抄録

In the preparation process of fatty acid methyl ester (FAME) as biodiesel fuel by the alkaline catalyst method, FAME washed wastewater containing glycerin with high concentration is drained. Charcoal made from bamboo has been used for biological media in treatment for the wastewater. First, the coagulation-sedimentation method was applied for the wastewater, proceeded with treating with aerobic microorganisms with the charcoal. The total organic carbon (TOC) concentration and total nitrogen (T-N) concentration decreased in the treated wastewater after the flow-typed column vessel, accompanied with the color change from yellow to transparent state. The adenosine tri-phosphate (ATP) concentration in the wastewater treated with the charcoal increases after biological treatment compared with in the wastewater without charcoal. Many kinds of microorganisms on the surface of the charcoal picked up from the column were observed with SEM photography. The quality improvement of the wastewater was come from increase of microorganisms in the wastewater in the column and on the surface of the charcoal, because bamboo contains a lot of micro pores suitable for microorganisms medium.
