摘　　要：研究一种新型的浮岛结构(复合生态浮岛),采用陶粒和亲水性矿物纤维作为载体,高羊茅作为浮岛植物,对重度富营养化水进行处理.初步的研究结果表明:高羊茅适宜作为浮岛植物,曝气条件对高羊茅出苗状况影响较大.经过34 d的试验,未曝气复合生态浮岛CODMn去除率可达到65.7%,曝气条件下达到70.0%;对于TP的去除,未曝气复合生态浮岛和曝气复合生态浮岛两者达到的去除率分别为85.5%、89.1%;NO3--N和ORP、pH的变化曲线表明,水样中存在较强烈的硝化与反硝化作用.A novel floating island construction （complex ecological floating island） was put forward in this paper. Ceramisites and hydfophilic miner fiber were selected as support materials, Festuca arundinacea Schcreb was selected as plant. Static experiments on purification of severe eutrophicated water body by the floation island were carried out. Primary results indicated that Festuca arundinacea Schreb was a suitable plant for the floating island. Aeration is an important factor influencing the burgeon of plant. In the 34 d experiment, the removal efficiency of CODMn of non-aerated island was 65.7%,while the removal efficiency of aerated island was 70. 0%. The removal efficiencies of TP of non-aerated and aerated island were 85.5% ,89. 1%, respectively. The varieties of NO3^--N and ORP, pH indicated that there was strong nitrification-denitrification in the system.
