摘　　要：采用浮岛无土栽培的方法,以人工水桶为模拟场所,通过在桶内的生活污水水体表面混合种植各种植物,研究植物的吸收和吸附作用、微生物的协同作用以及水体中TN、TP、COD的降解等,结果表明混合型植物人工浮岛对TN、TP的去除效果比单一植物要好,COD的去除率也达到80%,对于生活污水的处理具有广阔的应用前景。Several kinds of plant were planted in the sewage water with the technology of soilless culture in a barrel, and TN, TP and COD were removed by the absorbing and sorption of plants, cooperated with bacteria. The experimental results show that more TP and TN can be removed by the hybrid-plant artificial floating island than by a single plant, and the removal ratio of COD reached 80 %. It is proved that the sewage treatment by the hybrid-plant artificial floating island has broad application prospects.
