摘要：

采用商业正渗透膜对废水中的3种不同抗生素（甲氧苄啶、四环素和磺胺甲噁唑）进行截留。研究了不同汲取液浓度、种类、共存污染物、pH值对3种抗生素的截留效果的影响。结果表明，提高汲取液浓度可以增加正渗透膜水通量，但也增加了溶质返混通量；由于3种抗生素的带电电荷和结构不同，与膜的表面作用也不同，TMP截留率>TC截留率>SMZ截留率，不同的抗生素的主导截留机制不同；共存污染物腐殖酸和牛血清白蛋白会促进抗生素的截留，且在碱性条件下抗生素的截留率会进一步升高。这些实验结果可为FO应用于抗生素废水的处理提供参数。

Three antibiotics with different charges,trimethoprim, tetracycline, and sulfamethoxazole were used to be rejected in waste water by a commercial forward osmosis membrane. The effects of different types of draw solution onthebasic properties of the forward osmosis membranewere studied. In addition, the effects of draw solution, organic contaminantsand different environmental pH on the rejection of three antibiotics under optimal conditions were also explored. The results showed that increasing the concentration of draw solution increased the water flux of the forward osmosis membrane and the reverse solution flux. Attributed to three kinds of antibiotics with different electric charge, they have different effects on the membrane. The rejection rate is ranked as TMP>TC>SMZ.In the presence of organic pollutants, alkaline condition will increase the rejection rate of the three antibiotics. These resultscan provide parameters for the treatment of antibiotic wastewater by a FO process.
