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，水污染对环境的影响存在多种问题，如对农业、对人体的影响等。河水的污染主要是由于河水的分解和有色。本研究的目的是利用鹿儿岛县特产竹炭和九州南部分布的浮石的特性来净化水质。竹炭的过滤功能和吸附能力非常好，因为竹炭是多孔的，而且竹炭的比表面积比木炭大。因此，竹炭可以吸附日常生活排水和河流中的污垢、恶臭或杂质，并且通过附着在竹炭上的微生物分解作为水污染的有机物质，因此预计可以通过竹炭净化水。因此，在本研究中，建议使用鹿儿岛县当地工业的竹炭进行水处理。为此，使生物膜粘附在竹炭的孔隙中，并检查该粘附微生物的基本净化能力。通过将微生物以膜状粘附在竹炭和浮石表面，考虑了管道式循环公式中操作条件的影响。
