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.
