四种冬季水生植物组合对富营养化水体的净化效果
Purification efficiency of four combinations of aquatic macrophytes on eutrophic water body in winter
摘要
Abstract
Ten species of low temperature-tolerant aquatic macrophytes were chosen to construct four combinations of aquatic macrophytes to study their purification efficiency on eutrophic water body in winter. In non-macrophyte treatment (CK) , the removal efficiency of water total nitrogen (TN) , nitrite nitrogen (NOX-N), ammonium nitrogen (NH4-N) , and total phosphorus (TP) was 40.0% , 25.9% , 27. 3% , and 64. 5% , respectively. Combination 1 (Iris hexagonus Hy-brid + Rumex japonicas + Acorus gramineus "Ogan" + Juncus inflexus "Blue Arrows" ) grew lux-uriantly in the test eutrophic water body, and performed best in decreasing water TN, NOX-N, NH4-N, and TP, with the removal efficiency being 47. 8% , 52. 2% , 32.4% , and 70. 1% , re-spectively. Combination 2(7. hexagonus Hybrid + R. japonicas + A. gramineus "Ogan" + Hemerocallis middendorfii) could survive and had definite growth amount in the test eutrophic wa-ter, and the removal efficiency of water TN, NOX-N, NH4-N, and TP was 44. 2% , 58. 5% , 34. 6% and 67.8% , respectively. In contrast, both the combination 3 (R. japonicas + Lolium perenne + Chlorophytum comosum + Juncus pallidus R. Br. "Javelin" ) and the combination 4 (R. japonicas + L. perenne + C. comosum + Carex tristachya) only had an obvious efficiency in removing NOX-N but less efficiency in removing TN, NH4-N, and TP, due to the poor growth of C. comosum and C. tristachya. It was suggested that combinations 1 and 2 had better purification efficiency on eutrophic water body, being the suitable combination forms of aquatic macrophytes floating-bed under low temperature in winter.关键词
