摘要 近年来,内分泌干扰物因损坏生物的内分泌系统而引起人们的广泛关注。其中甾体雌激素(SEs)由于具有极强的内分泌干扰能力,在极其微量的情况下便可对生态系统及人和动物的健康产生不可预测的危害,而城市污水处理厂排放的剩余污泥是环境中该类化合物的重要来源。文章结合最近国内外的研究成果,指出了研究内分泌干扰物在城市污水处理厂剩余污泥处理过程中归趋的重要性,重点总结了有关雌酮、17β-雌二醇、雌三醇、17α-乙炔雌二醇等甾体雌激素在城市污水处理厂污泥处理过程中归趋的主要研究进展,包括4种甾体雌激素的基本理化性质、城市污泥处理系统各处理单元中雌激素的背景含量、主要污泥处理过程对雌激素的去除效果及其机制等,并展望了今后该方面的研究前景、热点和趋势。 Steroid estrogens(SEs) belong to the EDCs,whose risks to human and wildlife have greatly drawn concerns over the world.This paper reviews the research reports regarding EDCs including SEs,E1,E2 and E3 in excess sludge of municipal WWTPs,discussing the bio-solids in terms of especially SEs' fate in the environment in process of treatment and disposal of the sludge,focusing on removing efficiencies and mechanisms of ESs.
