17β-雌二醇在水体中的分布水平及去除方法研究现状

17β-雌二醇(E2)是一种常见的天然雌激素,普遍存在于各类水体环境,在水环境分布水平已经达到干扰鱼类内分泌系统的水平,被认为是作用最强烈、最具潜在影响的环境内分泌干扰物之一。文章重点介绍了17β-雌二醇在水体环境中的分布水平及去除方法,指出由于传统的污水处理工艺和净水工艺无法将其完全去除,增加深度处理工序已经迫在眉睫。针对E2的特点,现有水处理工艺宜增加能够生成强氧化剂.OH的工序。

Distribution Level and Removal Methods of 17β-estradiol in Water Environment

17β-estradiol(E2)is a common natural estrogen,which widely exists in various types of water environment.As its distribution levels in water environment meet the criteria to interfere the endocrine systems of fish,it is known as one of environmental endocrine disruptors(EEDs) that have a strong and potential effect to the environment.The distribution level and removal methods of 17β-estradiol in water environment were discussed.Because the traditional sewage treatment technologies and water purification process cannot remove E2 completely,it is necessary to add an advanced treatment process to the traditional treatment process.According to features of E2,a process which can generate strong oxidizer ·OH should be added.
