The abundance of pharmaceuticals found in natural water sources has increased as their applications and production has increased. In the environment, pharmaceuticals have the potential to be toxic, increase microbial resistance, and yield other unforeseen environmental adverse effects. Effluents of municipal sewage treatment plants represent a major pollution source of pharmaceuticals in the environment. Therefore, it is of utmost importance to study different advanced treatment methods to further remove pharmaceuticals in sewage effluent. In collaboration with Dr. Zhimin Qiang, an expert in wastewater research at the Chinese Academy of Sciences, this study will determine the most applicable method to remove typical pharmaceuticals from sewage effluent by advanced treatment processes. The toxicity, microbial resistance, and unforeseen adverse effects in the environment, induced by pharmaceuticals, necessitate a comprehensive study of abatement, degradation pathways, and toxicity changes of each target pollutant during advanced oxidation processes (AOPs). The selected AOPs include three O3-based and UV-based (e.g. O3/H2O2, UV/O3, and UV/H2O2) technologies, which have great potentials to effectively remove pharmaceuticals from sewage effluent. Six frequently detected pharmaceuticals in sewage effluent, including sulfadiazine (SDZ), sulfamethoxazole (SMX), trimethoprim (TMP), metoprolol (MET), roxithromycin (ROX), and caffeine (CAF), will be selected for this study. The abatement of these pharmaceuticals by the AOPs will be studied, along with their degradation byproducts identified by liquid chromatography time-of-flight mass spectrometry (LC/Q-TOF-MS) to propose degradation pathways. In addition, this project will evaluate the pollutant removal efficiency, energy consumption, and operation factors of the different AOPs, to determine the most applicable method. This NSF EAPSI award is funded in collaboration with the Chinese Ministry of Science and Technology.

天然水源中的药物含量随着其应用和生产的增加而增加。在环境中，药物有可能是有毒的，增加微生物的耐药性，并产生其他不可预见的环境不利影响。城市污水处理厂的废水是环境中药物的主要污染源。因此，研究不同的深度处理方法以进一步去除污水中的药物是至关重要的。与中国科学院废水研究专家Zhimin Qiang博士合作，这项研究将确定通过深度处理工艺从污水中去除典型药物的最适用方法。由于药物的毒性、微生物的耐药性以及对环境的不可预见的不良影响，有必要对高级氧化工艺（AOPs）过程中各目标污染物的减排、降解途径和毒性变化进行综合研究。所选的高级氧化工艺包括O3/H2 O2、UV/O3和UV/H2 O2等3种技术，它们在有效去除污水中的药物方面具有很大的潜力。本研究选取了磺胺嘧啶（SDZ）、磺胺甲恶唑（SMX）、甲氧苄啶（TMP）、美托洛尔（MET）、罗红霉素（ROX）和咖啡因（CAF）等六种常见的污水处理药物。将研究这些药物通过AOP的减少，沿着通过液相色谱飞行时间质谱法（LC/Q-TOF-MS）鉴定其降解副产物，以提出降解途径。此外，本项目将评估不同高级氧化程序的污染物去除效率、能耗和运行因素，以确定最适用的方法。NSF EAPSI奖是与中国科技部合作资助的。
