项目摘要

In recent years, as for the effect of water pollution on environment, there are various problems, such as its effects on agriculture as well as human body. The contamination of river water is mainly due to the decomposed and colored water. The purpose of this research is to purify water quality using the characteristics of bamboo charcoal, special product of Kagoshima Prefecture and pumice stones which are distributed in South Kyushu.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.The influence of the operation conditions in pipe-type circulation formula is considered by adhering microbes to the surface of bamboo charcoal and pumice stones in the shape of a film.

近年来，至于水污染对环境的影响，存在各种问题，例如它对农业和人体的影响。河水的污染主要是由于分解和彩色水。这项研究的目的是使用竹木炭的特征，kagoshima县的特殊产品和浮石石净化水质，这些产品分布在南九州。竹木炭的过滤功能和吸附能力非常好，因为竹木炭是竹木炭的多孔和比表面大于木炭。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。出于目的，生物膜是在竹木炭的孔中粘附的，并检查了这种粘附微生物的基本纯化能力。通过将微生物粘附到表面上，考虑了操作条件在管道型循环公式中的影响薄膜形状的竹木炭和浮石石。
