摘要：进行了微型快速穿透（MCRB）实验与中小型、小型传统穿透实验方法的对照实验,结果表明,MCRB实验适用于模拟大型活性炭床的穿透情况,预测处理费用以及精选活性炭.MCRB实验加快了实验速度,避免了传统穿透实验中常见的问题.空床接触时间（EBCT）、活性炭粒径对MCRB实验有一定影响.使用粒径120～180目的活性炭,MCRB实验的压力一般小于3.03（105Pa. MCRB实验对2,4-二氯苯酚（2,4-DCP）和甲基叔丁基醚（MTBE）模拟废水的吸附处理获得合理的研究结果.
Micro column rapid breakthrough （MCRB） method for conducting dynamic carbon adsorption test was presented. The results of comparative breakthrough experiments showed that MCRB could be employed to simulate the breakthrough state of large activated carbon adsorbers, to estimate the cost of carbon treatment, and to select the best activated carbon. MCRB required 〈5% of time and sample volume that would be necessary using conventional test methods while avoiding most of the common operating difficulties/problems. The carbon particle size and the empty bed contact time （EBCT） affected MCRB performance. Using 120-180 mesh activated carbon, the pressure of MCRB test was less than 3.03-10SPa. MCRB results for treatment of 2,4-DCP and MTBE simulated wastewater were reasonable.
