摘　　要：研究采用树脂吸附法处理硝化废水的效果,通过静态吸附实验,从14种树脂中筛选出国产大孔吸附树脂AB-8,在酸性条件下处理硝化废水效果较好,用于动态吸附实验,采用2BV·h-1,3BV·h-1,6BV·h-1等3种不同流速进行动态吸附实验。实验结果显示:硝基苯去除率为70%,硝基氯苯去除率为99%,CODCr去除率为43%,用工业乙醇作脱附剂,洗脱效果较好,树脂再生后可重复使用。The research adopts resin adsorption to process the nitration waste Water. By the static adsorption experiment, AB-8,a domestic macroporous resin, is screened from 14 kinds of resins, which has good effect to process the nitration waste water under the acidic condition. Then AB-8 is used in the dynamic adsorption experiment, with different flow speeds of 2 BV·h^-1, 3 BV·h^-1, 6 BV·h^-1. The result shows that the removal rates of nitrobenzene, chloronitrobenzene and COD are 70%,99% and 43% respectively. The industry ethanol is used as the elution to achieve the reuse of resin effectively.
