采用稻壳灰吸附柱吸附含铅废水，通过吸附量的计算及穿透曲线的绘制探讨了不同质量浓度共存锌离子对吸附过程的影响。并通过Thomas模型及Yoon－Nelson模型拟合，分析共存锌离子对吸附过程的影响。结果表明，共存锌离子质量浓度越大，稻壳灰对铅离子的吸附量越低，吸附到达平衡的时间越短，同时锌离子占据了部分吸附位点，并没有改变稻壳灰与铅离子的结合方式。

This paper adopted the rice husk ash ( RHA ) to dynamic adsorbed Pb in the wastewater.The adsorption capacities were calculated and the breakthrough curves were drew to analyze the effect of Zn ( II) on the removal of Pb.In addition,Thomas Model and Yoon-Nelson Model were chosed to describe the adsorption process.It was showed that the high-er concentration of Zn ( II) existed,the lower adsorption capacity RHA had, and the break-through time occurred earlier.However,the co-existing Zn ( II) did not change the combi-nation process of Pb though it decreased the adsorption capacity of rice husk ash.
