Abstract: Activated carbon was prepared from pyrolusite-added sewage sludge by ZnCl2 activation method. Its structure and performance were characterized by BET, SEM, FT-IR, XRD, O2-TPO and TGA, and the impact of pyrolusite to preparing process of activated carbon was analyzed. The result showed that the specific surface area, total pore volume, micro-pore volume, average pore radius and iodine adsorption of activated carbon from pyrolusite-added sewage sludge can reach 354.198m2/g, 0.8096cm3/g, 0.159cm3/g, 4.6nm and 558.05mg/g respectively under the experiment condition, and the above performance parameters were increased in a great extent compared with activated carbon from sewage sludge. Pyrolusite catalyzed the decomposition of organics in the sewage sludge, supply the new generated carbon more framework, facilitated the carbon deposit and contributed to the formation of microcrystalline structure simultaneously in the preparing process of activated carbon from pyrolusite-added sewage sludge.
