摘要
磷是湖泊富营养化的主要诱导因素之一,如何有效控制湖泊的磷负荷显得至关重要。文章总结了人工湿地基质除磷的相关机理,包括化学作用,微生物作用和物理作用。通常情况下,认为化学作用是湿地基质最主要的磷去除途径。另外,文章也分析了人工湿地基质除磷的主要影响因素,并对基质除磷的研究前景进行了展望。
Phosphorus is one of the main limited factors to lake eutrophication. How to effectively control the phosphorus load of the lakes is very important. This paper summarized the related mechanisms of CWs controlling phosphorus which included chemical action,microbiology action and physical action. Generally speaking,chemical action is the main approach to remove phosphorus by substrate in CWs. In addition,this paper also analyzed the main influencing factors to substrates in CWs removing phosphorus,and gave some opinions about its prospects.
