摘要:

采用树脂吸附法治理2-羟基-3-萘酸(2,3酸)废水。研究了不同树脂吸附剂、脱附溶剂以及吸附倍数、停留时间对处理效果的影响。试验结果表明:用DF-211树脂吸附剂在pH为2,流速为4~8BV/h条件下,吸附倍数达到80~120BV,用溶剂E脱附后,树脂可反复使用。

关键词: 2-羟基-3-萘酸, 树脂吸附法, 水处理

Abstract:

The treatment of2-hydroxy-3-naphthalene carboxylic acid wastewater by resin adsorption process is introduced.The influences of different resin adsorbent,different desorption solvent,adsorption folds and staying time on the efficiency of the treatment of wastewater by resin adsorption process have been studied respectively.The results show that the optimum conditions are as follows :the flow rate with4~8BV/h at pH2by DF-211resin adsorbent,the adsorption folds can reach80~120BV and the solvent E can be used repeatedly.

Key words: hydroxy-3-naphthalene, carboxylic acid resin adsorption, water treatment
