Abstract：
Industrial effluents pose a serious environmental problem, because they contain toxic contaminants mainly heavy metals that are the most dangerous to humans, animals, plants, and the environment in general. Phytoremediation using macrophytes is an adopted technique for the environment decontamination due to its efficiency and cost-effectiveness. The present study aims to highlight the capabilities of macrophytes to remove heavy metals from wastewater of Biskra region (Algeria). The methodology consists of filling out the filters planted with Arundo donax and Phragmites australis with raw industrial wastewater, then recovering decontaminated water after 15 days to assess removal of lead, copper, zinc, and iron. Both plants had shown a good efficiency for the removal of metals loaded in wastewater eliminating about 94 to 98% of initial concentration. In addition, calculated bioaccumulation factor (BAF) had confirmed the accumulation of heavy metals in different parts of experimental plants; recorded values of BAF > 1 allowed the consideration of Arundo donax and Phragmites australis as good hyper-accumulator plants. Obtained results confirm the efficiency of phytoremediation technology using macrophytes for the wastewater treatment in particular and the environment decontamination in general.
摘要：
工业废水造成严重的环境问题，因为它们含有有毒污染物，主要是对人类最危险的重金属，动物,植物,和一般的环境。由于其效率和成本效益，使用大型植物的植物修复是用于环境净化的一种采用的技术。本研究旨在强调大型植物从比斯克拉地区（阿尔及利亚）的废水中去除重金属的能力。该方法包括用原工业废水填充种植有Arundodonax和芦苇的过滤器，然后在15天后回收去污染的水，以评估铅的去除，铜，锌，和铁。两家工厂均显示出去除废水中负载的金属的良好效率，从而消除了约94％至98％的初始浓度。此外,计算的生物积累因子（BAF）证实了重金属在实验植物不同部位的积累；记录的BAF值>1允许将Arundodonax和芦苇视为良好的超积累植物。获得的结果证实了使用大型植物进行废水处理和一般环境净化的植物修复技术的效率。
