SEs在水体及水处理工艺中污染状况的研究与展望

摘要

In this paper, the occurrence and effects of Steroid Estrogens (SEs) in aquatic environment in different countries and places and distribution in water treatment process were reviewed systematically and comprehensively.The results showed that SEs were detected in aquatic environment around the world with concentration normally from pg/L to ng/L, and the removal effect of them was not satisfying.SEs in aquatic environment mainly originate from human and animal's excreta, and will be transformed in aquatic environment.At present, it is urgent to establish specific water quality safety evaluation method, and carry out toxicity reduction engineering research under SEs elimination condition.%综述了甾体雌激素(SEs)对不同国家和地区的水环境所造成的污染及其在水处理工艺中的分布.结果表明,世界各地水环境中都检出了SEs污染物,其浓度一般达到pg/L～ng/L水平,而水处理工艺对其处理效果不佳.水环境中SEs主要来源于人和动物的排泄物等,在水环境中会发生进一步转化.目前亟需建立针对性的水质安全评价方法,进行SEs去除务件下的毒性削减技术研究.
