类固醇雌激素在活性污泥系统中去除研究进展

Research progress of removal of steroid estrogen in activated sludge system

类固醇雌激素是内分泌干扰物的一种,具有较强的内分泌干扰性,是水环境中导致内分泌干扰效应的主要物质,对人类的健康存在潜在性危害.污水处理厂是天然水体中雌激素的重要来源之一,目前活性污泥处理工艺在污水处理设施中应用最为广泛.综述了类固醇雌激素的性质、来源及其在活性污泥系统中的去除效果和去除机制,并展望了该领域未来研究发展方向.

Steroid estrogen, with potent endocrine disruption, is one of the endocrine disrupting chemicals. It is the major material causing the endocrine disruption in aquatic environment, and has potential endangerment on human beings. The effluent from WWTP （waste water treatment plant） is considered to be the crucial source of estrogenicity in waterways, while the activated sludge system is widely used in the WWTP. This paper represents the nature and sources of steroid estrogen, and further reviews the removal efficiency and possible mechanisms, and finally prophesies the orientation of this research field.
