【摘要】 采用泡沫塑料作为浮岛载体,进行7种蔬菜、6种花卉的单物种单池室内试验,通过跟踪水体TN、TP、COD、BOD5,研究不同蔬菜和花卉对栽培污水水体的净化作用.结果显示,13种植物对TN、TP、COD、BOD5的平均去除率分别为:82.31%(60 d生长期)、69.30%(60 d生长期)、73.23%(45 d生长期)8、5.94%(45 d生长期);单位生长量的去磷效果最好的是茄子,其次依次为:吊兰、叶用莴苣、石竹、辣椒、苋菜、空心菜、一串红、番茄、芹菜、万寿菊、矮牵牛、美人蕉.综合各因素,认为美人蕉和苋菜作为浮岛花卉和蔬菜类植物较为适合.更多还原

【Abstract】 The purification of water by cultivating vegetables and flowers on artificial floating island,which was set up using foams was investigated by monitoring TN,TP,COD and BOD5 of the water in the single species experiment in single water tank indoor of 7 kinds of vegetables and 6 kinds of flowers.Results indicate that: 82.31% of TN,69.30% of TP could be removed by 13 kinds of plants in 60 days averagely;73.23% of COD,85.94% of BOD5 could be removed by 13 kinds of plants in 45 days averagely;the best effectiveness of TP subtractive per unit growth was displayed by eggplant,while bracket-plant,butter head lettuce,chinese pink,pepper,amaranth,swamp cabbage,scarlet sage,tomato,celery,tagetes erecta,petunia hybrida,canna followed.But canna and amaranth are more adapted to plant on the artificial floating island upon comprehensive consideration.更多还原
