| Research Abstract |
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.
