  • 摘要: 以城市生活污水厂脱水污泥和木屑的混合物为原料，利用ZnCl2为活化剂制备污泥活性炭。研究了活化温度、活化时间、固液比和活化剂浓度对吸附性能的影响。在活化温度为650℃、活化时间30 min、固液比1：1.5、活化剂浓度为5 mol·L-1的最佳工艺条件下，制备得到的活性炭碘吸附值为584.85 mg·g-1，利用扫描电镜可以观察到其发达的孔隙结构。将制备的污泥活性炭应用于兰炭废水处理中，结果表明，污泥活性炭的投加量为180 g·L-1，pH为7，吸附时间60 min，挥发酚和氨氮的去除率分别为73.38%和48.27%，废水中污染物浓度明显降低。
    Abstract: Sawdust and dewatered sludge from a municipal wastewater treatment plant were used as raw materials to prepare sludge-activated carbon; the activation agent was ZnCl2. The results showed optimal preparation conditions of:650℃ activation temperature, 30 min duration, solid-liquid ratio of 1:1.5, and activator concentration of 5 mol·L-1. The iodine adsorption value of the carbon was 584.85 mg·g-1 under the optimized conditions. The developed pore structure was observed by scanning electron microscopy. The sludge-activated carbon was used to treat semi-coking wastewater. The results showed considerably lower pollutant concentrations in wastewater:volatile phenol and ammonium removal rates were 73.38% and 48.27%, respectively, at a dosage of 180 g·L-1, pH 7, and adsorption time of 60 min.
