纳滤膜技术去除水中内分泌干扰物

Removal of Endocrine Disrupting Chemicals in Water by Means of Nanofiltration Membrane Technological Process

传统的污水处理工艺对内分泌干扰物（EDCs）的去除效果不稳定，而且不能彻底去除水中EDCs，使之达到产生危害的阈值浓度以下。大部分EDCs是分子量在200，500Da之间的有机物，这些污染物大多数是疏水性分子，纳滤膜对小分子有机物良好的筛分作用和吸附作用，运用纳滤技术去除EDCs是一种切实可行和安全有效的方法。

The removal efficiency of conventional sewage water treatment processes on EDCs is unstable and incomplete, which leaves the residual concentration of the pollutants below safe standard. Most EDCs are hydrophobic organic pollutants with relative molecular weight （MW） ranging from 200 to 500, which can be screened and adsorbed effectively. NF technology for EDCs removal is practical and safe.
