Abstract
Fifteen kinds of pharmaceuticals were measured for the influent and the reclaimed wastewater in the actual five plants of rural sewerage. While all kinds of pharmaceuticals were detected in all water samples, almost all of the concentrations in the reclaimed wastewater were lower than the influent wastewater in almost all plants employing activated sludge process. These results indicate the pharmaceuticals removal function in the plants. While the tendency between influent and reclaimed waster was also observed for the biofilm process plant, it was lesser certain than activated sludge plants. Except Ketoprofen (nonsteroidal anti-inflammatory drug), all of the pharmaceuticals concentrations in the reclaimed wastewater was estimated as the no risk for aquatic ecosystem. From the results, the further researches on Ketoprofen in the biofilm plants would be significance.
