| 摘 要： | 以污水处理厂剩余污泥为原料,添加适量天然软锰矿,采用氯化锌化学活化法制备活性炭,用于吸附活性艳红X-3B染料.结果表明,软锰矿的添加可以改善污泥活性炭的吸附性能,使其对染料的饱和吸附容量(Qm)较未投加软锰矿的污泥活性炭增加50mg/g以上,最大可提高56.5%;软锰矿的投加量因污泥种类而异,控制在0.2%～2%范围内;活性炭的最适宜投加量为4g/L,吸附时间90min,pH值对吸附的影响不大;吸附热力学Langmuir模型比Freundlich模型更适合描述本研究中的等温吸附系统.

| Abstract: | Activated carbons were prepared from pyrolusite-added sewage sludge by ZnCl2 activation method.Batch adsorption experiments were performed by applying the activated carbons into wastewater of synthetic reactive brilliant red X-3B.The results indicated that the addition of pyrolusite could improve the adsorptive proprties of the activated carbon.The adsorbent concentration and adsorption contact time for the optimum dye-removal were 4g/L and 90min,respectively,while the influence of solution pH value seemed ... |
