摘　　要：以城市污水处理厂剩余污泥作为原料,采用化学活化法(Zn Cl2作为活化剂)和微波辐照制备污泥活性炭,研究其对亚甲基蓝的吸附效果和吸附等温过程。结果表明,当p H值3、投加量1 g/L、吸附时间120 min和温度35℃时,亚甲基蓝的吸附率都在98%以上。等温吸附过程很好的符合Langmuir模型。The excess sludge of sewage treatment plant chosen as raw material,sludge activated carbon was prepared by the chemical activation method( Zn Cl2 as an activator) and microwave radiation. Methylene blue( MB) was used to simulate dyeing water. The removal ratio of MB and the isotherms adsorption process were investigated. The results showed that the removal ration was above 98% under the experimental conditions( p H value 3,dosage of 1 g / L,time of 120 min and temperature of 35 ℃). The adsorption process could be described by Langmuir formula.
