  • 摘要: 以城市污水处理厂的脱水污泥为原料,用ZnCl2活化法制备污泥活性炭,并研究其对水中酸性红G的吸附、脱附行为。选取活化剂浓度、固液比、活化温度及活化时间等因素,通过正交实验确定了最佳工艺,即ZnCl2浓度30%,固液比1:2,碳化温度500℃,碳化时间1.5 h。吸附实验结果表明,该污泥活性炭对水中酸性红G的吸附量随着温度升高而增加,在15、25和35℃条件下的最大吸附量分别为153.6、165.6和180.4 mg/g,且吸附等温线能较好用Langmuir方程进行模拟。酸性红G在污泥活性炭上的吸附动力学符合准二级反应动力学模型。污泥活性炭对酸性红G的吸附量随着溶液pH的增大而减小,污泥活性炭的最佳投加量为0.26 g/L。吸附饱和的污泥活性炭可通过碱处理和热处理方法进行脱附,脱附后的吸附剂对酸性红G仍具有很强吸附性能。
    Abstract: The dewatered sludge from a municipal wastewater treatment plant was used as raw material to produce activated carbon, and its adsorption and desorption behavior for acid scarlet G were also studied.The parameters such as the concentration of activated agent, the ratio of solid to liquid, the activation temperature and the time of activation for the preparation of sludge activated carbon were studied and the optimum preparation conditions determined by orthogonal experimental design were ZnCl2 concentration of 30%, the solid to liquid ratio of 1:2, activation temperature of 500℃, activation time of 1.5 h.The results showed that adsorption capacity of acid scarlet G on activated carbon prepared under the optimum conditions increased with temperature, and the maximum adsorption amounts of acid red G were 153.6 mg/g, 165.6 mg/g, 180.4 mg/g, respectively, at 15, 25 and 35℃.Adsorption isotherms of acid scarlet G on the adsorbent can be described by Langmuir equation and the adsorption kinetics followed pseudo-second order kinetics model.Adsorption amount of acid scarlet G on the adsorbent decreased with the increasing solution pH;and the optimum adsorbent dose was 0.26 g/L.Acid scarlet G saturated adsorbent can be desorbed by alkaline solution and thermal treatment, and the regenerated adsorbents still possessed the high adsorption capacity for acid scarlet G.
