbs fouling, offensive odor or impurity of daily life drainage and rivers and the organic substances as water pollution are decomposed by the microorganism which is adhered to the bamboo charcoal.Then, in this study, it is proposed that bamboo charcoal which is local industry of Kagoshima Prefecture is used for water treatment. For the purpose, the biofilm was made to adhere in the pore of the bamboo charcoal, and the basic purification capacity of this adhesion microorganism was examined. In addition, the treatment performance under various conditions was examined for the purpose of applying to actual small-scale rivers. The treatment characteristics about organic matter (COD) were examined for the model waste water by using tubular or batch reactor. It was elucidated from these experimental results that water purification is possible with the microorganism fixed bamboo charcoal.In the flow-through operation by the tubular reactor, the reaction (removal) ratio increased when the residence time increased, and the extraction ratio of about 70% was shown. It was clarified that the diminution rate of COD was largely affected by the temperature in the batch processing operation.

由于竹炭的多孔性和比表面积比木炭大，所以竹炭的过滤功能和吸附能力都很好。因此，由于竹炭吸附生活排水和河流中的污垢、恶臭或杂质，并且附着在竹炭上的微生物分解作为水污染的有机物，因此可以期待竹炭能够净化水。本研究提出将鹿儿岛县的地方产业竹炭用于水处理。为此，将生物膜附着在竹炭的孔隙中，并检测该附着微生物的基本净化能力。此外，在各种条件下的处理性能进行了检查的目的，适用于实际的小规模河流。采用管式反应器和间歇式反应器对模拟废水进行了有机物（COD）的处理特性研究。从这些实验结果可以看出，利用微生物固定化竹炭进行水净化是可能的。在管式反应器的流通操作中，反应（去除）率随着停留时间的增加而增加，并且显示出约70%的提取率。结果表明，在间歇处理过程中，温度对COD的去除率有很大的影响。
