摘要:

以环境水体中21种典型内分泌干扰物(EDCs)为目标物,对其在某城市污水处理厂厌氧-缺氧-好氧与MBR的组合工艺(A2/O-MBR)中的迁移和归趋进行了长期研究。结果表明,该工艺对21种EDCs有很强的去除能力。EDCs在A2/O-MBR工艺中泥水两相的迁移行为用泥水分配系数(Kd)来表示,得到的较高的泥水分配系数表明污泥对EDCs有一定的吸附作用,水相中大部分EDCs是通过污泥吸附来去除。

关键词: 内分泌干扰物质, 雌激素活性, A2/O-MBR, 迁移行为

Abstract:

Taking 21 kinds of typical endocrine disrupting compounds(EDCs) in environment water bodies as an research objective,a long term research on the transfer and fate of the combined process,anaerobic-anoxic-oxic membrane bioreactor(A2/O-MBR) of a municipal sewage treatment plant has been implemented. The results show that this process has strong removing capacity for the 21 kinds of EDCs. The sludge-water two phase transfer behavior of EDCs in A2/O-MBR process can be shown by sludge water distribution co-efficient. The higher sludge-water distribution co-efficient obtained indicates that sludge has certain adsorption effect on EDCs. In water phase,most EDCs are removed by sludge adsorption.

Key words: endocrine disrupting compounds(EDCs), estrogen activity, A2/O-MBR, transfer behavior
