| Outline of Final Research Achievements |
Some transformed products of pharmaceuticals (TPs) often have adverse effects on aquatic ecosystem and human health. In this research, the actual TPs concentrations in the reclaimed wastewater of rural sewerage and in the water in the paddy field applied with the reclaimed wastewater were clarified. We found that it is very effective for depression of the TPs concentration to keep the high bacterial concentration in the treatment tanks in rural sewerage, the long water retention time in the paddy and so on, because the biodegradation and photodegradation are enhanced in the conditions. These findings will contribute to the high safety of the rural sewerage reclaimed water for aquatic ecosystem and human health and the reliability of the water purification function of the paddy irrigated with the reclaimed water.
