摘　　要：研究了H103型大孔吸附树脂对促进剂NS生产废水处理的工艺过程,探讨其吸附-脱附的最佳工艺条件,脱附液再经蒸馏回收叔丁胺。实验结果表明:H103型大孔吸附树脂对促进剂NS生产废水有良好的吸附-脱附效果。经H103型大孔吸附树脂吸附处理后,促进剂NS生产废水中COD去除率达97%以上,达到国家排放标准。对达到泄露点的树脂用甲醇进行脱附,考察了脱附的最佳工艺条件,树脂的脱附率达96%以上,叔丁胺回收率达95%以上。证明该处理工艺可行。H103 type macroporous adsorption resin is studied in accelerator NS production wastewater treatment process. The optimum process conditions of adsorption-stripping,stripping liquid and recycling tert-butylamine through distillation is explored. The experimental results show that H103 type macroporous adsorption resin has good adsorption stripping effect on accelerator NS production wastewater. After adsorption treatment with H103 type macroporous adsorption resin,the removal rate of COD in accelerator NS production wastewater can achieve above 97%,which meets the national discharge standard. To achieve leak point for stripping with methanol,the optimum process conditions of stripping is also studied. Under the optimal condition,the stripping rate of the resin is more than 96% and the recovery rate of tert-butylamine is more than 95%,which proves the feasibility of the treatment process.
