人工湿地技术在暴雨径流处理中的应用(英文)

针对人工湿地对氮磷和重金属的去除现状,讨论了影响人工湿地处理效果的因素,如填料、植物、前处理等,提出需要从设计方法、水文资料统计、人工湿地组成部分及人工湿地的管理等方面入手改进人工湿地的处理效果.采用以径流污染控制和削减为目的的设计方法、以多年水文资料为根本的设计思路,以新型填料研发、耐淹及经济植物选择为应用前提,强化暴雨湿地管理,建立暴雨湿地数据库,是改进暴雨湿地净化效果的有效途径.

Application of constructed wetlands treatment technique for stormwater runoff pollution control

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 etc.that 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 wetlands.The design methods aimed at controlling the stormwater runoff should be based on the hydrological data accumulated for years.The 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 built.The discussion above should be effective in improving the pollution control effect in stormwater runoff by applying constructed wetlands.
