  • 摘要: 以城市污水厂的剩余污泥为原料,采用不同活化方法制备活性炭吸附剂,并对影响活化产物吸附性能的因素进行了研究.结果表明,化学活化法制备的活性炭污泥吸附剂性能较好,其最佳制备条件为:活化剂ZnCl2与H2SO4的浓度均为5mol·1-1(ZnCl2与H2SO4的复配比例为2:1),活化温度550℃,固液比1:2.5,活化时间2h.活性炭污泥吸附剂的碘吸附值为488.02mg·g-1,收率为86.6%,与商品颗粒活性炭对比,活性炭污泥吸附剂的比表面积为144.47m2·g-1,孔径分布比较宽,以过渡孔结构为主,电镜分析结果与之吻合,金属元素含量较高.
    Abstract: Taking surplus sludge as raw material and using different activations to prepare activated carbon adsorbents , and studying the affected factors on the adsorbent ability of the activated product have been conducted. The results showed that the activated carbon adsorbent made by chemical activation was better, and the optimum activator was complex of ZnCl2 and H2SO4, and the optimum preparation conditions were concention of two activators 5mol·1-1 (the ratio of ZnCl2 and H2SO4 was 2:1) , activation temperature 550℃, the ratio of solid to liquid 1:2.5 , time of activation 2 hours. The capacity of iodine adsorption was 488.02mg·g-1, the rate of achievement was 86.6%, contrasting commodity of pellet carbon, the abilities of activated carbon adsorbent were studied, the surface area, pore volume, micropore volume and average pore size were 144.47m2·g-1,0.05ml·g-1, 0.02ml·g-1and 38.51nm respectly. The pore structure was characterized by scanning electron microscope (SEM) , the content of metal elements was higher.
