| Περίληψη | An integrated system was tested at pilot-scale for treating polluted water from the Marriot Lake in Egypt, comprising a settling technique followed by three parallel horizontal subsurface flow constructed wetland (HFCWs) units operating under a continuous flow mode; one HFCW unit was planted with Typha angustifolia and contained a perforated pipes network for enhanced passive aeration (CWA), one unit was planted without the perforated pipe network (CWR) and one served as a Control unit (unplanted and without perforated pipes). Changes in physicochemical parameters, BOD5, nutrients (nitrogen, phosphorus), microbial community, and trace metals at different hydraulic retention times (HRT; 0.5–6 h) and hydraulic loading rates (HLR; 750, 1000, 1250, and 2000 L/m2/d) were monitored. The CWA unit had an overall better performance than the CWR unit, while both planted units outperformed the Control unit. CWA showed the highest performance at HLR of 1000 L/m2/d and 4-6 h-HRT with 95.3% removal for turbidity, 83% for BOD5, 99.3% for ammonia nitrogen (NH4–N), 70.8% for Total Nitrogen (TN), and 66.7% for Total Phosphorus (TP), while higher NO3–N and NO2–N effluent concentrations were observed. Trace metals levels were significantly reduced and accumulated in plant tissues. Microbial communities’ densities fluctuated in the CWA unit. The integrated system with the settling stage and the planted CWA unit was proved to achieve a high removal efficiency and reached the national discharge limits, thus representing a novel nature-based solution for the sustainable remediation of polluted lake water. | en |
