摘要

研究了树脂吸附法处理苯甲醇生产废水，考察了树脂吸附-脱附的影响因素，并优化了工艺参数。结果表明，超高交联大孔吸附树脂JX-101对苯甲醇具有良好的吸附-脱附性能，废水经固定床吸附工艺处理后，苯甲醇浓度从14000 mg·L-1降至25 mg·L-1，COD从34000 mg·L-1降至100 mg·L-1以下，苯甲醇和COD去除率均超过99%，出水水质达到国家一级排放标准，同时还可以从废水中回收得到纯度高达85%的苯甲醇。该技术工艺操作简便，运行稳定可靠，为苯甲醇生产废水的治理和资源化提供了实验依据。

Abstract

An adsorption process to treat the wastewater from benzyl alcohol production with hyper-crosslinked macropore resin was studied.The factors

including pH

temperature

flow rate

desorption reagent

etc.that influenced the adsorption-desorption process were investigated.Based on the investigation

the process parameters for the treatment were optimized.The results showed the hyper-crosslinked macropore resin JX-101 exhibited excellent adsorption-desorption performance for benzyl alcohol.Through the fixed-bed adsorption process under optimal conditions

the concentration of benzyl alcohol in the wastewater was reduced from 14000 mg·L-1 to 25 mg·L-1 and COD was reduced from 34000 mg·L-1 to less than 100 mg·L-1.The removal rate of benzyl alcohol and COD was over 99%，and the effluent quality met National Discharge StandardⅠ.Furthermore

benzyl alcohol in the wastewater could be recovered

with purity of 85%.The process is convenient and could be steadily run

which provides the experimental basis for the treatment and resource reuse of benzyl alcohol production wastewater.
