摘要

本研究调查了利用种植有单一栽培物种的生物膜湿地(BW)处理哈塔尔工业区综合废水的情况:Eichhornia crassipes (EAC)、Pistia stratiotes (WL) 和 Arundo donax (GR)。每个物种在有机物降解、金属吸收和 pH 值稳定方面都表现出不同的能力。种植了 EAC 的 BW2 对总固体(TS)和总悬浮固体(TSS)的去除率最高,分别达到 66% 和 65%。GR 有效地将初始 COD 浓度从 232 mg/L 降至 58.67 mg/L,而 EAC 和 WL 则分别降至 72.78 mg/L 和 70.67 mg/L。总体而言,工厂效率排序为 EAC > GR > WL。这些发现凸显了这些植物物种在协同生物降解系统中的潜力,突出了它们作为复杂工业废水治理天然解决方案的作用。这项研究有助于推动生态友好型废水处理方法的发展,并为工业环境中的可持续实践提供了应用前景。研究结果有助于了解复杂工业废水的自然解决方案。

Sustainable treatment of combined industrial wastewater: synergistic phytoremediation with Eichhornia crassipes, Pistia stratiotes, and Arundo donax in biofilm wetlands.

This study investigates the treatment of combined wastewater from Hattar Industrial Estate using Biofilm Wetlands (BW) planted with monoculture species: Eichhornia crassipes (EAC), Pistia stratiotes (WL), and Arundo donax (GR). Each species showed distinct capabilities in organic degradation, metal uptake, and pH stabilization. BW2, planted with EAC, achieved the highest total solids (TS) and total suspended solids (TSS) removal efficiencies of 66% and 65%, respectively. GR effectively reduced initial COD concentrations from 232 mg/L to 58.67 mg/L, while EAC and WL reached reductions to 72.78 mg/L and 70.67 mg/L, respectively. Overall, the plant efficiency ranking was EAC > GR > WL. These findings underscore the potential of these plant species in synergistic BW systems, highlighting their role as natural solutions for remediating complex industrial effluents. This research contributes to advancing eco-friendly wastewater treatment approaches, suggesting promising applications for sustainable practices in industrial contexts.RESEARCH HIGHLIGHTSThis research assessed the effectiveness of phytoremediation using Eichhornia crassipes, Pistia stratiotes, and Arundo donax for removing pollutants i.e. heavy metals (Cd, Pb, Ni, K, Ca, Mg, Na, Fe, Hg) nitrates, phosphates and sulfates from combined industrial wastewater of Hattar Industrial Estate Pakistan.It highlighted the potential of selected plant species' as natural treatment systems, providing crucial insights into their efficiency.Findings contribute to understanding nature-based solutions for complex industrial effluents.

期刊介绍: The International Journal of Phytoremediation (IJP) is the first journal devoted to the publication of laboratory and field research describing the use of plant systems to solve environmental problems by enabling the remediation of soil, water, and air quality and by restoring ecosystem services in managed landscapes. Traditional phytoremediation has largely focused on soil and groundwater clean-up of hazardous contaminants. Phytotechnology expands this umbrella to include many of the natural resource management challenges we face in cities, on farms, and other landscapes more integrated with daily public activities. Wetlands that treat wastewater, rain gardens that treat stormwater, poplar tree plantings that contain pollutants, urban tree canopies that treat air pollution, and specialized plants that treat decommissioned mine sites are just a few examples of phytotechnologies.
