摘要
采用生态浮床的形式,将黄菖蒲、美人蕉生态栽培植物单作、混作,根据植物的生长状况和植物对水体中氮磷等污染有机物的去除特征、去除率探明黄菖蒲、美人蕉处理城市景观水体的净化效果。经过60d的试验研究发现,植物生长良好,氮磷及有机污染物质得到有效去除。结果表明,单作黄菖蒲比单作美人蕉更能有效去除氮营养元素,对TN的去除率可达69.4%;单作美人蕉比单作黄菖蒲更能有效去除磷营养元素,对TP的去除率可达70.5%;混作TN、TP的去除率分别为47.8%、56.8%,去除氨氮、高锰酸盐效果比单作更明显。
Canna generalis and iris pseudacorus are sole and mixed cropped in the ecological floating beds as the tested plants. According to growth status and the removing of nitrogen and phosphorus pollution in urban landscape water,the purifying effects of these plants are proved up. After 60 days of experimental study,plants grow well and the removal rates of nitrogen,phosphorus and organic pollutants are effective. Canna generalis monoculture is better than iris pseudacorus in removing nitrogen nutrient elements,and the removal rate of TN can reach 69. 4%; iris pseudacorus monoculture is better than canna generalis in removing phosphorus nutrient elements and the removal rate can reach 70. 5%; the removal rate of mixed approximation TN and TP is 47. 8% and 56. 8% respectively and the effect of removing ammonia nitrogen and CODMnis more obvious than monoculture.
