Effects of different macrophytes in constructed wetlands on treating polluted rivers in China
River pollution has received more and more attentions in recent years. Besides controlling point and non-point pollution emissions, an economical and environment friendly system of treating polluted rivers is needed urgently in the whole world. The constructed wetlands (CWs) system is a significant option for treating polluted rivers by simulating natural wetlands. Macrophyte removal of nutrients is the most important way for wetland pollution treatment while macrophyte community can also lead to high evapotranspiration which will results in huge loss of water in CWs. Some literatures about comparison of different macrophytes to remove nutrients have been carried out in these years. However, few researches considered plant uptake and evapotranspiration simultaneously during the comparison of different macrophytes to treat pollution. In the study, we will compare the effects of different macrophytes in CWs on treating polluted rivers under considering both nutrients removal and evapotranspiration. The results show that the choice of macrophytes is significant for pollution treatment. When we analysis the water purification effect of macrophytes, both nutrients removal and evapotranspiration should be considered in the future.
