去除效果.结果说明,鸢尾和香蒲在3种浓度的富养分化水体中均能生长,菖蒲在高浓

度水体中生长受到影响,这3种植物对不同浓度的富养分化水体中的氮、磷的去除率不同,鸢尾对3种不同富养分化程度水体的总氮的去除率分别为69％、88.8％、69.9％,菖蒲为66.5％、82.2％、54.2％,香蒲为64.1％、77％、74.3％；对水体总磷的去除率鸢尾为70％、87.7％、77.5％,菖蒲为54％、80％、55.8％,香蒲为44％、60.5％、61.6％.试验说明,3种植物均能显著改善富养分化水体的水质.各项指标综合分析可见,3种植物中鸢尾对富养分化水体的净化效果最好,香蒲对水体的净化效果最差,尤其是对水体中磷的去除.
