摘    要:构建新型浮动绿岛,选用花叶芦竹(Arundo donaxvar versicolor)对上海市白莲泾河流进行治理试验。试验表明,人工浮岛在曝晒或暴雨、河道闸门开闭产生水位变化和水流急变的环境条件下,都能正常浮动稳定于水体中发挥浮岛功能,并可向浮岛内加水调节吃水深度。浮体浮力大于800 N,浮体间可连接与组合,安全性强。花叶芦竹浮岛系统能有效降低水体中氮、磷的含量。栽种密度为30株/m2时,对白莲泾水质总氮平均去除率为81.79%,对总磷平均去除率为55.88%,具有明显改善水质和美化环境的功能。

关 键 词:浮动绿岛  花叶芦竹      去除率  水景  白莲泾

Abstract:A new type artificial floating-island raft was designed for a trial bioremediation at Bai Lian Jing River in Shanghai.An aquatic plant,Arundo donax var versicolor,was used to absorb nitrogen and phosphorus nutrients in the floating-island raft.It was showed that the floating-island raft could stably floated in the water of Bai Lian Jing River when river strobes sharp opened or closed and the water depth changed largely.It also had the functions against insolation and rainstorm.The floating-island raft could be regulated in different water depth by pumping water in or out.The maximum raft flotage was 800 N.And the raft security could be increased for several rafts connected one by one.Arundo donax var versicolor planted at basketries with different density below water surface in the floating-island rafts,and could reduce N and P concentrations efficiently.When the planting density was 30/m2,the removal rate of total N and P in Bai Lian Jing River water were as high as 81.79% and 55.88%,respectively.It indicated that the floating island system with Arundo donax var versicolor was characterized of improving water quality and water environment efficiently.
Keywords:floating-island raft  Arundo donax var versicolor  nitrogen  phosphorus  removal rates  Bai lian jing River
