• 摘要：内分泌干扰物作为一类新型污染物,由于其在环境水体中微量的浓度即可对野生动物产生内分泌干扰效应,因此引起了人们的广泛关注.本文以两类主要内分泌干扰物(即类固醇雌激素和酚类内分泌干扰物)作为研究对象,综述了它们在城市污水处理厂中的浓度水平以及相应的去除效率,并探讨了不同生物处理工艺、运行操作条件等对去除效率的影响.此外,通过分析内分泌干扰物在活性污泥上的吸附和生物降解特征,提出了其在活性污泥处理系统中可能的去除机制.

• Abstract：Endocrine disrupting chemicals (EDCs), as a class of emerging contaminants, have raised worldwide concern due to their potential disrupting effects on the endocrine system of wild animals even at trace levels in the aquatic environment. This paper reviews the occurrence and removal efficiency of two groups of typical EDCs (i.e., steroid estrogens and phenolic EDCs) in municipal sewage treatment plants, and particularly discusses the effects of different biological treatment processes as well as operational parameters on their removal efficiency. Further, through examining the adsorption and biodegradation characteristics of EDCs, the possible removal mechanisms of EDCs in the activated sludge process are proposed.
