| 摘 要： | 基于人工模拟自然条件的方法,选取狐尾藻(Myriophyllum verticillatum L.)、水芹菜(Oenanthe javanica)及黑麦草(Lolium perenne)等3种水生植物,对滇池入湖河道污水进行净化试验研究.探讨了水生植物对富营养化水体中氮、磷在不同相中的富集与转移效果.结果表明,沉积物相中,3种植物对氮的富集率为狐尾藻(64.71%)水芹菜(19.12%)黑麦草(5.88%)空白(-7.84%),磷的富集率为水芹菜(187.2%)狐尾藻(144.6%)黑麦草(130.5%)空白(31.2%);生物相中,氮的富集率为狐尾藻(4.15%)水芹菜(0.5%)黑麦草(-14.6%),磷的富集率为狐尾藻(9.6%)水芹菜(3.8%)黑麦草(-6.5%);水相中氮的去除率为黑麦草(95.11%)水芹菜(83.08%)狐尾藻(71.42%)空白(58.10%),磷的去除率为黑麦草(88.17%)狐尾藻(79.58%)水芹菜(73.09%)空白(20.19%).

| Abstract: | By artificially imitatiing natual conditions,three aquatic macrophytes,namely Myriophyllum verticillatum L.,Oenanthe javanica and Lolium perenne,were used to investigate their ability to purify the inflow river of Dianchi Lake.The efficiency of the system of enrichment and removal of nutrients in eutrophic water by aquatic macrophytes were discussed from the variation of the content of N and P in a three-phase structure of water-biology-sediment.All the hydrophytes absorbed the nutrients effectively.Myrioph... |
