摘　　要：实验研究了活性炭填充床脱除水中苯酚的吸附性能 ,探讨其饱和吸附填充床的再生方法。结果表明当平衡浓度变化范围为 0～ 0 .8kg m3 时 ,活性炭对水中苯酚的吸附能力达 2 30kg kg(吸附剂 ) ,吸附等温线符合Langmuir型 ;填充床的穿透曲线和穿透时间强烈依赖于实验条件 ,较高的进料浓度、较大的进料速度 ,以及较短的床层长度都将使填充床穿透较快 ;用热的NaOH稀溶液可再生被苯酚饱和的活性炭纤维填充床 ,再生效率达 90 %以上。The application of activated carbon for removal of phenol from water was studied. The adsorption capacity of activated carbon was favorable and the adsorption isotherm data can be represented by Langmuir isothermal for the range of phenol concentrations from 0 to 0.8 kg/m 3. The regeneration of activated carbon adsorbent saturated with phenol in fixed bed can be achieved by using sodium hydroxide solution for many times with 90% efficiency of regeneration.
