以水体中经常暴露的5种微量药物污染物:酰胺咪嗪(CBZ)、酮洛芬(KEP)、萘普生(NAP)、双氯芬酸(DCF)和扑热息痛(ACE)为研究对象,考察了反渗透(RO)、纳滤(NF)、膜蒸馏(MD)3种膜分离技术对5种目标药物的去除效果.试验结果表明:RO与MD两种膜分离技术对5种目标药物均能高效地去除,其中MD工艺出水中5种目标药物均未检出；RO工艺出水中,CBZ、KEP、NAP和DCF 4种药物也未检出,基本实现了完全去除,ACE的去除率略低,但也达到了96.5％；相对而言,NF工艺对5种目标药物的去除效果稍差,其对CBZ、KEP、NAP、DCF和ACE的去除率分别为60.5％±0.5％、82.3％±0.7％、84.2％±0.4％、83.5％±1％、41.1％±0.2％.
