中文摘要: 纳米级重金属颗粒物不仅具有纳米颗粒物特殊的生物毒性,而且在水体中能逸出重金属离子。因此,水体中存在的纳米级重金属颗粒物将严重危害人体健康和生态环境。本课题利用浒苔-铝盐复配体系可形成大且密实的絮体且同时能吸附重金属离子的特性,用于混凝去除水体中的纳米级重金属颗粒物,实现同步去除纳米颗粒物及其逸出的重金属离子,从而有效控制纳米级重金属颗粒物污染。同时,通过对纳米颗粒物聚集动力学、混凝过程及絮体性质的研究,阐明浒苔-铝盐复配混凝同步去除纳米级重金属颗粒物及重金属离子的行为和作用机制。该研究对于保护我国水环境具有十分重要的理论意义和实用价值。

英文摘要: Nano-sized heavy metal particles not only have special biological toxicity, but also can release heavy metal ions in water. Therefore, nano heavy metal particles existing in the water will cause serious damage to human health and ecological environment.In this project, a compound system based on enteromorpha - aluminum salt would be used to treat nano heavy metal particles. Both nano particles and heavy metal ions would be synchronously removed because the compound system based on enteromorpha - aluminum salt would form large, strength flocs and adsorb heavy metal ions. This would effectively control pollution of nano heavy metal particle. Meanwhile, the removal process and mechanism of Nano heavy metal particles would be illuminated by the aggregation dynamics, coagulation process and the flocs properties. This study is important for protecting water environment.
