Abstract

Abstract

Urban stormwater runoff has emerged as a critical environmental challenge， significantly impacting aquatic ecosystems by transporting pollutants such as nitrogen， phosphorus， and organic matter into the receiving water bodies. These contaminants contribute to water quality degradation and disrupt ecological balance， necessitating effective and sustainable mitigation strategies. Aquatic plants have shown considerable promise in addressing this issue due to their natural pollutant removal capabilities. This study investigated the purification efficiencies of four aquatic plant species， Acorus calamus， Lythrum salicaria， Thalia dealbata， and Iristectorum， and evaluated their treatment efficiencies on TP， TN and COD in rainwater by simulating urban rainwater runoff hydroponic experiments. It was found that the combinations of Iris tectorum and Thalia dealbata （IT）， Iris tectorum and Acorus calamus （IA）， Thalia dealbata and Lythrum salicaria （TL）， and Lythrum salicaria and Acorus calamus （LA） showed different effects on the removal of pollutants from rainwater runoff. The results showed that the TN removal rate of each plant combination ranged from 90% to 97%， 87% to 93%， 90% to 93% and 93% to 97%， respectively. The co-cultured Thalia dealbata and Lythrum salicaria groupshowed the best TN removal effect. The TP removal rate of the four plant combinations varied in the range of 83%~91%， 78%~85%， 75%~86% and 83%~86%， respectively. The co-cultured Thalia dealbata and Lythrum salicaria group showed the best performance in growth and nitrogen and phosphorus removal， and were preferentially selected as purification plants for the removal of TN and TP. The COD removal rate of the four plant combinations varied in the range of 28%~94%， 35%~95%， 65%~97% and 15%~87%， respectively. Among them， the co-cultured Iristectorum and Acorus calamus group performed well in COD treatment of urban rainwater runoff， while the co-cultured Lythrum salicaria and Acorus calamus group had the weakest purification ability. Additionally， the study underscored the critical role of plant morphological traits， such as root structure and growth dynamics， in pollutant removal. Plants combinations featuring fast-growing species with extensive root systems were generally more effective in nutrient and organic pollutant uptake. These findings validate the potential of aquatic plants as eco-friendly， nature-based solutions for urban stormwater management.
