摘　　要：通过在同等条件下的室内静态模拟试验，选取灯心草、水葱和梭鱼草及其混合型植物人工浮岛为研究对象，分析比较了它们对富营养化水体水质净化效果。研究表明：在静态条件下，植物人工浮岛对总氮和总磷的去除率分别为38.9%-60.3%、21.4%-44.1%；混合型植物人工浮岛比单一型植物人工浮岛去除总氮、总磷的效果都要好，其中，尤以梭鱼草、水葱、灯心草3种植物组成的人工浮岛去除总氮、总磷的效果最好，分别为60.3%、44.1%。Through indoor static simulation test with the same conditions, the artificial floating islands with Juncus effusus, Scirpus tabernaemontani, Pontederia cordata or the three plants mixed were chosen as the research objects to analyze and compare the removal effect of them to the eutrophic water. The results showed that in the static condition, the total removal rate of artificial floating island with plant to total nitrogen and total phosphorus was 38.9%-60.3% and 21.4%-44.1%, respectively. The artificial floating island with the three plants mixed had better removal effect to total nitrogen and total phosphorus than artificial floating island with single plant, and the artificial floating island with Pontederia cordata, Scirpus tabernaemontani and Juncus effusus had the best removal effect to total nitrogen and total phosphorus by 60.3% and 44.1%, respectively.
