摘要

通过填料塔动态吸附实验，考察了填料高度、MB初始浓度和流速对动态吸附曲线的影响。结果表明:老化垃圾能有效吸附水中的MB，随着填料高度的增加，曲线上的突破点向右移动，突破时间延长;而随着流量和MB初始浓度的增加，曲线的突破点向左移动，突破时间缩短。初始阶段的吸附过程符合Adams-Bohart模型。BDST模型可以很好地描述吸附剂高度对去除MB的影响。

Study on dynamic adsorption of methylene blue by aged-refuse

The performance of dynamic adsorption and the effects of height of filler, MB initial concentration and flow rate on the breakthrough curves were investigated by the dynamic adsorption experiment of the filler column. The results showed: Aged-refuse can effectively adsorb MB in the water, with the increase of filler height, the breakthrough point in the curve move toward the right and the breakthrough time is prolonged. Whereas, with the increase of flow rate and MB initial concentration, the breakthrough point of the curve shifts toward the left and the breakthrough time is shortened. The adsorption process in the initial phase conforms to Adams-Bohart model. The effect of sorbent height on removal MB can be well described by BDST model.
