以废弃芦苇为原料、硫化钠(Na_(2)S)为改性剂,制备了对Pb^(2+)、Cd^(2+)、Zn^(2+)具有高效吸附性能的Na_(2)S改性生物炭(BCS)。通过扫描电镜-能谱(SEM-EDS)、红外光谱(FTIR)、元素分析等手段对改性前后的生物炭进行了表征。结果显示,Na_(2)S改性能够为生物炭引入多种含硫官能团,提升孔体积并增加比表面积。Langmuir模型拟合结果表明,随着改性剂Na_(2)S溶液浓度的增加,BCS对重金属离子的吸附能力得到提升。在pH为2.0~6.0的范围内,BCS对重金属离子的吸附能力随pH增加逐步增强。在pH=6.0时,BCS对Pb^(2+)、Cd^(2+)、Zn^(2+)的最大吸附量分别为494.99、131.14、94.89 mg/g。根据动力学实验结果可知,BCS对重金属离子的吸附行为符合伪二级动力学模型。吸附机理主要包括表面官能团的络合、离子交换和静电吸附。本研究可为废弃物的再利用以及废水中的重金属的高效去除提供一种环境友好且可行的解决方案。

随着人口数量增长与城市工业化进程的不断加快,对水资源的需求日益剧增。为了缓解水资源压力同时减轻城市排水系统的负担,开展了超滤-纳滤双膜工艺深度净化天然雨水的试验,探究了双膜工艺对天然雨水的水质净化效果。结果表明,超滤-纳滤双膜工艺可以有效降低雨水中污染物含量,对UV_(254)、总溶解性固体、总有机碳和电导率的平均去除率分别为87.5%、66.7%、32.0%和61.4%。双膜技术实现了对雨水中固体颗粒和溶解性有机物的高效去除,同时对荧光类有机物也显示出优异的截留效果。相比于常规的水处理工艺(混凝-沉淀-过滤工艺),双膜技术因具有出水水质优异、无二次污染、处理效率高等优势,在雨水的高效分离和资源化利用领域展现出较大的应用潜力。
