The use of fast-growing tree species, such as Casuarina glauca for wastewater treatment could improve the quality of wastewater and offer an ecological and sustainable system. A hydroponically experiment was conducted to evaluate C. glauca ability to remove heavy metals from secondary treated urban wastewater (SWW). The effect of the SWW on plant biomass, some physiological parameters, heavy metals (Cd, Pb, Ni and Zn) bioaccumulation and removal from wastewater was evaluated. After 28 days, wastewater treatment C. glauca showed high efficiency for the removal of pathogenic bacteria such as faecal coliforms and faecal streptococci from SWW. A significant reduction was found for electrical conductivity, biochemical oxygen demand, chemical oxygen demand and suspended solids with 31%, 92%, 83% and 31% respectively. Casuarina glauca plants were able to remove heavy metal ions Cd, Pb, Ni and Zn from SWW and the removal efficiency was 92%, 77%, 83% and 73%, respectively. Casuarina glauca plants accumulated concentrations of heavy metals (Cd, Pb, Ni and Zn) in their roots higher than the shoots. SWW had a remarkable effect on plant growth and photosynthetic capacity in C. glauca compared with plants grown in tap water (control). The results indicated that C. glauca can act as scavengers of heavy metal ions from polluted water and confirms their ability for wastewater treatment.

使用快速生长的树种，例如用于废水处理的木麻黄可以改善废水质量并提供一个生态和可持续的系统。进行了水培实验以评估C. glauca从二级处理的城市废水 (SWW) 中去除重金属的能力。评估了 SWW 对植物生物量、一些生理参数、重金属（Cd、Pb、Ni 和 Zn）生物积累和从废水中去除的影响。28 天后，废水处理C. glauca显示了从 SWW 中去除致病菌（如粪便大肠菌群和粪便链球菌）的高效性。发现电导率、生化需氧量、化学需氧量和悬浮固体显着降低，分别为 31%、92%、83% 和 31%。木麻黄植物能够去除SWW中的重金属离子Cd、Pb、Ni和Zn，去除效率分别为92%、77%、83%和73%。木麻黄植物在其根部积累的重金属（Cd、Pb、Ni 和 Zn）浓度高于枝条。与在自来水中生长的植物（对照）相比，SWW 对C. glauca 中的植物生长和光合能力具有显着影响。结果表明，C. glauca 可以作为污水中重金属离子的清除剂，并证实了它们处理废水的能力。
