This study developed analytical methodology of fullerene nanoparticles in wastewater, investigated their fate in the activated sludge process and evaluated their adverse effects on water environment and wastewater treatment. Then, the fate of pharmaceuticals shifted to sewage sludge during sewage treatment was investigated in anaerobic digestion processes. Estimation methodology of influenza patient numbers was also studied from change in the concentrations of anti-influenza virus drugs detected in influent sewages in a sewage treatment plants. Finally, reduction levels of pharmaceuticals in treated sewage by ozonation, ultraviolet irradiation and advanced oxidation process were reviewed from literatures.

本研究开发了废水中富勒烯纳米粒子的分析方法，研究了它们在活性污泥过程中的归宿，并评估了它们对水环境和废水处理的不利影响。然后，在厌氧消化过程中研究了污水处理过程中转移到污水污泥中的药物的命运。还根据污水处理厂进水污水中检测到的抗流感病毒药物浓度的变化，研究了流感患者人数的估计方法。最后，从文献中对臭氧化、紫外线照射和高级氧化工艺处理污水中药物的降低水平进行了综述。
