| 英文摘要 | The performance of constructed wetlands (CWs), the mainstream technology for tertiary effluent treatment, is influenced by various environmental factors, including fluctuations in water quality and quantity. Increasingly stringent effluent standards in wastewater treatment, owing to increasing awareness regarding ecological safety, require high-performing CWs that show adaptability to these changes in environmental factors. In this study, we systematically investigated the optimization of the hydraulic performance of a novel permeable modular constructed wetland (PMCW) by varying the configuration of slotted baffles. The results obtained showed that slot density exerts a significantly stronger effect on wetland hydraulic performance than slot direction, and compared with high-density slotted baffles, low-density slotted baffles appropriately extended the hydraulic retention time of water within the CW and improved flow velocity distribution, thus was more beneficial for improving hydraulic performance. Additionally, relative to vertically slotted baffles, horizontally slotted baffles were more beneficial for improving hydraulic performance as this baffle configuration ensured uniform water distribution and reduced the occurrence of low-flow velocity zones. Combinations of unlike baffle types resulted in more complex flow paths within the CW, limiting hydraulic performance. However, combinations of identical baffle types improved hydraulic performance, with the combination of low-density horizontal slotted baffles showing the best hydraulic performance. The optimal baffle combination and modular plant growth within biological units further improved both hydraulic performance as well as pollutant removal capacity in the PMCW. Taken together, these findings indicated that PMCWs have great potential for improving hydraulic performance and enhancing pollutant removal. |
