摘要: 随着甲基叔丁基醚（MTBE）作为汽油添加剂被持续大量使用，其已成为一种地下水中常见的有机污染物。本文通过纯净水、自来水和地下水中MTBE的平衡吸附容量和微型快速穿透实验（MCRB），比较了5种不同种类活性炭对MTBE的吸附性能。结果显示，苯酚值可准确预测活性炭样品对MTBE的平衡吸附容量大小次序，而丹宁酸值则可大致估计活性炭在实际处理应用时的吸附速度和吸附容量利用率。水样中共存的有机成分降低了活性炭对纯净水中MTBE的吸附容量，在背景TOC较低的去离子水中，活性炭对于MTBE的吸附性能反而比在地下水中降低得更多。穿透实验数据显示双柱串联的处理方式是高效应用活性炭吸附水中MTBE的优选工艺。使用环境友好的竹质活性炭去除地下水中MTBE具有良好的可行性和较高的性价比。

Abstract: Because of the increasing consumption of methyl-tert-butyl ether (MTBE) as a major gasoline additive， it has become a common groundwater contaminant. Many series of batch adsorption equilibrium capacity experiments and continuous flow breakthrough experiments， employing the efficient micro column rapid breakthrough (MCRB) method， were conducted to compare effectiveness of 5 granular activated carbons(GACs) in removing MTBE in pure water， tap water and groundwater. The carbons’ MTBE capacities were in the same order as their phenol numbers. The micro pore rich coconut GAC exhibited higher capacities than others； however， its capacity utilization rate was the lowest consistent with its lowest tannic acid number. The GACs’ capacities for MTBE were notably reduced by the naturally occurring organic compounds present in the sample solutions； the reduction was more notable for MTBE in tap water than in the higher TOC well water sample. The breakthrough data confirmed the GAC’s relative capacities for MTBE and that two serial adsorbers treatment as the most cost effective process scheme to produce a high quality effluent. The study has established the feasibility of employing the environmental friendly bamboo GAC， as the most cost effective type of GAC， for removing MTBE from contaminated groundwater.
