【摘要】 在固定床中用β-环糊精处理苯酚废水,考察了β-环糊精的用量、固定床的密度以及pH值等影响因素。结果表明,苯酚废水浓度为100 mg/L时,β-环糊精处理废水能力为1.88 mL/g,废水处理的最佳pH=10.6,此时苯酚出水质量浓度可降至31.36 mg/L。密度较大的固定床处理效果优于密度较小的固定床。更多还原

【Abstract】 Wastewater containing phenol was treated by β-cyclodextrin(β-CD) in the stationary bed,and the dosage of β-CD,the density of stationary bed and pH value was investigated.Result showed that the treatment of β-CD was 1.88mL wastewater/g β-CD when phenol concentration was 100mg/L,and the optimal value of pH was 10.6 while the phenol concentration in the effluent liquid could be dropped to 31.36mg/L.The bigger density of stationary bed was prior to the smaller density of stationary bed.更多还原
