摘要：In order to improve the pollution control effect of nitrogen phosphorus and heavy metals in stormwater runoff by using the constructed wetlands factors such as medium plants pretreatments *** may influence the removal efficiency are discussed based on the current studies. The pollution control effect can be enhanced by the improvement of the design methods the components and management of constructed *** design methods aimed at controlling the stormwater runoff should be based on the hydrological data accumulated for *** development of novel medium and the selection of plants i.e. flood-tolerant and economical should be considered in advance. The management of constructed wetlands should be enhanced and the database of the stormwater in wetlands should be *** discussion above should be effective in improving the pollution control effect in stormwater runoff by applying constructed wetlands.
