TL;DR: In this article, the authors investigated the effects of vegetation, hydraulic retention time (HRT), and water temperature on P removal from polluted river water and quantified the contributions of different P removal pathways in surface wetlands.
Abstract: A number of studies have showed that the mass removal rates of phosphorus (P) in different constructed wetlands (CWs) varied significantly, and it is essential to quantify the contributions of major P removal processes in order to improve system design. The objective of this study was to investigate the effects of vegetation, hydraulic retention time (HRT), and water temperature on P removal from polluted river water and to quantify the contributions of different P removal pathways in surface CWs. Results showed that the average total P removal rates ranged between 2.69 and 20.84mg/ (m 2 day) in different seasons and were influenced significantly by vegetation, HRT, and water temperature. According to the mass balance approach, plant uptake removed 4.81‐22.33% of P input, while media storage contributed 36.16‐49.66%. Other P removal processes such as microbiota uptake removed around 0.26‐4.13%. Media storage and plant uptake were identified as the main P removal processes in surface CWs treating polluted river water. This illustrated the importance of selecting media and plants in CWs for future practical application.
