项目摘要

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.

竹木炭的过滤功能和吸附能力非常好，因为竹木炭是多孔的，并且竹木炭的特定表面大于木炭。因此，预计竹木炭可能会净化水，因为它可以使日常生命排水和河流的污染，令人反感的气味或杂质以及随着水污染的形式被粘在竹木炭上的微生物分解。然后，在这项研究中，建议将木炭是kagoshima县的本地工业，用于水处理。为此，使生物膜粘附在竹木炭的毛孔中，并检查了这种粘附微生物的基本纯化能力。此外，检查了各种条件下的治疗性能，目的是应用于实际的小规模河流。通过使用管状或批处理反应器检查了有关有机物（COD）的治疗特征（COD）。从这些实验结果中阐明了微生物固定竹木炭的可能性净化。在通过管状反应器进行流通操作中，当停留时间增加时，反应（去除）比增加了，提取比约为70显示了％。可以澄清的是，COD的降低率在很大程度上受批处理处理操作中温度的影响。
