| 摘 要： | 采用终端超滤工艺及膜静态吸附试验,对可溶性有机物(DOM)在超滤去除饮用水中内分泌干扰物双酚A(BPA)的影响方面进行研究。研究主要考察了腐殖酸作为DOM的替代物对超滤去除BPA的效果及膜吸附BPA的性能等方面的影响。结果表明,腐殖酸对超滤去除饮用水中双酚A没有显著影响。不同腐殖酸浓度下,初始浓度为400μg/L的BPA溶液的超滤去除率和吸附率分别为96%和68%左右。试验证实,在试验周期内吸附是大孔径超滤膜去除小分子BPA的主要作用。BPA在超滤膜面的静态吸附较好的遵循了Freundlich吸附等温线。水中BPA处于较高浓度水平时,高浓度的腐殖酸使得膜对BPA的静态吸附性能有所提高。

| Abstract: | Investigated in the paper are the effects of dissolved organic matters on the removal of bisphenol A(BPA) in drinking water by ultrafiltration membranes(UF) with dead-end stirred-cell filtration system and static adsorption device.The experiment is focused on the effects of humic acid as a substitute for DOM on BPA removal efficiency by ultrafiltration and adsorption efficiency of PES membranes.The results show that the influence of humic acid is minor in solution on BPA removal by UF.With the initial conce... |
