水环境中典型抗抑郁药物的分布与去除现状

抗抑郁药物是一类具有生物毒性的新型环境污染物,近年来在水环境中频繁检出,已引起水处理界的广泛关注。介绍了典型抗抑郁药物的来源及分布现状,并以检出频率较高的西酞普兰和文拉法辛为例,综述了其在污水处理厂中的去除现状,以及高级氧化技术对其的降解效果。由于我国对水环境中的抗抑郁类药物的研究尚处于起步阶段,因此在今后的研究中有必要关注典型抗抑郁药物在污水处理过程中的降解机制,探究污水成分对降解过程的影响。

Research status of distribution and removal of typical antidepressants in the aquatic environment

Antidepressant pharmaceuticals, as a group of new emerging contaminants with biological toxicity, have been frequently detected in the aqueous environment, which caused wide concerns. The sources and distribution of the typical antidepressants were introduced in this paper. The frequently-detected citalopram and venlafaxine were selected as representatives. Their removal in wastewater treatment plants was summarized. The degradation efficiencies by advanced oxidation technology were also discussed. Since the research of antidepressant pharmaceuticals in the aquatic environment is still at the early stage in China, it is necessary to study the degradation mechanism of typical antidepressant pharmaceuticals in the sewage treatment process and explore the impact of wastewater composition on the degradation process.
