【摘要】 污水污泥制备的多孔材料,是污泥处置的有效途径和去除有害污染物的有效吸附剂。本研究的目的是从污水污泥中制备污泥衍生材料的物理和化学性质的着手,了解其结构特点。在550℃下,3mol/L氯化锌活化脱水污泥,用氮气作保护气体热解1h,制备的含污泥含碳材料。对其表面积和孔大小分布情况,表面化学结构和物理形貌进行研究,并检测溶液中碘值和Cu²⁺的吸附容量。结果表明污水污泥制备的吸附剂具有显著的微孔和中孔结构,对碘和Cu²⁺有独特的吸附容量。与商用活性炭相比,具有不同的物理和化学性质。更多还原

【Abstract】 Preparation of porous material from sludge sewage,is an effective adsorbent of the elimination of harmful pollutant and is a best way of the disposal of sludge sewage.It is based on physics and chemical property of actived carbon,realised its unique characteristic.Under the condition of the concentration of ZnCl₂ 3M,activation temperature of 550℃,activating time 1h,the protection of N₂,prepares the carbonaceous adsorbents.It studies the surface area and distribution of the pores,considering the surface chemistry and physical characteristic,examining the iodine value and the adsorpted capacity of Cu²⁺.The result is that carbonaceous adsorbent has remarkble pore and hole structure.The effect of adsorption was better than power actived carbon。更多还原
