The occurrence and seasonal variation of 50 pharmaceuticals and personal care products (PPCPs) in a wastewater treatment plant (WWTP) in Xiamen, China was investigated over a period of one year. Among the targets, 39 PPCPs were detected in the influent. The highest concentration was observed for acetaminophen, with the average concentration in the influent of 2963.5ng/L. The seasonal variation of PPCPs in the influent was observed. For most pharmaceuticals, highest concentrations were in March 2013, followed by December 2012, while the concentrations were lower in August 2012 and May 2013. Among the detected PPCPs, 14 targets could be removed more than 50% in the WWTP. The activated sludge treatment process contributed to most of PPCP removal, while the adsorption to the particles in the primary treatment and the transformation under UV radiation in the disinfection treatment also contributed to the PPCP removal. Among the detected PPCPs in the influent, 36 PPCPs could be detected in the final effluent of the WWTP. Significantly higher concentrations of PPCPs were observed in effluent samples collected in March 2013 compared to other seasons, suggesting higher concentrations of PPCPs could be discharged into the surrounding seawater during this period.
在中国厦门的一家污水处理厂（WWTP）中，研究了 50 种药物和个人护理产品（PPCP）在一年内的出现和季节性变化。在所研究的目标中，进水口检测到 39 种 PPCP。在进水口中，浓度最高的是扑热息痛，平均浓度为 2963.5ng/L。进水口中 PPCP 的季节性变化也被观察到。对于大多数药物，浓度最高的是 2013 年 3 月，其次是 2012 年 12 月，而 2012 年 8 月和 2013 年 5 月的浓度较低。在所检测到的 PPCP 中，有 14 种目标在 WWTP 中可以去除超过 50%。活性污泥处理过程对 PPCP 的去除贡献最大，而初级处理中颗粒的吸附和消毒处理中紫外线辐射下的转化也有助于 PPCP 的去除。在所检测到的进水口 PPCP 中，有 36 种 PPCP 可以在 WWTP 的最终出水中检测到。与其他季节相比，在 2013 年 3 月采集的出水样本中观察到 PPCP 的浓度明显更高，这表明在此期间，更多的 PPCP 可能被排放到周围的海水中。
