摘要
针对辽河流域特定的气候条件并结合自身研究成果,从人工湿地类型的选择、湿地植物在去除氮磷中的作用、人工湿地对废水水质和水量的要求等方面对人工湿地进行了综述。通过对国外人工湿地治理面源污染的实际工程以及辽河流域已经开展的人工湿地治理工程的分析,说明人工湿地是一种有效缓解辽河流域面源污染的技术手段。
Considering the particular climatic condition in Liaohe river basin and combining our research findings,the paper overviewed the constructed wetlands from aspects of the type selection of constructed wetlands,elimination capacity of nitrogen and phosphorus of wetland plants and demand of water quality and volume.Through the introduction of actual engineering from abroad and constructed wetlands management engineering in Liaohe river basin,constructed wetland is consider as a type of effective technology in alleviating non-point source pollution of Liaohe river basin.
